I had an issue on a H.323 Cisco 3845 gateway running on c3845-advipservicesk9-mz.124-20.T1.bin.
Today suddenly i couldn't call out through my PRI but was able to call in.
I ran debug isdn q931 and saw this error.
Feb 12 07:44:28.671: ISDN Se0/0/0:15 **ERROR**: call_setup_ack_proceeding: NO HDLC available b channel 30 call id 0x8928
Feb 12 07:44:28.671: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x09A0
Cause i = 0x80A2 - No circuit/channel available
After i rebooted the VG, the problem was gone. Is this a bug ?
What was the root cause of the problem ?
