Hello, I'm using the RTPengine with Kamailio and I have a question for a specific case. I have some customer that are changing the source port of the RTP stream during the call ( no re-invite) I think it's more a NAT issue that a user agent issue... I see in the doc that I can handle this case with the "media handover" but in that case the rtpengine will allow a change of the source port but also of the source IP. Any possibility to allow only a change of the source port so source IP must still be the same ? Thanks BR Laurent
