OK, I managed to dig up the docs on Feature Group D from the Nortel 
Documentation. And you are right, there is no wink between the ANI 
and called number.

According to the docs, it goes:

Placing a call from 215-555-1234 to 815-555-5678

User: Dials 1-815-555-5678
Nortel: Ring the trunk
Asterisk: Wink
Nortel: Sends ID Field (ANI) KP+00+2155551234+ST (The 00 is 
informational for a normal call)
Nortel: Sends Called Number KP+8155555678+ST
Asterisk: Acknowledgement Wink
Communications Extablished

Now, in the ${EXTEN} variable, what should I see at that point? 
Currently it looks like I am just seeing 8155555678. Would the ANI 
field show up in a different variable?

I am also running into a problem with the calls. I have a very simple 
call plan in place to get this working:

[Context]
exten => _X.,1,Answer()
exten => _X.,2,SayDigits(${EXTEN})
exten => _X.,3,Hangup

Here's what I see on the CLI

     -- Starting simple switch on 'Zap/6-1'
     -- Executing Answer("Zap/6-1", "") in new stack
     -- Executing SayDigits("Zap/6-1", "2063450020") in new stack
     -- Playing 'digits/2' (language 'en')
     -- Hungup 'Zap/6-1'

I never hear the digits read back to me, I get a recorded message 
from the Nortel saying "There is a temporary problem with the Long 
Distance carrier you are calling. blah.blah.blah"

So something isn't taking place that should. Here's my zaptel.conf 
and zapata.conf as well:

Zaptel.conf
span=1,1,1,d4,ami
e&m=1-6
loadzone=us
defaultzone=us

Zapata.conf
[channels]
context=default
signalling=featdmf
usecallerid=no
hidecallerid=no
callwaiting=no
usecallingpres=no
callwaitingcallerid=no
threewaycalling=no
transfer=no
canpark=no
cancallforward=no
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1
immediate=no
context=blah
channel => 1-6
The Feature Group D signaling documentation I have is in PDF format 
if you want to see it.

Thanks for any help!
