thanks for the pointer.
The SPA-3012 is pretty strong on configuration options, but the documentation is very light on what they actually mean. Just so that I know, what is AVT actually doing ?
regards Dave
DTMF Tx Method Select the method to transmit DTMF signals to the far end: InBand, AVT, INFO, Auto, InBand+INFO, or AVT+INFO. InBand sends DTMF using the audio path. AVT sends DTMF as eypents. INFO uses the SIP INFO method. Auto uses InBand or AVT based on the outcome of codec negotiation. The default is Auto.

You should check it out if you haven't already. gs
