I have several 4004's deployed, most into just basic 4 line handsets, or
multiple physical phones. This is the only one going into a PBX, Don't
remember the brand, but it's an appliance with analog handsets. I had
another 4004 going into a Mitel 5000, and it had all kinds of problems
with calls dropping/terminating until I put the Adtran in, it's been
flawless since.
I am using G.711

We're using a 4008, and not seeing this... We are trunking to a
UCM6104 though, which just runs asterisk under the hood.
Is it happening on multiple ports/phones, or just that one?

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?
