I am getting random busy signals which I believe is related to a 'glare' condition where the router tries to use the same channel. I have found that you should order the PBX and VoIP peer opposite (top down and bottom up) but I have not found how to actually do this.
The error I get is:
*Sep 10 18:36:19.491: //2848/2F75B4C39568/CCAPI/cc_api_call_disconnected:
Cause Value=44, Interface=0x4762E32C, Call Id=2848
*Sep 10 18:36:19.491: //2848/2F75B4C39568/CCAPI/cc_api_call_disconnected:
Call Entry(Responsed=TRUE, Cause Value=44, Retry Count=0)
Solved! Go to Solution.

Hello Bill
Under the D channel interface (serial x/x/x:23) try the following:
isdn bchan-number-order [ascending | descending]
Hope that helped, if so please rate.

If this is a T1 CAS circuit, the issue might be caused if the time it takes for a wink to come back to the router after seizure is different from the wink duration timer.
If this is the case, the use of the 'timing wink-duration receive

It is a PBX that is linking into the router, and the router is handling site-to-site calls. The busy signal is happening from a call destined for the second site (VoIP peer on the dial plan).
Here is the hardware:

I'll post the full vpm & vtsp output as soon as I can capture an issue.

I think this may have done the trick ... I set the wink-d value to 250 to start, and everything broke, so I went down a bit to 180 and everything seems to be stable now. Submit one more reply if you can so that I can give you credit for 'resolving' the issue if everything holds.
