Hi Greg,
Our experience is that both Asterisk and Nortel are capable of
understanding DMS100 enough to each be able to connect to a real DMS100
- however neither is capable of actually being a DMS100.
We actually ended up using 2 PRIs between our Nortel 11C and Asterisk -
the first is set up as a tie trunk in the Nortel and uses NI2 on the
Asterisk side. This setup allows us to receive caller ID information
from the Nortel and is used only for calls from the Nortel to Asterisk.
The second PRI is set up as a 5ESS trunk so that the Nortel will accept
caller ID from Asterisk and is used only for calls from Asterisk to the
Nortel.
If you need more specific details, let me know.
Regards,

Hello all,
I have Asterisk 1.2.1 and a TE110P connected to a Nortel Meridian
Option
81C system. The PRI line is currently setup as DMS100. Here are the
relevant lines from zaptel.conf and zapata.conf:
zaptel.conf:
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
loadzone = us
defaultzone = us
zapata.conf:
[channels]
language=en
context=from-internal
musiconhold=default
switchtype=dms100
resetinterval=72000
signalling=pri_net
channel=>1-23
The Asterisk box will see the call setup message, but according to the
d-channel trace (below) a RELEASE(77) message happens shortly after the
CALL PROCEEDING(2) message. The effect is that calls between the two
systems do not happen.
Can someone versed in d-channel messages determine what is going on
here? Also, is there any way to tell the Zaptel card to emulate a
particular release version for DMS100? I believe the Meridian is
expecting Release 36, or something like that (we've tried leaving
Release ID blank on the Meridian side with the same results).
