Calls from WebClient to SIP_Endpoint works well and FS manages to reply a 200 OK response, after INVITE from WebClient, with a public IP into SDP.- FS/application="bridge"
- FS run in a EC2 instance.
- WebClient run on Internet.
Audio is bi-directional, all looks good.However, calls originated on SIP_Endpoint to WebClient makes FS to include its private IP into the DSP for any INVITE toward WebClient (B-leg).
I have updated 'tried ext-rtp-ip' to- Public IP address of the instance- private and public STUN services
- auto-natNo matter what I do, I always get
o=FreeSWITCH 1403050916 1403050917 IN IP4 10.10.1.120
c=IN IP4 10.10.1.120At the WebClient side (INVITE). The weird is, using the same profiles in FS, calls from WebClient to SIP_Endpoint have no issues.
Trace in FS (SIP_Endpoint -> WebClient)

----------------------------------------------------------------------------What's is wrong here is c=IN IP4 10.10.1.120 (must be public for RTP traffic between WebClient and FS)
and
a=candidate for public IP is missing (STUN is enabled in FS's profile)Any idea?
