<DIV><SPAN class=500365014-01082009><FONT size=2 face=Arial>I have been having a
strange problem since I configured CUCM7. I have CUCM7.0 running on VMware for
lab testing. I also have a production CUCM 4.3.2 running serving customers. Both
servers are now making calls via H.225 trunks (gatekeeper controlled). There is
no intercluster trunks or any trunks between the two
servers.</FONT></SPAN></DIV>

<DIV><SPAN class=500365014-01082009><FONT size=2 face=Arial>UCM7 is able to make
and received calls without a problem even from UCM4.3. The issue is that UCM7 is
unable to call IP phones registered with UCM4. My test is calling a DID number
that should ring a UCM4 IP phone. What happens is as
follows:</FONT></SPAN></DIV>

<DIV><SPAN class=500365014-01082009><FONT size=2 face=Arial>I have made sure
that the region settings codec are set to g711 on UCM7. What can be the cause of
the problem? Also how can I debug using RTRM?</FONT></SPAN></DIV>
