Hi,

Trying to use early media with prack support and rtpengine without success.

INVITE(no SDP)à

183(SDP)ß

PRACK(SDP)à

200ok(no SDP)ß

ACK(no SDP)à

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
