Hi Richard,   thanks for your input. And i guess you are correct, when reading the sentence with the wording of the SDP RFC in mind attributes should only be „a=“ lines. We will talk to the device vendor again with this new finding!   Anyways, maybe it still makes sense to adjust the SDP parser for such scenarios, as it really doesn’t make sense to require a „c=“ line if the stream is being removed as you said. I will open an git issue aswell.   Mit kommunikativen Grüßen I Best regards   Thomas __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions To unsubscribe send an email to sr-users-leave(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
