[asterisk-users] T1 signaling configuration

[Ryan Stark]

Hi All,
I'm trying to configure a Digium T100P to talk to a legacy voicemail
system.  I have the signaling specs verbatim from the original manufacturer
documentation as follows:

[T1 Signaling]
Service Type: T1,D4 format, AMI(Super Fram)
Signaling: Four wire, terminated, E&M (Robbed bit)
Start Protocol: Wink start; 250msec duration
Dial Tone: Enabled
Digits: DTMF, 4-digits
DTMF: 50msec duration
Outdial senderized: Yes

[CO Trunk specific order]
DID/DNIS/Phone number group directed to the T1

[Line Hunting]
On in-bound calls the T1 must be configured to do a linear (not circular)
hunt for trunks from 0 to 23. (Try 0 first, then hunt up to 1,2,3,etc)
The voicemail server hunts from trunk 23 down to 0, configuring the T1 as
described above will avoid conflicts.

[Disconnect]
Line should be able to disconnect from either originate or terminate (Need
both: far and near-end disconnect).

[End]

I have in my zaptel.conf:
span=1,0,0,d4,ami
e&m=1-24

and in my zapata.conf:
context=legacybox
signalling=em_w
channel => 1-24

I was trying this on my running system that had zaptel/libpri/asterisk
pre-built, I haven't been using zaptel on there for a while so the libraries
are a little old, zaptel 1.4.5.1 and libpri 1.4.1.  I can make calls to the
machine, it answers and performs regular functions no problem, but when you
try to use the outdial feature from the system it picks up the the line, and
goes to extension s, no digits passed.  If I make it dial my phone directly
when it tries to outdial I hear a quick blip of tone, then silence, then it
disconnects.  I tried switching over to a em instead of em_w signaling in
zapata.conf and I get a warning in asterisk: "ss_thread: getdtmf on channel
24:success" when it tries to dial.

I'm going to build up a test system with a spare TE110P I have spare to play
with this tomorrow instead of using my live system, with the newest
libraries, but maybe this is a signaling issue I'm just not understanding,
something this card can't even do, or something else that I've completely
missed. Any ideas?

Cheers,
-Ryan
