Healthcare staffing agencies are sitting on a gold mine they mostly ignore: nurses, allied health pros, and locum physicians who took one assignment and then went quiet. SIA estimates US healthcare staffing at roughly $38.7 billion in 2026, and per diem and travel segments are only now stabilizing after the post-pandemic correction. That means every dormant clinician in your database is worth real money, and reactivating one costs a fraction of sourcing a new candidate. Research on reactivation consistently shows phone calls outperform email by a wide margin, because a live conversation lets someone find out why the clinician went quiet and address it on the spot. The catch is practical. Your recruiters are working hot reqs, not dialing a list of 12-month dormants. This guide compares five options for running win-back and reactivation calls in 2026, from managed AI calling services to human-agent platforms and dialer software, so you can pick the one that fits your list, your budget, and your compliance posture.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. No per-seat charges, no platform bill, and the first campaign review is free.
My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. Owned and operated by AIQ Labs, based in Halifax, Nova Scotia with a US operating base in Austin, Texas, the promise is simple: run more useful calls without building a bigger call center. For a healthcare staffing agency, that means a Win-Back & Reactivation campaign against your dormant clinician database, typically 12 to 24 month dormants, without pulling a recruiter off active reqs. You buy campaigns that they run for you, each built around one clear goal and quoted in full before launch. What sets My AI Call Center apart is list discipline. Before any campaign launches, the team reviews your list source, consent records, and calling windows. Bought lists without clear permission records are flagged and, in most cases, declined. If your list won't support the campaign, they tell you plainly before you spend anything. That matters for staffing agencies holding years of candidate data of varying consent quality. Compliance is built in too: AI voices are treated as artificial voices under the TCPA with prior express consent required, state quiet hours are honored, AI disclosure happens on every call, and keyword opt-outs like STOP and REVOKE are logged and honored immediately. Hot leads transfer to your recruiting team live or land in your CRM, and every campaign ends with a named outcome report: disposition codes, per-call notes, routed follow-ups, and opt-out and DNC logs. They report what actually happened, with no invented numbers.
Pros
- Managed service: you buy campaigns, not software seats your team has to learn
- List and consent review happens before you spend a dollar, which reduces TCPA risk on old candidate databases
- Transparent pricing locked before launch, with no mid-campaign rate changes
- Every call produces a named outcome routed back to your recruiters, with no invented numbers
- Free first campaign review, so you know the full cost before approving anything
Cons
- Not a self-serve platform; you work with their team rather than running campaigns in-house
- Only works with approved, permissioned, or reviewed lists, so undocumented lists may be declined
- AI voices may not suit every brand's preference, though disclosure is provided on every call
Best for: Healthcare staffing agencies and multi-location recruiting firms that want a hands-off, compliance-first way to reactivate dormant clinicians without hiring callers or buying software.
#2 CallMyCustomers — Contact for pricing. A one-time setup fee based on list size is quoted at the free list review, plus outreach minutes at 9¢ to 21¢ per minute depending on volume, with texts and emails included.
CallMyCustomers is a done-for-you customer reactivation service built for US service businesses that depend on repeat revenue. According to its website, the service works from whatever list you already have, whether that's a CRM, a spreadsheet, or an export from your applicant tracking system, with no new software to buy or learn. For a healthcare staffing agency, that means you can hand over a list of lapsed travel nurses or per diem clinicians and have real people make the calls on your behalf. The core of the model is approval-first. The owner signs off on every script, offer, and message before any outreach begins, so the campaign reflects your voice. A free list review shows your revenue potential and exact cost before you commit. The company lists 16 specialized campaign types, including customer win-back, past-quote win-back, seasonal reminders, and renewal and membership retention. On the compliance side, CallMyCustomers states it works only from real customer lists, honors opt-outs immediately, follows TCPA and A2P 10DLC regulations, and operates under BAA/HIPAA where required. Campaigns typically run two to four weeks end to end, with replies routing directly into your booking or onboarding process.
Pros
- Free list review means zero financial commitment before you know what your list can produce
- No new software to learn and no internal staff time required
- You approve every script and offer before anything is sent
- Replies route directly into your existing booking flow
Cons
- Not a self-serve platform; businesses wanting a DIY tool should look elsewhere
- Setup fee is quoted rather than published, so budgeting requires the initial review call
- Currently serves US businesses only
Best for: Healthcare staffing agencies that want a fully managed reactivation service run by human callers, with full approval control over every message.
#3 Upcall — Contact for pricing. Upcall offers a free consultation to scope campaigns.
