Agreed that if the clients gave out the vpn addresses in the SDP, it would be fine. I tried with csipsimple, and it has a whole bunch of useful settings, including "Allow SDP NAT rewrite", which does: *Fix the address sent in the SDP to use the same interface address as the one in the REGISTER request.* Unfortunately Linphone doesn't have a similar setting, so the only way I can see to get it working is to rewrite the SDP in FreeSWITCH. Just need to work out how to do that. On Tue, Sep 10, 2013 at 10:00 PM, Michael Jerris <mike@jerris.com> wrote:
It only makes sense if the endpoints are giving out the vpn addresses as their rtp addresses in the sdp.

My goal is to have SIP and media go over the split tunnel VPN, with the SIP traffic going through FS (which it does) and the RTP stream between the VPN IP addresses of the two endpoints.
I have inbound-bypass-media set to true as I don't want the media to go via FS.
Does that make sense?

are you trying to send the media over the vpn now or peer to peer? do you still have inbound-bypass-media set to true? Peer to peer may never work depending on what is in the original sdp of the clients.

Hi Michael.
I have rtp-ip set to the VPN IP address. Is there any other setting I can try?
Thanks

if your talking about the media still hitting fs but through a different ip that isn't going through VPN, you should be able to work this out by adjusting rtp-ip param

This is not a direct FreeSWITCH question, but was hoping someone might have set up a similar configuration.
Currently I have a FS server where SIP clients (Linphone) register to via a Cisco AnyConnect VPN. I have inbound-bypass-media set to true so that RTP traffic is peer to peer.
If I tunnel all traffic, the SIP transport and RTP media works just fine.
If I set up a VPN split tunnel that allows the subnets of the VPN client and the FS server, the SIP signalling is fine, but in the SDP, it specifies a non VPN address, eg:
INVITE sips:1004@10.1.1.204;transport=udp SIP/2.0 Via: SIP/2.0 10.1.254.36:53036;branch=z9hG4bK.GRrzYXeCN;rport From: <sip:1001@10.1.1.204>;tag=cN83ZcmHw To: sip:1004@10.1.1.204 CSeq: 20 INVITE Call-ID: e7eEYxoML2 Max-Forwards: 70 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO Content-Type: application/sdp Content-Length: 426 User-Agent: LinphoneAndroid/2.1.2-177-g015b83c (belle-sip/0.0.1) Contact: <sip:1001@10.1.254.36:53036

v=0 o=1001 3921 1865 IN IP4 [ISP address] s=Talk c=IN IP4 [ISP address] b=AS:380 t=0 0 m=audio 1031 RTP/SAVP 0 8 100 101 a=rtpmap:100 iLBC/8000 a=fmtp:100 mode=30 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11 a=rtcp:7079 IN IP4 [wireless IP address]
I'm not very familiar with how the SDP is constructed, but I'm
assuming
that it's the SIP client that's responsible for offering it's IP addresses.
Are there any FreeSWITCH settings that would affect the IP addresses in the SDP?
Thanks
Peter
