<BODY>
We are tracking the following situation:<BR>
<BR>
SIP client connects to our Asterisk server, and then connects to another SIP user. Re-invite is OFF, so Asterisk is in the middle of the whole conversation.<BR>
<BR>
When one SIP client sends DTMF tones, the SIP client uses RFC2833 to send the tones to the server. (This is correct). The server then sends RFC2833 tones out to the other SIP client.<BR>
<BR>
The problem is, the other SIP client is never receiving the RFC2833 packets. An ethereal trace on the same local network shows that the regular conversation UDP packets are coming through just fine (packet length: 172), but the RFC2833 packets are never received on the SIP client LAN (though they are sent by the server). RFC2833 UDP packets appear to be packet length: 16.<BR>
<BR>
Has anyone seeing this kind of behavior, perhaps from firewalls or otherwise?<BR>
