Hi,
I have a Nortel Option 11c connected to the telco with a T1. Config on the Nortel is for dms100.
I have placed a RedFone 2xT1 device in-between the Nortel & the outside world.
I am using ‘RedFone compatable’ Asterisk 1.4
There are no errors on the T1 connections & no errors in zttool or within Asterisk. ‘pri show spans’ shows no errors.
Calls to & from the PSTN to Asterisk - no problems.
Calls into the Nortel from the PSTN are in a 4 digit format.
Calls to or from the Nortel result in ‘hangup cause 54’ errors.
I tried using qsig instead of dms100 - no problems until calls are made - then the same errors…
I seem to be experiencing the same error as this guy below - but the final ‘fix’ was not revealed…

I don’t believe this is a RedFone issue - as all the T1 lines appear to be functioning correctly. I believe this is a signalling issue with how Asterisk is communicating with the Nortel - possibly a problem within libpri. Internet reading has shown the Nortel can be very picky.
I have experimented a lot trying to resolve this problem - but it’s seems to be beyold my level of telecoms understanding.
If someone has fixed this issue using paid support - I would be interested in who you used for this & how much it cost. I don’t mind paying to resolve this.
Please find my Asterisk config files below.
Thanks for any help in advance.
