Hi!

It realy sounds like you want to set bypass-media to false.

> When set, the media (RTP) from the originating endpoint is sent directly to the destination endpoint and vice versa. The signaling (SIP) for both endpoints still goes through FreeSWITCH, but the media is point-to-point.  

If set to true like in your config, media is flowing from the endpoint to the other endpoint which is much more harder for any firewall or NAT in it's way.
Also many carriers block RTP flows from IPs other than the SIP registration, which also results in the same problem.

Kind regards
Kevin

Hi, I have the following environment :


FS (ethernet interface with public address -190.64.204.60) ---- FW (provider) ------------- INTERNET ---- Router --NAT/FW----LAN Softphone (type A)
                                     INTERNET ---- Mobile network ---- Softpone (type B)
Freeswitch v1.6.20, on Centos 7, behind a firewall, with sip ports tcp/udp 5560 already opened, and it is not natting.
I have two type of SIP devices: 
Type A) connected to a LAN behind a router/firewall, natted and with upnp enabled 
Type B) connected through the mobile network, also natted. 

Calls (audio / video) between two A endpoints  works!, but calls between A and B endpoints are established, but there is no audio / video, and after 30 seconds it hungup. I'am using FS for SIP signaling, and bypassing media. I tried many softphones (Linphone, antisip, and more) without luck. Also enable stun at both softphones, but I have the same result.

FS is not using nat functionality (no UPNP/PMP).
I have just one sip profile (external) with port 5560.

I'am attaching the configuration. I suppose it's something related to RTP and NAT but I tried many configurations, and can't resolve it.
Thanks a lot for your help!.
Regards,
                 Anacelia
