CUCM SIP Trunk with authorization

[Yankovskyi]

Good day!

We have next task. We need config SIP trunk between CUCM 7.1 and third-party system (freeswitch).

There is a caveat. Freeswitch can only use SIP trunk with authorization. Freeswitch have to register on CUCM.

We have made in CUCM SIP trunk with correct SIP Trunk Security Profile for authorization and created Application User.

But freeswitch can not registered. There is 405 error "SIP trunk disallow REGISTER".

Maybe someone faced with a similar problem?

In what could be the reason?

Thanks,

Alex

Thanks for you response.

If I understand correctly, I need config SIP Realm, when I want register freeswitch on CUCM?

According to the documentation yes. You need to  configure digest authentication for this I believe

Yes, we have configured as written in guide. But we get this message in freeswitch:
