[cisco-voip] vg224 sanity check

[Ed Leatherman]

Sigh.. They changed their tune, internals work ok. Just offnet are broke. 

I specifically asked them to disable ECM if it got turned on, and suggested they try some normal voice calls using the fax machine to verify that some sort of audio is getting set up

They also say no changes were made to gateway (which I believe cause they prob don't have the login for it) or on their CUCM.

Is any signal conversion happening or DSP's engaged at this point, assuming there aren't any conferencing or such going on?
