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 On Wed, Oct 22, 2014 at 9:12 AM, Amit Patkar <a...@avhan.com> wrote: > Please check ICE server settings.
