Current FS requires proxy media if you use zrtp and exist NAT in media path. On Tue, Jun 28, 2016, 17:35 Ken Rice <krice@freeswitch.org> wrote:

Hello,

Is it possible to make freeswitch relay the 180 or 183 replies, including the ringback tone, in proxy_media mode to the next hop?

I've enabled inbound-late-negotiation in the sip_profile and here is my dialplan config: <param name="inbound-bypass-media" value="false"/> <param name="inbound-proxy-media" value="true"/> <param name="inbound-late-negotiation" value="true"/> For now I've set the ring_ready, else no ring back tone is generated.
