[AFMUG] Voip analog handoff to PBX

[Nate Burke]

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?
