VoIP Phones - 3CX PBX

You can our SIP service with your 3CX software PBX as a SIP Trunk.

You can set up the Trunk to register a single number or you can set up the Trunk without registering:

Type: Register/Account based:

Registrar/Server/Gateway Hostname or IP = voiceless.aa.net.uk
Authentication ID (aka SIP User ID) = your phone number
Authentication Password = your SIP password

Type: Do not require - IP Based:

Registrar/Server/Gateway Hostname or IP = voiceless.aa.net.uk
Authentication ID (aka SIP User ID) = your phone number
Authentication Password = your SIP password

The authentication details above will be used when you make outbound calls.

On the A&A Control Pages, you'd want to set a SIP password, and set the number 'To your server via SIP' and enter in the hostname of your 3CX server

If you have additional numbers with A&A, then you can set these numbers to have the "Base/Group" number as your main, trunk, number - and then incoming calls will be routed trhough the same SIP Trunk to your 3CX server. You can then define the Inbound Rules to direct calls to these other numbers to specific locations as you wish.
