month. I use the DSP calculator and do what ever it spits out as far as DSP requirements
but I got to thinking about what it said and did an inventory on some of my
other gateways and now I am stumped. So the specific scenario I have is a VG
that has two PRI’s in it. It has a single PVDM II 48 module. According to
the documentation here <a

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>I can support 48 G.711 channels or 24 G.729 channels. Let’s say I
have the dial-peer configured to use a voice class codec of both G.711 and
G.729 and the regions are set to force G.729. Now I get 24 inbound calls that
are all G.729 will the call fail on the 25<sup>th</sup> call? I always thought the
router would not let you provision the PRI if it could not support all of the channels
with the codec complexity of the voice card but it looks like you can over
subscribe it. <o:p></o:p></span></font></p>
