If you've heard of IR Heartbeat, StressTest, or "IQ Services" somewhere along the way and can't find a page for it on ir.com, here's what happened: nothing disappeared. It's still here — just organized differently than it used to be.
Heartbeat and StressTest aren't a separate product anymore. They're built into IR Collaborate's testing suite — the same capability, consolidated under one roof instead of sold as standalone tools.
These are three distinct testing capabilities inside IR Collaborate, each answering a different question about your UC and contact center environment.
HeartBeat is outside-in customer experience validation. It accesses and interacts with your UC and contact center systems 24 hours a day, 7 days a week, 365 days a year. Automated calling replicates real customer interactions using real telephony calls, so you know what customers are actually experiencing — not what your internal dashboards assume is happening.
StressTest Premium goes further than component-level checks. It reveals how your system actually performs under stress, with insight into capacity, performance, stability, and resilience before peak traffic finds the gaps for you. StressTest for Video applies the same discipline to video sessions, confirming your systems are ready for peak video load — increasingly the traffic pattern that catches teams out.
WebBeat rounds out the suite with outside-in testing for online communications, so you can confirm your web-based channels meet service expectations with documented, reviewable results.
All four run across the multi-vendor reality most enterprises actually operate in — Microsoft, Cisco, Zoom, Avaya, Poly, and 50-plus platforms — rather than locking you into validating one vendor's stack at a time.
Years ago, HeartBeat and StressTest were marketed as IR's dedicated experience-testing services, sold and referenced somewhat separately from the rest of the Prognosis portfolio. If you came across the "IQ Services" name through a partner, a reseller, or an older sales conversation, that's likely the product generation you encountered.
That standalone framing has since folded into IR Collaborate. The capability didn't get cut — it got consolidated, so testing, monitoring, and observability live in one platform instead of several disconnected tools. If you're used to navigating to a dedicated testing product, the shortest path today is IR Collaborate's Customer Experience Testing page, where HeartBeat, StressTest, and WebBeat now sit together.
This matters most at the moments where assumptions are riskiest: a new deployment going live, a peak season approaching, or a system you're trusting without having validated it outside-in.
Snohomish County Public Utility District No. 1 needed exactly this kind of confidence. Rolling out a new IVR system for 350,000 customers, the team used IR's testing capability to catch issues with SIP trunks, quality of service, and coding before those issues reached a single caller.
"From end-to-end, the experience with IR has been positive — including the bid process, contracting, test setup, and scheduling tests."
— Kristi Sterling, Senior Project Manager, Information Technology Services
Snohomish County PUD No. 1
That's the same HeartBeat and StressTest capability discussed above, applied to a real deployment with real customers on the other end of the call.
If you went looking for "IQ Services" and came up empty, you were looking for a name IR doesn't use anymore — not a capability IR stopped offering. HeartBeat, StressTest, and WebBeat are live, active, and doing the same job they always did, just as part of a more connected platform than before.
