digium phone does not connect to server DPMA
This is the wrong forum for support questions!
If you have a Digium phone do you not qualify for commercial support from Digium?
I get the impression that DPMA is not open source.
There is no information that would allow anyone to debug the problem.
Nor was there enough information in the other thread that was opened. You’ll need to contact Digium’s support department directly. That’s going to be far more productive than pasting a large number of config files and guessing.
