hi ,
i have the mix environment of voice infrastructure, wherein the analog phones are connected to PBX and the IP Phones are registerd to CUCM. There is my VOICE GATEWAY on which my E1 PRI is been terminated. I can successfully dial and call the DID numbers of the IP Phones via PSTN NETWORK---E1PRI---VOICE GATEWAY---H.323 TRUNK---CUCM---IP PHONES.
If i create a n H.323 / SIP trunk between CUCM and EPBX, is it possibe to make a DID call from PSTN to ANALOG PHONES via CUCM?
What should be the preferred protocol H.323 or SIP.
