[Asterisk-Users] Random Zap Channel Resets

[Geoff Manning]

Every so often, and it seems that it happens only when a call is in
progress, all 24 Zap channels get reset. All channels are opened and then
timeout. This causes the in-progress calls to terminate.

There are no corresponding Red/Yellow alarms on wither the PBX or Asterisk
although we do receive a fair amount of Blue Alarms.

The Asterisk server is connected to a legacy PBX through a Digium TE110P. 

Here are some configurations:

/etc/zaptel.conf

loadzone        = us
defaultzone     = us

span=1,1,0,d4,ami
e&m=1-24


/etc/asterisk/zapata.conf

[trunkgroups]

[channels]

musiconhold=default

busydetect=1
busycount=7

relaxdtmf=yes
callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
echocancel=yes
echocancelwhenbridged=yes

callgroup=1
pickupgroup=1

rxgain=-5
txgain=3

immediate=yes

signalling=em_w
context=zap-incoming
group = 1
channel => 1-24

Here is the console output of what happens when the channels reset:
