<br>
I have problem with T.38 and the RTPproxy by one of mine scenarios.<br>
The first one works flawless and looks like that:<br>
<br>
Linksys ATA -> NAT -> OpenSer/RTPproxy -> T.38-GW (Asterisk)<br>
<br>
The second one on the other hand don't work how it should and looks like<br>
this one:<br>
<br>
T.38-GW -> SIP-Proxy -> Openser/RTPproxy -> NAT -> Linksys ATA.<br>
<br>
The normal RTP stream is opened and they switch over to T.38, but the<br>
RTPproxy isn't sending out the received T.38 packets from the ATA.<br>
<br>
If the OpenSER is getting a re-INVITE I call the function<br>
force_rtp_proxy(). I already tried the function with 'l' parameter but<br>
then none of the scenarios are working.<br>
<br>
Why is the RTPproxy not relaying like in the 1st scenario?<br>
<br>
Which flag should I use to get the things working?<br>
<br>
Why is RTPproxy using the same ports like it used for the normal RTP<br>
traffic?<br>
I thought when I call force_rtp_proxy() a 2nd time I create a new<br>
session with different ports?<br>
Can I force the RTPproxy to use different ports?<br>
<br>
If someone needs a PCAP-trace I can provide this.<br>
<br>
Many thanks<br>
<br>
Jens<br>
