What does "zap show channels" show?  Are all the channels shown as in
use? What is set in zapata.conf for resetinterval= ? If anything.  I
believe that resetinterval is used to reset unused channels for any
channels that are left open.

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
