Doktor,
Thanks for the commands but i'm not quite there. I've got 16 analog lines between the md and octel. If i initiate a trace it will be difficult to know which line/port octel will use talking to the md to trace. What i'm actually trying to investigate is, I call a number which has a diversion to sdm in octel. Octel is suppose to call a number in info table index 6 but goes into a loop. I have to trace why md is not accepting the number. If i dial the same number in the pbx its works fine. This is a mistery!
