We are trying to change our OfficeServ PBX from Bri to Sip-Trunk.

The Provider we are using dos not give us the option to register. What I mean is the connection should work in the other direction:

So not OfficeServe is connecting/registering to the Provider but the Provider wants to register the Trunk in Officeserv.

Thes use hardware that is installed localy that is connecting to Officeserv.

My qustion is, how does this work. What setting i have so put in under 5.2.13 (SIP Carried Oprions) so that not OfficeServe is registering as the Provider but the Provider registers at Officeserv.

For me this sound very particolar but the Provider has only this option and they say they are doing this with several PBX.

We I mean "Register" actualy the provider has both options: with registration and whitout.

Does anyone have an idea if this works with officeserv and what settings i have to put in.

Thank you

Jonas
