I have a T1 DSS line that uses e&m wink signaling. I have a single digium T100P card.
Using the asterisk/zaptel/libpri 1.0 branch, everything works perfectly.
With the same configs, the 1.2 branch has some very inconsistent problems. Calls outbound on the T1 work perfectly. Calls coming in sometimes work, but often come in with a destination extension of “9” or even a garbled string. In the 1.2.0, they will often come in with no destination at all, with 1.2.1, it comes in with something, but it’s not parsed correctly.
My line does NOT have caller id of any kind. I have tried the configs with caller id feature on and off. I have played with the “immediate” setting along with changing the default em_w timings.
What part of the whole operation is responsible for this and how should I trouble shoot it from here?
