[Asterisk-Users] T100P Incoming Calls Drop

[Matthew Farley]

I have been experiencing a rather odd issue with my (newly connected)
T100P card. It is installed in my Asterisk server, which is working
great with SIP clients. The card is connected to a channelized T-1 line
(24 channels). The odd bit is that outgoing calls (Asterisk --> T-1 -->
PSTN) works just fine. However, incoming calls (PSTN --> T-1 -->
Asterisk) are dropped after about 20 seconds (the call is fine until it
drops).

     This occurs irregardless of how I handle the incoming call within
Asterisk (playback a message, ring an extension, whatever...). In case
it is related, Asterisk does not see (or perhaps does not recognize) any
DTMF on these incoming calls. My console looks normal for incoming calls
until it says:

== Spawn extension (longdistance, s, 5) exited non-zero on 'Zap/1-1'
  -- Hungup 'Zap/1-1'

Calls that come in from SIP clients (same context, same rules in
extensions.conf) do not experience this problem.

The T-1 is configured as follows:

zaptel.conf:
span=1,1,0,d4,ami
e&m=1-24
loadzone=us
defaultzone=us

zapata.conf:
group => 1
signalling => em_w
language => en
context => longdistance
channel => 1-24
echocancel => yes
rxgain=0.0
txgain=0.0
callerid=asreceived
amaflags=default
busydetect=yes
musiconhold=random


Has anyone else experienced this sort of problem before? Any assistance
that anyone could provide would be greatly appreciated.

Thanks!
