[SR-Users] PRACK support in RTPENGINE module?

[Chris Martineau]

Hi,

Trying to use early media with prack support and rtpengine without success.
INVITE(no SDP)-->
183(SDP)<--
PRACK(SDP)-->
200ok(no SDP)<--
ACK(no SDP)-->

Looking at the code it does not seem to allow for PRACK in the methods it supports.

In the rtpengine_manage code...

              if (!(method==METHOD_INVITE || method==METHOD_ACK || method==METHOD_CANCEL
                                           || method==METHOD_BYE || method==METHOD_UPDATE))
                             return -1;

In the rtpengine_answer code...

rtpengine_answer1_f(struct sip_msg *msg, char *str1, char *str2)
{

              if (msg->first_line.type == SIP_REQUEST)
                             if (msg->first_line.u.request.method_value != METHOD_ACK)
                                           return -1;

              return rtpengine_rtpp_set_wrap_fparam(msg, rtpengine_answer_wrap, str1, 2, OP_ANSWER);
}

Returns -1 no matter what function you use.

I have checked code all the way up to 5.3 and on the master.

I may be looking at this wrong and it is supported, but it doesn't look like it.

Could you please advise if this is a oversight or if there is a specific reason it is not included.

Thanks

Chris
