Hi All, I have one rather
annoying problem...my PBX can work great for weeks, when suddenly I start
receiving these messages when I try to make a zaptel call: Oct 31 13:52:47
NOTICE[15636] app_dial.c: Unable to create channel of type 'ZAP' (cause 34 -
Circuit/channel congestion) Oct 31 13:52:49
NOTICE[15648] channel.c: Unable to request channel ZAP/g1/247 I'm using Sangoma A104
card (with four E1 spans), and these problems are only occurring on the first
two spans (which are connected to a legacy PBX) – the second two spans, which
are connected to the Telco, work perfectly. Even more: when these messages
start to occur, I can hardly initiate any call via problematic two spans (1st and
2nd), where I can with no problem initiate a new call thru the unproblematic
two spans (3rd and 4th). Restart of the Asterisk
is the only cure so far… Does anyone know what
could possibly be the cause, or how could I troubleshot this problem? Regards. Alex |
