This one I have had to dig for and I am not sure I have found everything yet. Here is what I have so far. The only valid codeset I have found in the documentation for a Definity, so far, is 6. And the only place I have found to set it is in the middle of the first page of the ISDN trunk group, there are two fields for this. I have looked in my R9.2 G3r and an R11 G3r that I have access to. It defaults as a 6 when you create the trunk group.

I would be cautious about making any changes at your end. You indicate that all other long distance traffic completes successfully, if you modify your end you might break everything else. Remember that successful calls also use the same D channel. Any change you make will affect all calls.

I would be curious what your vendor would see in a trace of a good call.

Just for grins, what happens if you send these four numbers out of the non long distance T1s?

I will keep looking.
