[Freeswitch-users] Monstrous Sound Delay, WebRTC, sip-0.6.2, mod_verto

[Алексей kob.kz Целищев]

Hello.
I work with browser with WebRTC with FreeSWITCH Version 1.5.14b+git~20140730T044231Z~b1f382c67e~64bit (git b1f382c 2014-07-30 04:42:31Z 64bit).
Since answer call until the sound is appeared (ICE connection state changed to "connected" in the log) takes ~ 1216ms, which is monstrous for my problems. Have any ideas on this? STUN, as you can see, is disabled.

Nuance: if the operator and the server are in the local network and connected to an internal address, then until the sound appeared goes ~ 280ms, which is a stretch of more or less acceptable. But if I connect to the browser through external network (router with port forwarding), then the delay increases by 5 times.

In that demo with Verto  https://webrtc.freeswitch.org/verto/index.html

How do I configure Freeswitch and javascript app to sound appeared within 200 ms?
