<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">I
was
ignorant about R2 until I got a someone reuesting to connect a Nec PBX
to an
Asterisk box using the E1 R2 interface (no pri available).<br>
After
several trial and error attempts I was able to build Asterisk 1.6 with
Moises’s
Openr2 library (I had to realize several other things like the fact
that 1.6
only works with Dahdi). Unfortunately I am still having problems and I
hope you can help me. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">For
some
reason when I make calls from the NEC PBX to Asterisk and vice versa
the calls
are not going thru. For incoming calls I see the following messages in
CLI:<o:p></o:p></span></p>
