[asterisk-users] DAHDI congestion problem

[Danny Nicholas]

I've read about this problem a few times with DAHDI.  Since it only takes
about 5 minutes to remake a release of DAHDI, I would keep a release like
2.1.0.4 on hand to fall back on in case this isn't some minor mistake.
DAHDI is still "relatively" new (about 18 months) and this rears it's head
every few tweaks (at least in the forum, perhaps not in real life).

Funny.  The first thing I always do after a reboot is call in from my
cell to make sure things work.  But last night I rebooted and immediately
tried dialing out (with a TDM842B) and got:

WARNING[2720]: app_dial.c:1721 dial_exec_full: Unable to create channel of
type 'DAHDI' (cause 34 - Circuit/channel congestion)

Restarting all of Asterisk or 'dahdi restart' didn't matter.  Neither FXO
card would make an outgoing call until it had received an incoming one.
This with DAHDI 2.2.0.2.
