[SR-Users] One sided or no voice issue with websockets

[Gonzalo Gasca]

Hi Kamrul,

Can you provide more details about the call flow:
It is important to understand the following:
-Topology
-Web browser models and versions (Chrome vs FireFox)
-Kamailio version

When you say:
"It works perfectly within local network"
Please take a look at ICE negotiation.

I have sipml5 placing calls to Asterisk via Kamilio working without any
issues.

sipml5 ---> kamailio --> fs --> asterisk
    ------------------ media ------------>

Please provide logs:
sipml5 (java console)
kamailio logs
(If possible browser logs)

-Gonzalo