Upcall is a conversation-driven marketing and sales platform that specializes in win-back campaigns using real people on the phone. According to its website, the company has worked with more than 4,000 companies and positions itself as a leading outbound calling solution for reconnecting with past clients. The model is straightforward: you forward or upload your leads, their callers engage those contacts with proven scripts, and you receive results and insights through a real-time dashboard. For a healthcare staffing agency, the appeal is human judgment on every call. Upcall's callers work to understand why a nurse or allied health clinician went quiet, uncover new opportunities, and reintroduce your agency with current assignments and rates. The platform lists features including automated follow-up calls, real-time reporting, instant notification when a campaign goal is reached, appointment booking directly into your calendar, and a free script consultation to shape the outreach before it starts. The dashboard is a genuine strength: you can monitor key metrics as the campaign runs and adjust based on what the data shows rather than waiting for a post-campaign report. That visibility matters when you're testing a reactivation message against a long-dormant clinician list.
Pros
- Human judgment on every call, which helps uncover why a clinician went quiet
- Real-time reporting lets you adjust messaging mid-campaign
- Free script consultation shapes outreach before it starts
- Appointment booking flows directly into your calendar
Cons
- Pricing isn't published, so budgeting requires a consultation call
- Human caller costs generally run higher than automated alternatives on large lists
- Requires forwarding or uploading leads, so list prep falls on your team
Best for: Healthcare staffing agencies that want human callers on every reactivation call and real-time visibility into campaign performance.
#4 Retell AI — Contact for pricing.
Retell AI is a self-serve platform for building AI voice agents, and its documentation includes a detailed playbook for running lead reactivation campaigns with AI calls. For a healthcare staffing agency with technical resources, it offers a way to run reactivation calling in-house at scale. The approach Retell describes is structured: you build a list of opted-in leads who went dark, lost or stalled deals, and lapsed customers, then run batch calls with defined cadence and stop rules so nobody gets called too often. According to Retell's documentation, every connected call is transcribed and tagged with a reactivation outcome such as interested, not now, or do not call, so the list that goes back to your recruiters holds only people worth a conversation. The platform supports dynamic variables per contact, post-call SMS triggered by call results, warm transfers to reps, and CRM write-backs to HubSpot, Salesforce, Microsoft Dynamics 365, GoHighLevel, and Zoho. Retell is also direct about compliance: its guidance notes that the FCC treats AI-generated voices as artificial voices under the TCPA, generally requiring prior express consent, and recommends checking each list with your counsel. Note that Retell has no automatic redial, so your team plans and places each attempt, either through daily batch uploads or your own scheduler via API.
Pros
- Full control over list building, cadence, and stop rules
- Every connected call is transcribed and tagged, so reps only work viable contacts
- Broad CRM integrations for outcome write-backs
- Transparent compliance guidance on TCPA and AI voice rules
Cons
- Self-serve only: your team builds and operates everything, including redial planning since there's no automatic redial
- Requires engineering effort for scheduling, suppression checks, and SMS setup
- Compliance review of consent per list segment falls entirely on you
Best for: Healthcare staffing agencies with technical resources that want to build and run AI reactivation calling in-house with full control over cadence and routing.
#5 Winback Engine — Contact for pricing.
Winback Engine is a reactivation service focused specifically on win-back calling, with published benchmarks and a documented call framework used across fitness, dental, medspa, and service businesses. According to its blog, businesses using trained human agents consistently hit reactivation rates of 25 to 40 percent, versus a 12 percent median for service businesses running any form of win-back campaign. Phone calls from trained agents, the company reports, convert 5 to 10 times better than email because the agent can hear hesitation and address the real objection in real time. The company's four-part call framework is worth knowing about regardless of who runs your calls: a warm opener that disarms the sales reflex, a discovery question to find out why the person stopped coming, a bridge that connects their specific reason to a solution, and a rebook that gets a specific commitment before hanging up. Their guidance also covers segmentation by lapse duration, with 30-day lapses converting at 30 to 45 percent versus 2 to 6 percent for contacts gone a year or more. For a staffing agency, that maps cleanly to clinicians who went quiet 30 to 90 days ago versus truly dormant records. Winback Engine's materials emphasize starting early, segmenting by lapse window, and tracking revenue recovered rather than responses.
Pros
- Documented call framework with word-for-word scripts and objection handling
- Strong emphasis on segmentation by lapse duration, which fits clinician databases well
- Published benchmarks help you set realistic expectations before spending
- Trained human agents consistently outperform automated channels on high-value contacts
Cons
- Pricing isn't published, so budgeting requires a sales conversation
- Primary focus is service businesses like fitness, dental, and medspa, so staffing is an adjacent use case
- Human-agent calling costs more per contact than AI alternatives on large dormant lists
Best for: Healthcare staffing agencies that want a reactivation partner grounded in lapse-window segmentation and a proven human call framework, and that value published benchmarks.
