[asterisk-users] Zaptel slow dial out - TDM400P

[Ken Williams]

So, I updated to 1.4.12 last night and it appears my problem is mostly
gone now.  Not sure what the difference was, but it now takes about 3
seconds before the ZAP line picks it up.  I was on 1.4.10.1 before that,
and yes POTS.  Removing the echo cancellation at this point makes no
difference, not sure if it would've pre-.12.  
 
I'm leaving the 'r' in the dial statement as 3 seconds is kind of an
awkward amount of time for a dialtone after you hit dial, but I could
remove it and it wouldn't be the end of the world.

Below is a copy of my log, zapata.conf & extensions.conf that relate to
the ZAP lines.  Basically when we dial out it takes on 10-12 seconds
before the ZAP line actaully picks up.  I'm hoping to find out what the
cause is for this as it's causing user grief with extremely long connect
times, and I believe it may be causing issues of cross lines (an
outgoing call gets mixed with an incoming call, both ending up on the
same line).  Incoming calls are processed fairly quickly, about 3
seconds which is perfectly acceptable.

EXTENSIONS.CONF
 
        TRUNK_OPTIONS=rTt ;r here because of the 10-12 second delay
        exten =>
_1NXXNXXXXXX,1,Dial(ZAP/2/${EXTEN},120,${TRUNK_OPTIONS})
        exten =>
_1NXXNXXXXXX,n,Dial(ZAP/3/${EXTEN},120,${TRUNK_OPTIONS})
        exten =>
_1NXXNXXXXXX,n,Dial(ZAP/4/${EXTEN},120,${TRUNK_OPTIONS})
        exten => _1NXXNXXXXXX,n,Hangup()

---------------------------
Note that my extensions.conf  used to have a single line exten =>
_1NXXNXXXXXX,1,Dial(ZAP/g0/${EXTEN},120,${TRUNK_OPTIONS}) but I changed
it to see if this way sped things up at all, it doesn't.
 
Any suggestions would be greatly appreciated.
