I thought using data would imply what I meant to say, but I guess I was wrong.

I should also note that when the 200 OK is received from Asterisk, it does not have the double SDP, only after Kamailio forwards the 200 OK does the double appear. -Steve -----Original Message----- From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Wilkins, Steve Sent: Tuesday, October 23, 2018 10:00 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: Re: [SR-Users] Double Session Description Protocol Version (v) 0 data when using rtpengine No calls to fix_nated_sdp(). -----Original Message----- From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Alex Balashov Sent: Tuesday, October 23, 2018 9:58 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: Re: [SR-Users] Double Session Description Protocol Version (v) 0 data when using rtpengine Also, is there any possibility that you are calling fix_nated_sdp() and rtpengine_offer/manage() successively? -- Sent from mobile.

Hi Alex, I just ran a test, and yes, there is an error in the rtpengine log "Error Parsing RTP Header" and there is a double SDP present.

This is usually a symptom of doing a double SDP rewrite, e.g. by making a call to rtpengine twice in the same script iteration, or making a call to rtpengine and then doing some other SDP rewrite operations either before or after that. Cheers On 2018-10-23 21:54, Wilkins, Steve wrote:
