Hi, All

I have topology collaboration using CUCM and CUBE.

Endpoint - CUCM - CUBE - PSTN.

I tried to calls PSTN number, but i have error 501 not implemented.

Have you see problem sip error 501 not implemented? and how to solve it?

Please help, i attached my debug ccsip message on router. https://pendk.in/TrOg

Advice you to post the debug output in a file directly on the forum instead of on G drive where you would need to request access.
