3CX Bridge to Unify / Siemens Openscape Business X5

[CornishSteve]

Hey forum users

I've just setup a 3CX phone system in our hosted data centre and would like to create a bridge / sip tie between the 3CX system and our current on premise Unify (Siemens) X5 system.

The on premise PBX is maintained by a 3rd party who charge an extortionate amount per call so before I engage them I was just wondering if anyone has had any success with bridging these 2 systems together before?

When setting up the 3CX system I made sure we used a 4 digit extension base as the on premise PBX has a 3 digit extension base (hopefully this will make the dial plan / routing easier between the systems).

Would be great to hear everyone's experiences

I know it's not exactly what you are asking for, but it may provide some pointers to what you want to do: https://www.3cx.com/docs/

We have working connections between the 3CX and a Siemens DX system, this has an extra PRI trunk card with a link to a Patton gateway on the 3CX side.
