Support of Telefonica Germany (O2) multi-service router

[1ama]

Hi,

we have an OneAccess One425 multi-service router from our provider (O2) that realizes a so called All-IP connection.

Does anybody know if that scenario is supported by the 3CX PBX?

Thanks a lot.

The device appears to support analogue telephone circuits. Are you planning on using these through a service from your provider? If so, then the ports normally used by 3CX may be reserved for those services and unavailable for 3CX . It may depend on the configuration options in the device.

Ok, for anyone who will have same question one day: It is supported.

Just "Add SIP Trunk", select Generic:



and enter your provider creds, where Registrar is the OneAccess425:



For us, luckily no further configuration was required.
