Re: [SR-Users] FW: Client site NAT negotiation with no STUN.

Lol, Thanks Daniel! I was concerned my art may get munged, I was using a mobile device to write the original message and was kind of hoping it would have used a monospaced fonts.... go windows phone. Anyway, I've had a look at the change you've suggested, unfortunately it seems to have made little difference and the RTP proxy is still trying to send traffic to the client SIPPhones private ip address and not the firewall. It's probably worth clarifying (seen as the diagram got mangled) that I don't have an RTPproxy at our client site only in our data centre paid with our kamailio. Here's another attempt at the diagram this looks like it's going in munged but we'll see I guess: ------------- -------| RTPproxy |------ --------- --------- | ------------- | ---------- |SIP Phone|--------|Firewall |---------internet-------------| kamailio |-----------|Freeswitch| --------- --------- ------------- ---------- Any other suggestions? -----Original Message----- From: sr-users-bounces(a)lists.sip-router.org [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of Daniel Tryba Sent: 14 February 2014 09:45 To: sr-users(a)lists.sip-router.org Subject: Re: [SR-Users] FW: Client site NAT negotiation with no STUN.

See http://lists.sip-router.org/pipermail/sr-users/2014-February/081601.html for the result as I've seen your art :) I learned to never trust anything a client tells me in a SIP message, forcing all rtp through the rtpproxy only leaves firewall issues at the client IMHO. On an SBC kind of setup just always call rtpproxy_manage() regardless wheter you detect a natted client. In the "default" kamailio.conf just move rtpproxy_manage in the route[NATMANAGE] to the beginning of the route (the f to use the local rtpproxy even if an other rtpproxy is detected) # RTPProxy control route[NATMANAGE] { #!ifdef WITH_NAT rtpproxy_manage("f"); if (is_request()) { .... -- POCOS B.V. - Croy 9c - 5653 LC Eindhoven Telefoon: 040 293 8661 - Fax: 040 293 8658 http://www.pocos.nl/ - http://www.sipo.nl/ K.v.K.
