How we picked
Voice is the channel where helpdesk vendors most often ship a checkbox rather than a product. Plenty of platforms will let you attach a phone number and log a call. Far fewer give you the things that make a phone queue survivable: an IVR you can edit without a support ticket, skills-based routing with real overflow rules, queue callback so customers don't hold, call recording with retention controls, and reporting that puts calls in the same dashboard as email and chat rather than a separate tab with different definitions. We picked on that operational depth.
The other axis is whether voice shares state with the rest of the desk. The whole argument for helpdesk-native telephony is that a caller's history — last week's email, yesterday's chat, their open order — is on the agent's screen before they say hello, and that the call becomes part of the same record afterward. Gladly is the most committed to this model, building around one continuous customer conversation across channels rather than a series of discrete tickets, which is why it costs what it does and why it's the right answer for high-value B2C brands and wrong for a cost-per-contact operation. Dixa takes a similar unified-queue approach at roughly a quarter of the price and is aimed squarely at retail and ecommerce.
At the other end, LiveAgent is here because a genuinely usable built-in call center at $15/agent/mo is an outlier in this category — it undercuts platforms costing four times as much on the basic voice feature set, and for a small team adding phone to an existing chat and ticket workflow it's the obvious starting point. Sobot deserves attention for the same reason at contact-center scale: comparable omnichannel voice capability at a price meaningfully below Western competitors, which matters most for teams with high volume and thin margins. Sprinklr Service is the enterprise pick when you need 30+ channels and global routing governance.
What to prioritize
- A full telephony quote at your real minute volume and country mix. Seat price is the small number. Get number rental, per-minute inbound and outbound by country, recording storage, and transcription costs in writing, modeled at your projected volume. Teams routinely discover post-signature that telephony doubles the bill.
- Queue callback, not hold music. Letting a caller keep their place and receive a call back is the single highest-impact feature for CSAT in a phone queue, and it reduces abandonment more than adding agents. Confirm it exists, works across business-hours boundaries, and doesn't require an enterprise tier.
- An IVR you can edit yourself. You will change the menu — for a product launch, an outage, a holiday. If that requires a professional-services ticket and a two-week turnaround, your IVR will be permanently out of date. Build a three-level tree during the trial and time how long it takes.
- Screen pop with the caller's full history before the agent answers. This is the entire reason to buy voice inside a helpdesk. Test it with a known customer number and check what appears: identity, open tickets, recent orders, and prior calls, or just a phone number. If it's just a number, you've bought a phone system that happens to sit next to a helpdesk.
- Recording, retention, and consent controls that match your jurisdiction. Two-party consent states and most of Europe require disclosure, and PCI requires pausing recording around card entry. Confirm automatic announcements, mid-call pause and resume, configurable retention, and deletion on request. Getting this wrong is a legal exposure, not a feature gap.
- Unified reporting across voice and digital. Handle time, first contact resolution, and CSAT must be comparable across channels in one place. If voice metrics live in a separate telephony dashboard with different definitions, you'll never be able to answer whether moving volume from phone to chat actually helped, which is the main strategic question this data exists to settle.
