[asterisk-users] Mitel SX-200 + *

[Mark Best]

Jared,
Thanks for the help. 

There are other T1 trunks (using AMI,D4) going to different departments;
however the trunk line talking to the Telco is what it is. 

I do have the ability to change it to ESF, so I will try changing it -
do you suppose my Telco will automaticly adapt if I do? (I'm fairly
confident they support ESF.)

No, but I'll make a few comments anyway.  I'm not sure if they'll help
you at all, but maybe it'll help explain a few things to someone else on
the list.

Is the T1 in alarm?  You've first gotta get it out of alarm before you
can make calls on it.  Alarms are usually caused by physical
connectivity problems, or problems with framing and/or linecoding.

Hmmmn... D4 and B8ZS together?  That's bizarre.  Usually people will use
D4 framing and AMI linecoding together, or ESF framing and B8ZS
linecoding.  I've never seen anyone uuse B8ZS linecoding with D4
framing.
