Sam,<br><br>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.<br><br>
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<br><br><br><br><div class="gmail_quote">On Sat, Feb 12, 2011 at 11:50 PM, Muro, Sam <span dir="ltr"><<a href="mailto:research@businesstz.com">research@businesstz.com</a>></span> wrote:<br>

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