<DIV></DIV>That's interesting. I had an IP phone user hears echo on calls
to the PSTN issue as well. I tweaked the voice port and had no
success. It got worse like James mentioned before. Then found that
my DSP firmware 4.4.708 had a bug against it. This is what comes with the
12.3.14 T7 IOS (and many other versions I would assume). I upgraded to dsp
firmware 4.4.19 and it fixed my problem.<BR><BR>
