[OpenSIPS-Users] strange behavior with TCP reply port
Hello,
This is on the 3.1.3~20210731~b333a222f-1 from the Debian 3.1-nightly repo.
Typically I run with
modparam("tm", "auto_100trying", 0)
so I can manually send a 100 with
sl_send_reply(100, "Trying");
earlier in the script, before blocking processes like DB lookups and such.
No problem...until today. On a TCP (TLS) connection, the sl_send_reply()
function opens a new TCP socket to the UAC on the IP:port listed in the
original message's Contact, rather than sending the 100 on the existing
socket (using the ephemeral port) the UAC used for its TCP socket to us.
Future downstream replies are relayed back upstream to the ephemeral port.
In other words, only the 100 Trying message from sl_send_reply() is opening
a new socket back upstream.
The auto_100trying option from tm, however, sends its 100 messages to the
ephemeral port of the UAC.
How can I get the sl_send_reply() function to reply on the existing TCP
socket?
Regards,
Jeff

I can't think of a better way of doing either of the SDP editing or replacing logic from the OpenSIPS config file.

Re: [OpenSIPS-Users] Push SDP into Request
Thanks for the replies :)
I am not sure I really understand them, however I have solved the problem
like this:
rtpengine_offer($var(PSTN_TPTY),,$var(SDPbody));
$var(reg) = "/a=silenceSupp.*\n//ig";
$var(SDPbody) = $(var(SDPbody){re.subst,$var(reg)});
remove_body_part();
add_body_part("$var(SDPbody)", "application/sdp")
Perhaps there is a better way but this seems to work for now :)

Re: [OpenSIPS-Users] Push SDP into Request
I noticed that when you manipulate before passing to rtpengine, the module
sends the "old" sdp to rtpengine. Does it make sense?

Re: [OpenSIPS-Users] Push SDP into Request
wouldn't it be better to do first your manip and then pass it to rtpengine
?

[OpenSIPS-Users] Push SDP into Request
Hi everyone
I am using rtpengine_offer() and storing the SDP in a variable which I then
modify using the reg_exp transformation to delete a line.
rtpengine_offer($var(PSTN_TPTY),,$var(SDPbody));
$var(SDPbody) = $(var(SDPbody){re.subst,/a=silenceSupp:off\ -\ -\ -\
-\r\n//g});
How do I then push the resulting variable into the body of the INVITE?
Many thanks
Mark.
