I have a call trace of one of these calls...and this seems strange:<div>asterisk sends on INVITE</div><div>a=fmtp:101 0-16</div><div>then 183 Session progress is sent back with:</div><div>a=fmtp:101 0-16</div><div>then asterisk sends 183 Session progress with:</div>
<div>a=fmtp:127 0-16</div><div>OK is sent back with:</div><div>a=fmtp:101 0-16</div><div>then asterisk sends OK with:</div><div>a=fmtp:127 0-16<br><div><br></div><div>Would the above cause DTMF not to be read on remote end?</div>

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.<div><div>

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>
