I have also posted this on the Toshiba Page

Here is the setup. I have a point to point between a Toshiba CiX 5.20 and a Nortel Option Release 3.0. On the Nortel we have a LD T1, so I set up the Toshiba to send LD calls over the T1 to the Nortel. It works, great. However, analog phones on the Toshiba side calling long distance fail about every other call, the digital sets are fine. They get reorder that is coming from the Nortel end.

Whats the difference between a analog set and a digital set when it comes to sending calls over a point to point T1?

:bang:

Have you try your butt-set? Its might be a DTMF problem coming from SL.
