Some user feedback suggests speakerphone echo perhaps is causing this issue. Anyone know what DTMF signaling mode works best for the Cisco SPA504G ?
Some Google research suggests: RFC2833 is recommended, this is what is set on the extension level.
Perhaps on the PEER side I should also set RFC2833 ?
