Re: [OpenSIPS-Users] PRACK response to 183 without SDP
That's exactly what I suggest! If you remove 100rel from INVITE, the
SIP provider should send a regular 183, not a 183 with 100rel. Then
you can safely drop the 183 without SDP.

Alternatively, you can remove 100rel from the initial INVITE and drop the

Re: [OpenSIPS-Users] PRACK response to 183 without SDP
The call flow is that we (our system) are the caller - we send the first
INVITE. The SIP provider is responding back with 183s because they want to
initiate early media.
Are you suggesting that we remove 100rel from our INVITE that we send out
to the SIP provider?

I can stop the 183 without SDP from being passed on with the following
in onreply_route[]
if ($rs == "183" && !has_body_part("application/sdp")) {
drop();
exit;
}
However, how do I reply back with a PRACK?
Thank you.

Re: [OpenSIPS-Users] PRACK response to 183 without SDP
100rel in the initial INVITE means that the caller has support for it, if
requested by the caller. If not present in INVITE, the caller should not
send provisional replies with 100rel.

Re: [OpenSIPS-Users] PRACK response to 183 without SDP
H Ovidiu
We do not want our system to change to a 'ringing' state, which would
happen if it receives 180. We would like to drop the first 183 (without
SDP) but reply back with an PRACK (since 100rel was sent) and let the
subsequent 183 (with SDP) through. This is just a quirk in our system that
we are looking to find a workaround for.
I don't think removing 100rel from the INVITE would work? The sender of the
INVITE has put in 100rel and is expecting a PRACK, so us removing it does
not change this expectation?
Thank you.

Re: [OpenSIPS-Users] PRACK response to 183 without SDP
Hi Toni,
Thanks, I did come across that.
I was hoping not to have to install a module and have to do even more
changes to accommodate it. I was hoping that there was already a core
feature/mechanism to handle responding back with a PRACK.
Thank you.

Hi,
I guess does not answer the guestion but take a look at this:

that said could you setup b2b logic to fix interworking issues?

[OpenSIPS-Users] PRACK response to 183 without SDP
Hi,,
I have a requirement to stop 183 without SDP packets from being passed, as
well as having to reply back with a PRACK.
I can stop the 183 without SDP from being passed on with the following in
onreply_route[]
if ($rs == "183" && !has_body_part("application/sdp")) {
drop();
exit;
}
However, how do I reply back with a PRACK?
Thank you.
