This problem is almost surely a mismatch problem btw the Hicom and the 7206. As mentioned, check the channel search order and bandwidth and ensure that they match on both devices. The channel search order has to be such that there is little probability of the Cisco and Hicom trying to pick the same channel to handle calls they are processing.
I'm not too familiar with Hicom but may be there is some proprietary signalling info that it sends over trunk lines that the 7206 does not understand this could also cause a conflict and resources will not be allocated as and when due.
I have just run into the same problem with a 7206VXR (PA-VXA-1TE1) and Ericsson MD110.
I have also opened a TAC case ( #C859789), and they advised me to set the ascendig bchan-ored. Unfortunately it did not solve my problem...
What I recognized is: I checked the log file and I found controller E1 donw/up messages! It means that the E1 controller restarted in that time, and the outgoing calls failed with that resource unavailable error message. I did a measure with an ISDN tester to find out what could cause the controller restart but I did not see any L1 error. Now I suspect some kind of electrical impact should cause the restart of the Q.Sig (the E1 cable is almost 100meter long and this is a factory!) therefore today I make led the voice gateway to the MD110 as close as possible.
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...
