[asterisk-users] PRI Down but zaptel lets calls through

[Michael J. Liberatore]

I havent gotten any responses so i would like to add some more info that
might help someone give me some advice. 
 
At first i thought that the reason it wasnt giving an error or falling
through was because the zaptel status of the wanpipe was OK, but now i
am monitoring that it still doesnt error or fall through even if the
status is RED.  This doesnt make sense to me if zaptel knows its down
then why is it connecting these calls (or thinks it is)
 
here is an example log:
 
[Jan  7 13:22:29] VERBOSE[6160] logger.c:     -- Executing
[5735551815 at from-sip:1] Set("SIP/802-082d2a58", "CALLERI
D(Num)=5735553977") in new stack
[Jan  7 13:22:29] VERBOSE[6160] logger.c:     -- Executing
[5735551815 at from-sip:2] Dial("SIP/802-082d2a58", "ZAP/G1
/19736631815|60") in new stack
[Jan  7 13:22:29] VERBOSE[6160] logger.c:     -- Called G1/15735551815
[Jan  7 13:22:33] VERBOSE[6160] logger.c:     -- Zap/1-1 answered
SIP/802-082d2a58
[Jan  7 13:22:45] VERBOSE[6160] logger.c:     -- Hungup 'Zap/1-1'
[Jan  7 13:22:45] VERBOSE[6160] logger.c:   == Spawn extension
(from-sip, 5735551815, 2) exited non-zero on 'SIP/80
2-082d2a58'


here is the relevant extensions.conf:
$maintrunk is a variable for ZAP/G1
 
exten => _1NXXNXXXXXX,1,Set(CALLERID(Num)=5735553977)
exten => _1NXXNXXXXXX,2,ChanIsAvail(${MAINTRUNK})
exten => _1NXXNXXXXXX,3,Dial(${MAINTRUNK}/${EXTEN},60)
exten => _1NXXNXXXXXX,4,Hangup
 
exten => _1NXXNXXXXXX,103,NoOp(Trying 2nd)
exten => _1NXXNXXXXXX,104,Dial(${SECONDTRUNK}/${EXTEN},60)
exten => _1NXXNXXXXXX,105,Hangup

 
here is zap show status:
 
Description                              Alarms     IRQ        bpviol
CRC4
Wildcard TDM400P REV I Board 1           OK         0          0
0
wanpipe1 card 0                          RED        0          0
0

 
As you can see from the log it never jumps on error to the 2nd trunk.
it actually thinks that the call is going through till it doesnt and the
caller hangs up.  Also i added the chanisavail in the code above after
that log section and it still doesnt work.
 
thanks

Subject: [asterisk-users] PRI Down but zaptel lets calls through


Hi, i am having a problem with my point to point t1, which is being
resolved and is a seperate issue.  sangoma support has been a huge help
and i am waiting on verizon to increase the signal output of the
smartjack.
 
But my issue is that in the meantime my fallover extensions arent
working.  Well they are on the CPE side but not on the NET side.  The
NET side still thinks its making calls, they obviously dont go through,
and they dont return errors.  I tried adding ChanIsAvail hoping that
would detect the line is down but thats not working either.  So
basically i have no way to fail over the calls.  I have the code in
place to have the calls re routed over iax but its just not working
since asterisk thinks the calls are going through until the person hangs
up.  
 
So can anyone help me get this working properly?  There has got to be a
way to have this work, the pri span registers as "Down" so i would think
asterisk would realize it cant make calls over those zap channels,
but...
 
thanks in advance.
 
mike
