<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>I’m having some major
conferencing problems with a 3660 running 12.3(7)T4 (was running 12.3(4)T4 and
T7 with same problem) using DSP resources from an NM-HDV. The conference
bridge is configured as an IOS conference bridge in CCM 3.3(2) (old I know,
will be upgrading soon) and transcoders are configured as well as IOS Media
Termination Points. We added PVDMs to 3 different routers in 3 remote
sites to save WAN bandwidth and the quality of their conferences over the WAN
was poor since we didn’t have enough CoS1 in our managed MPLS WAN.
After I added them and configured them at one site conferencing seemed to
work fine when I tested it.</span></font></p>

all. This is what happens:</span></font></p>

style='font-size:10.0pt;font-family:Arial'>I started a conference by calling a
person local at the site and then conferenced in someone over the PSTN.
After hitting Conference the second time that point I could only hear the
person over the PSTN when we were all in the conference. The other local
person I conferenced in could only hear the person over the PSTN as well and
not me. The person over the PSTN could not hear anyone.</span></font></p>
