Hi All .
Wish u all fine
i have universal gateway AS5400 which is configured H323 ( i couldn't use MGCP ;not supported in CM 4.1)
and know the issue is IE facility Caller ID message cant reach call manager and thus the IP phones cant display the incoming phone number .
we use PRI E1 voice lines .
if there is any way to configure this on the AS5400 H323 gateway it would be a relief . hint its native IOS gateway .
THANKS in advance
