Cause i = 0x82AC - Requested circuit/channel not available

Aug 19 07:57:38: ISDN Se0/1/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x8001

Cause i = 0x82AC - Requested circuit/channel not available

Aug 19 07:57:39: ISDN Se0/1/0:15 Q931: RX <- RELEASE pd = 8 callref = 0x0001

Aug 19 07:57:39: ISDN Se0/1/0:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x80

Any thoughts ??

Re: ISDN channel not available

Hi,

From your debug, your requesting channel 31..

How is your E1 controller configured? Is it configured with timeslots 1 - 31 or 1 - 18?

You can change the order it selects the channels, but that wouldnt be the proper fix.

You want to stop your router selecting channels that arent available :)

Cheers,

Tim
