I am having an issue of the PRI T-1 circuits going to my VG200 gateways for CallManager going into Lock Out. They connect to a Nortel Opt 81. I can disable and re-enable the D-channels for the circuits and they come back clean. This takes about a week before many channels are locked out again. Is there any way to keep this from happening. I have MCDN checked on the config of the gateway.
Sorry, this isn't a solution, but are you using MGCP? I had a problem with a T1 going to a Nortel - not sure what option. The vg200 was using h323 and everything ws working. Over a break I decided to try mgcp and that's when I ran into the situation that you have. I had 2 vg200s, vg200-1 was local PRI and long distance T1, vg200-2 was local PRI and Nortel T1. It seemed inbound calls worked OK, but outbound from the Nortel T1 would lock the channels. IP phones didn't have a problem going out, but they didn't use the Nortel T1. The phone guy and I played with it for a week and gave up. So we're back to H323 and things are working fine.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
