[cisco-voip] Intermittent call failure on QSIG trunk

[Sechaba Mokoena]

Hi,

I have a 3825 router connected to a Siemens HiPath PABX with a QSIG. My
Cisco IP Phones place calls to the PSTN though the QSIG trunk. I've been
having intermittent errors with placing calls through the trunk, and I've
picked up the following error through debugs:

**ERROR**: CCPMSG_OutCall: fails with cause 0x22
Cause i = 0x80A2 - No circuit/channel available

I don't think its over utilization, I checked the channels in use and only a
third were active. Does anyone know what could be causing this.

Kind regards,

Sechaba Mokoena
