Issue on PRI line

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 ?

Likely a bug, to tell, the complete trace would be needed.

If you want a stable release, try 12.4(11)XJ4.

12.4(20)T and 12.4(22)T are both very unstable in my experience.

TAC is recommending 12.4(15)T8 at the moment.

But i need a minimum of 12.4(20)T to run srst 4.3/7.0. Cause i'm using 7945, 7965 and 7937G.

So if i downgrade to 12.4(15)T8, my SRST wont work.
