Sip Caller runs on top of 3CX as a cloud remote extension, not a SIP trunk. Calls are placed through your existing 3CX system using your own caller ID, so every outbound campaign is fully automated while staying on the PBX you already own.

Connects over standard SIP and RTP — no custom gateway required
Supports 3CX Pro and Enterprise on cloud, on-premise and hosted
Predictive dialer mode requires the Sip Caller Proxy module on self-hosted 3CX
Your own caller ID, your own 3CX trunks and call costs
Managed entirely from the Sip Caller cloud console

Remote Extension Model

Sip Caller registers as an extension on your 3CX system. No new trunk, no call-forwarding gymnastics, no duplicate billing.

Your Own Caller ID

Outbound calls show your 3CX numbers, so recipients see a familiar caller ID and local presence where needed.

All 3CX Editions

Works on 3CX Pro and Enterprise, whether you run 3CX Hosted, self-hosted on-premise or through a partner.

Predictive Proxy Module

Predictive dialing on self-hosted 3CX uses a lightweight proxy module. Nothing to install for hosted 3CX customers.

Cloud Console

Campaigns, call flows, reports and users all live in the Sip Caller cloud. Your 3CX admin stays untouched.

Local Support

As 3CX distributors in Malta, 4TFront configures the Sip Caller extension on your 3CX system and supports both sides.
