Why teams pick Allo
3CX is a PBX to deploy and run. Allo turns on in minutes and runs the call from ring to CRM.
Sign up and your phone system is running, no servers, SIP trunks or installs to manage. With 3CX you or an IT partner set up the PBX and its SIP trunks before your first call.

The AI receptionist picks up 24/7, and the moment you hang up Allo drafts the follow-up email or SMS and updates your CRM. On 3CX, AI transcription, summaries and the AI receptionist come with its AI edition.
IVR, intelligent routing, business hours and a mobile app, all in the seat from $32 per user billed annually, with automatic updates and security. The power dialer is an add-on at $50 a month for the whole team. Nothing to patch or babysit.