The right win-back partner depends on your list and your team. If you want someone to run the whole thing for you, My AI Call Center stands out for healthcare staffing agencies because it combines managed AI calling with the list discipline this industry needs: consent records checked before launch, TCPA-compliant AI disclosure on every call, and outcomes routed straight into the CRM your recruiters already work in. Calling starts at 9¢ per connected minute with the rate locked for the campaign, no per-seat charges, and a free first campaign review, so you know the full number before approving anything. If human callers matter more to your brand, CallMyCustomers and Upcall are solid managed alternatives, and Winback Engine brings a well-documented call framework. Agencies with engineering resources can build it themselves on Retell AI. Whatever you choose, start with the freshest dormants first. Research consistently shows reactivation odds drop sharply after 90 days, and every week you wait costs you percentage points.

Frequently asked questions
What makes My AI Call Center different from other win-back calling services?
My AI Call Center is a managed service, not software. You buy campaigns that they run for you, each built around one clear goal and quoted in full before launch. The biggest differentiator is list discipline: only approved, permissioned, or reviewed lists get called, list source and consent records are checked before any campaign launches, and bought lists without clear permission records are flagged or declined in most cases. They tell you plainly if the list won't support the campaign before you spend anything. Compliance is built in too, with TCPA treatment of AI voices as artificial voices, AI disclosure on every call, and immediate opt-out handling. Reporting covers only what actually happened, with disposition codes, per-call notes, and DNC logs, and the company states it will never invent client logos, testimonials, metrics, or ratings.
How much does My AI Call Center cost?
Calling starts at 9¢ per connected minute, tiered by volume, and the rate is agreed before launch and doesn't move mid-campaign. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. There are no per-seat charges, no platform bill, and no minimums you didn't choose. The first campaign review is free, so you know the full number before approving anything.
How long should a clinician be dormant before they count as a reactivation target?
It depends on the segment. My AI Call Center's Win-Back & Reactivation campaigns typically target 12 to 24 month dormants, while its Speed-to-Lead follow-up handles fresh leads within minutes. Reactivation research suggests acting earlier converts better: contacts lapsed 30 days or less reactivate at 30 to 45 percent in published benchmarks, versus 2 to 6 percent for contacts gone a year or more. A practical approach for staffing agencies is to segment your database by lapse window and run different campaigns for clinicians quiet 30 to 90 days versus truly long-dormant records.
Are AI reactivation calls to clinicians TCPA-compliant?
It depends on consent, and this is where list discipline matters. The FCC has confirmed that AI-generated voices count as artificial voices under the TCPA, so these calls generally require the called party's prior express consent, with a higher bar of prior express written consent for telemarketing calls to mobile numbers. My AI Call Center treats AI voices as artificial voices under the TCPA, requires prior express consent, honors state-specific quiet hours, provides AI disclosure on every call, and logs opt-outs immediately. Recipients can ask if the call is AI-assisted, request a human, or opt out with keywords like STOP and REVOKE. Campaign requirements vary by location and contact type, and clients are responsible for obtaining appropriate legal guidance before launch.
Do phone calls actually work better than email for reactivating dormant candidates?
Yes, by a wide margin, according to published reactivation research. Winback Engine's benchmarks put phone calls from trained human agents at 25 to 40 percent reactivation rates, versus 2 to 8 percent for email campaigns. The reason is that a live conversation lets the caller find out why the person went quiet and address it in real time, which an email can't do. In iGaming reactivation data cited by Squaretalk, 82 percent of deposits from one 13,000-player reactivation effort followed phone calls. For staffing, a call can surface the real reason a nurse went quiet, whether that's pay, scheduling, or a bad assignment, and route them back to a recruiter immediately.
Can these services work with our existing ATS or CRM?
My AI Call Center routes outcomes, bookings, and follow-up requests back into the CRM and scheduling tools you already run, with hot leads transferred to your team live or landed in your CRM. Retell AI writes call outcomes back to HubSpot, Salesforce, Microsoft Dynamics 365, GoHighLevel, and Zoho. CallMyCustomers works from whatever list you already have, whether that's a CRM, a spreadsheet, or a point-of-sale export, and routes replies directly into your booking process. In every case, expect some list export or integration step on your side before the first campaign launches.
What should we look for when choosing a win-back calling partner?
Start with list and consent review. Old candidate databases often have inconsistent consent records, and a partner that checks consent before dialing protects you from TCPA exposure. Look for transparent pricing quoted before launch, clear opt-out handling, and outcome-based reporting with disposition codes rather than vague activity metrics. Ask whether hot leads route to your recruiters live or land in your CRM, because speed to follow-up drives conversion. Finally, check that the partner segments by lapse duration, since a nurse quiet for 45 days needs a different message than one gone 18 months. My AI Call Center covers all of these, and the free first campaign review is a low-risk way to see whether your list will support the campaign at all.
