Most likely if DTMF is not recognized on the far end, it would be an incompatibility setting of DTMF support or bug on either UAC and UAS.<br><br>Wireshark trace at both end will help you understand the issue.<br><br><br><div class="gmail_quote">

I see, thank you for explaning. The reason for my concern is, we are sometimes having DTMF issues on outbound calls. It seems when the user (Polycom) enters digits, they are not being recognized by the other end.<br><br><div class="gmail_quote">

What if asterisk sends telephony events that are not in range of 0-15<br>
though?<br>

You are misunderstanding how SDP works; when an SDP offer or answer is sent, that indicates what the sender is willing to *receive*, not what it is going to send.<br>
<br>
If the Sonus device sent "fmtp:101 0-15" in its SDP, then Asterisk should not send 'event 16' events to it. If it does, that's a bug, although standard programming practices would mean that it wouldn't be harmful, it would just be ignored by the Sonus device.<div>
