<p class=MsoPlainText>Hello,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Is it possible to use openSER as TCP <--> UDP
convertor?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I have this working to a certain extent.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>1) UA -> TCP INV -> openSER -> UDP INV ->
Carrier<o:p></o:p></p>
<p class=MsoPlainText>2) UA <- TCP 200 <- openSER <- UDP 200 <-
Carrier<o:p></o:p></p>
<p class=MsoPlainText>3) UA -> TCP ACK -> openSER -> UDP ACK ->
Carrier<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Setup transaction works like it should.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>My question is about subsequent transactions.<o:p></o:p></p>
<p class=MsoPlainText>In the 200 from Carrier (2) a parameter of transport=udp
is set on the contact header.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Now if the UA is running in an automatic protocol mode (
this would be UA specific ), It honors the transport=udp param and sends a BYE
or re-Invite as UDP<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>4) UA -> UDP BYE -> openSER -> UDP BYE ->
Carrier<o:p></o:p></p>
<p class=MsoPlainText>5) UA <- UDP 200 <- openSER <- UDP 200 <-
Carrier<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Is there a way to re-write the transport= param in the
contact header of the 200 ( msg 2 ) so it says transport=tcp Which would then
allow the subsequent request messages from UA to be sent tcp?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Would doing this break the rfc?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Is anyone using openSER to accomplish similar protocol conversion?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks,<o:p></o:p></p>
