Thanks Henry, Volume was the only thing that made a difference; reduced the frequency of occurrence, however did not eliminate the problem.
I think I'll rip it out.

I can't remember if you can control the volume level but if you can turn it down (-6db)and try again. Set the FXO ports to 600 ohms & 2.15 uf Set-up asterisk to answer after 2 or 3 sec delay (one or two rings) If you have this set up as a SIP trunk then make sure dtmf signaling is default to RFC2833 and codec is PCMU (only) If this doesn't work then it may need replacing. ================================= Henry L.Coleman [www.VoIP-PBX.ca] Tel: 647-723-5160 Ext.203 ================================= { Doug Geary} > New implementation, 3 POTS lines into a Grandstream GXW4104, about 20% > of the time, when the IVR picks up, the caller hears a "Bzzzzzt" and > then the IVR starts.
