[asterisk-users] Zaptel slow dial out - TDM400P

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.
