Having issues with connection to a ISDX.
CUCM5.1---2801 E1 qsig---ISDX
Calls from IP system to ISDX cased phones are OK, when you dial from ISDX side to IPT side get a number unobtainable tone after first 2 digits are dialled.
Anyone got any ideas.

Chances are the pbx is using overlap, debug isdn q931 would show if that's the case.
