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 ?

We don't have such a feature right now, but it would be fairly simple to implement. As always, pull requests are welcome of course :)

Cheers
