<div dir="ltr"><div><div><div><div><div><div>This is not a direct FreeSWITCH question, but was hoping someone might have set up a similar configuration.<br><br></div>Currently I have a FS server where SIP clients (Linphone) register to via a Cisco AnyConnect VPN.

<br><br></div>If I tunnel all traffic, the SIP transport and RTP media works just fine.<br><br></div>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:<br>
