[asterisk-users] DAHDI astribank Channel Unavailable

[Kelvin Chan]

Hi guys,

This has been bugging me for days and I can't figure out what's happening.

Using the same channel on DAHDI, I can't make a call after previous one being hung up by remote side. However, it works like it should if my end hangs up the call. To make things interesting, DAHDI, or astribank rather, seems to "reset" itself after receiving an incoming call on that DAHDI channel.

I looked through asterisk as well as kernel logs, didn't find much. Here's some CLI outputs.

Does anybody have some suggestions what might have gone wrong?

================================================
asterisk says:
    -- Executing [311xxxxxxxxxx at 3001-outbound:1] Dial("SIP/3001-00000a02", "DAHDI/31/1xxxxxxxxxx") in new stack
  == Everyone is busy/congested at this time (1:0/0/1)
  -- Auto fallthrough, channel 'SIP/3001-00000a02' status is 'CHANUNAVAIL'
