The problems Aircall users report
Call context and history trapped inside the dialer — 38 complaints about Aircall; 45 complaints across 3 products · market pageUsers across multiple AI sales dialers can't access the information they need — call history, transcripts, CRM contact context, voicemails — without jumping between apps, logging into a separate website, or manually counting records. Specific complaints include being unable to search the 'All Calls' menu, having to manually count calls made in a day, needing to follow a separate link just to get a call recording, and transcripts never making it into CRM notes automatically. The friction isn't one missing button; it's that the record of what happened on a call is scattered across the dialer, the CRM, and email — and stitching them together is left entirely to the rep.
VoIP client instability during live sales calls — 30 complaints about Aircall; 30 complaints across 1 product · market pageAircall regularly drops calls, freezes, glitches when used alongside HubSpot or Front, loses Bluetooth headset connections, and stops working entirely after PC hibernation or system updates. Reps describe having to sign out and back in, reload the entire browser window, or fall back to their personal phone number mid-shift. The failures hit hardest during active calls — the exact moment reliability matters most.
Unpredictable VoIP call quality for sales teams — 27 complaints about Aircall; 30 complaints across 2 products · market pageSales agents and their managers report calls that are choppy, drop mid-conversation, echo badly, or cut out entirely — often on international calls or for teams outside North America. Multiple users describe the problem as recurring weekly, with one noting 'the system fails at least twice a week and call recording quality is poor,' and others reporting agents 'unable to hear the lead' or calls connecting to the wrong numbers. The problem isn't a one-time outage; it's a persistent, unpredictable degradation that erodes rep productivity and customer trust.
Billing traps and unreachable support after purchase — 25 complaints about Aircall; 31 complaints across 4 products · market pageUsers across multiple AI sales assistant products describe being locked into contracts they can't exit, charged for services they couldn't use, and left with no real recourse — just ticket queues, templated replies, and offshore reps who can't escalate. Specific complaints include losing $10,000 after a training delay with no refund path, being billed for a full year after advance cancellation notice, and paying $120 for a feature that wasn't available for days with a refusal to refund. The pattern is consistent: support becomes a wall specifically when money is at stake.
Call state chaos blocking agents mid-workflow — 24 complaints about Aircall; 35 complaints across 2 products · market pageAgents constantly lose work or get stuck because the software doesn't manage competing call states cleanly. Notes get auto-saved or wiped mid-entry when a new call arrives, outbound calls end inbound ones, transfers generate duplicate tickets or silently fail with no confirmation, and the after-call work window disappears without warning. The system treats each call as isolated, so anything happening between calls — note-taking, rating, queuing a callback — is a fragile no-man's-land.
VoIP call quality tied to internet stability — 22 complaints about Aircall; 22 complaints across 1 product · market pageSales reps using Aircall report that call quality degrades sharply whenever their internet connection dips — voices break up, calls drop, or latency spikes even on what registers as a strong connection. Multiple users note it 'totally depends on the internet' and that the bandwidth requirements are impractical for anyone working in the field or in offices with inconsistent WiFi. The core frustration is that a dropped or garbled call during a live sales conversation has immediate, concrete business consequences — lost deals, missed follow-up details, and damaged first impressions.
Audio device switching breaks sales calls — 16 complaints about Aircall; 19 complaints across 2 products · market pageSales reps using browser-based and desktop calling software lose audio mid-shift whenever a headset disconnects, gets plugged in late, or switches between wired and Bluetooth — requiring app restarts or even full computer reboots to recover. Complaints range from 'I have to restart my computer at least once a day because my audio goes out' to AirPods requiring a manual device change every single call to 'the software bugs you about permissions instead of just using another headset.' The software never remembers a preferred device, never recovers gracefully, and never fails silently — it just breaks the call.
Phone number routing and dialer reliability failures — 15 complaints about Aircall; 23 complaints across 3 products · market pageUsers are routinely connected to wrong numbers, see incorrect caller IDs on the recipient's side, and lose track of which number they're calling from — sometimes mid-call. Specific complaints include calls being routed to 'incorrect numbers when dialing,' caller ID not syncing with the database, numbers being swapped between consultants' outbound calls, and reps having to call themselves just to verify their number isn't flagged as spam. The dialer itself misbehaves enough that redialing and multi-click workarounds are a daily routine.
Chronic lag during active sales shifts — 15 complaints about Aircall; 19 complaints across 2 products · market pageUsers across both Aircall and Aloware report consistent slowdowns, white screens, and choppiness — especially during long shifts. Several note the app needs to be restarted mid-day, and at least one user reported it getting 'very laggy' after 8 hours of continuous use. The problem is persistent enough that users have learned to distinguish between 'network lag' and 'software lag', meaning they've already ruled out their own internet as the cause.
VoIP call audio quality failures — 15 complaints about Aircall; 19 complaints across 2 products · market pageSales reps using browser-based and mobile VoIP tools consistently report that customers can't hear them clearly, or vice versa — complaints include sounding 'underwater', audio cutting out after two minutes on mobile, echo, background noise bleed, and intermittent line 'grizzling'. The problem hits both sides of the call, meaning reps often don't know there's an issue until the customer says something or hangs up.
