It seems that the loopback test number was the culprit. I made a call to one of our h320 terminals successfully, however it only bonded 2 channels. When I set up the h320 terminal as an h323 and route the call out the gateway and back in to the other h323 endpoint, all 6 channels on both sides come up. I'm thinking it's an issue with calling BRI lines...one number for two channels. I set up my outgoing called number list with different variations. It only uses one number from the list, so if I put the primary number at the top, it calls the prim again to establish 128K. If I put one of the other BRI numbers in, it calls that BRI number to establish a 64K call -> total 128 w/prim. If I put any other entries in, it never uses it...
index 1 xxxx (only one used)
index 2 xxxy (not used)
and so on...
When I make a call out and back in the gateway, there's only one number (virtual) associated with all the channels...I set it up this way in the Nortel DMS-100. I think that's why it's working that way, but I'm going to perform some more debugs and see what I can find.
