Hi,
I have two CUCM running, one is version5 other is version8.6..By using the same voicegateway (H.323), phones registered to new CUCM unable to communicate both way while in PSTN call. From outside we can hear voice, but from ip phone we heard nothing not even a ringing tone. No issue with internal calls.
VG ip address : 192.168.2.6
old CM : 192.168.2.11 & 12
new CUCM : 192.168.2.21
phone ip address : 10.23.21.0/24
I tried put my ip phone in the same segment as the gateway, the PSTN call works fine.
my dial peer config as per below;
!
dial-peer voice 100 voip

destination-pattern .T
progress_ind setup enable 3
