I'm having an issue with about 10% of my ougoing calls with Q931 issuing a release_complete message right after I send a SETUP message. Cause code is 0x80A2: no circuit/channel available. Checking with show idsn status I can see that there are plenty of available circuits (also DSPs are available). The fact that we can see a 0x80 in the cause code tells me that it's the router who is unable to get a circuit. The gateway is a 2821 running 12.4(6)T software.
As most calls go through, I suspect that it isn't a configuration issue. The call will succeed after a second attempt.
I have the feeling it might be linked to the fact that we are spoofing the interface. Could it be that layer 2 of the signaling channel doesn't get enough time to come up in order to deal with the request?
Any help or directions would be greatly appreciated.

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
