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

Please check ICE server settings. Your browser may be publishing local IP. One way voice or no voice is typical case when client is behind firewall.

Hi,
We have a setup with sipml5 to kamailio. It works perfectly within local network. In public network the signaling establishes perfectly, but most of the time we hear no voice, sometimes we hear one sided voice and in rare cases we hear voice from both sides. To fix this issue we configured our nathandler like the below: But, still no luck. Any idea how to fix this? Please HELP!!!
