Hello Jan
We are based in Tanzania and the MSC used in Nokia Siemens Rel4 (New) and
the old Siemens Rel99 so it must be ETSI. Is anyway of knowing its
version. I have configured the system to use MTP2. Is there anyway of
putting mtp3=<signaling channel> or it is coming automaticaly when
mtp2=signaling channel?
Here is a trace for one successful call
