Executing [EMAIL PROTECTED]:1] Dial("SIP/7533-095aaae0",
"DAHDI/g1/0123456789") in new stack
[Dec 1 09:59:22] WARNING[5011]: app_dial.c:1739 dial_exec_full: Unable to
create channel of type 'DAHDI' (cause 34 - Circuit/channel congestion)
== Everyone is busy/congested at this time (1:0/1/0)
Is there something obvious in configuration keeping this "self-looping
trunk" to work ?
Regards
