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.
