Maybe vocal components being detected as DTMF. What codec are you using and
what options to you have to use different codecs?

Subject: [AFMUG] Voip analog handoff to PBX
I'm handing off 4 Analog lines to a PBX via a Grandstream GXW4004, and
it's having random cutouts in the audio. The packet stream shows that
it's having DTMF Events that are causing the cutouts, DTMF Tone 'D', so
I"m pretty sure that it's not actually caused by keypresses. I'm
guessing something between the ATA and the PBX there's an incompatibility.
Is there another box quality wise to do 4 Analog lines before jumping
all the way into the Adtran TA904?
Maybe something in like the $300 area?
