Hi Rene,
I need help on H323 as I am using it to connect two regions eg Site A ( CUCM) and Site B (CME)
1.My problem is that when I call from CUCM to CME the user cant see my Caller ID but I can see if call coming from CME to CUCM.
2. Onother one is, when I call from CME to CUCM there is no ring back tone and the Codec am using G729 as tried few ways but no luck.
