I actually have that running. I configured a sip trunk between fs and cucm 7.1.3.  The trick is avoid sip authentication at all costs. Cucm does not do sip authentication. It can neither accept or register to another sip trunk.

Two things need to be done. First on cucm create a sip trunk to fs using ip address and in your dialplan establish a sip dial route with a prefix like for example 81. So all cisco users who dial 81xxxx will be routed through that trunk to your fs ipaddress.

The other thing that you do is edit your acl to accept everything from your cucm ip address. Then in your dial plan establish another prefix for example for example 71. So all fs users will dial 71xxxx to get to a cucm extension will go directly to xxxx@<cucm ip>.  Let me know if you need additional help.

Good day!

We have next task. We need config SIP trunk between FreeSWITCH and CUCM 7.1. 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". See attachments.

Maybe someone faced with a similar problem?

Thanks,

Anton
