Hi all!
I have a question about SIP URI transformation when we call to anywhere in Internet. We have CUCM - Expressway-C - Expressway-E and two domains for internal and external purpose. For exaple, internal.domain and external.domain. When we call inside our network it is Ok, we use internal domain and at remote end we see that call arrive from endpoint in internal domain. But when we call anywhere outside our network we see that call arrive from endpoint with internal SIP URI - name@internal.domain. In SIP trunk configuration we enabled option to send SIP URI of origin system. Is it possible to chenge SIP URI of caller on Expressway-E? How we can change internal.domain on external.domain for external calls?
