Description (partial)


ViPR call doesn't work via MGCP to H323 GW, but work via H323 GW to MGCP. I make a PSTN call from 2326389 in ViPR client 1 through MGCP GW to back-to-back H323 GW, then to 2326396 ViPR client 2. The call route is learned. I then pull out T1 cable, but ViPR trunk call doesn't work.


MGCP GW goes down and it is not registered to CUCM.
