Sam, You don't need to specify MTP3 for the Dchanel. What MTP2 is just specifying the D channel will be handled on the kernel, rather than user space so it's consider more stable than the dchan option. I see a working MTP and ISUP on your trace, the only part missing is the ANM from the Telco. This looks like a call that was not answered on the TELCO On Sat, Feb 12, 2011 at 11:50 PM, Muro, Sam <research at businesstz.com> wrote: > 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.
