This morning, all of a sudden we were unable to make outbound calls on our PRI. We were still receiving inbound calls just fine. We are using a 2811 gateway. I captured the attached debug isdn q931 output when the problem occurred. I did a shut/no shut on the circuit and the problem cleared. This has happened several times on two different gateways. Sometimes we are not able to make outbound calls, but inbound works. Other times inbound calls are failing but outbound works. Any ideas?
We are using IOS 12.3(14)T6 in our NY location. We are using MGCP. This is a 2811 router. I have attached the config. This problem has occurred several times over the past year. We are also experiencing it at our Zurich site. We are using MGCP and a 2811 router there as well. Our IOS version in Zurich is 12.4(9)T. Thanks.
After those error messages and the restarting of every channel, every outbound call attempt got the invalid channel message. Inbound calls were all working fine. This continued until I did a shut/no shut on the interface. To answer your question, we are not running NFAS. Thanks.
So, we are going to replace the PVDMs and see if that solves it. I don't know. The bug specifically states that ISDN PRI and BRI is not affected because it does not use DSP resources for signaling. But, I will give it a try.
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...
