[SR-Users] where does iceserver configuration get set

Hi List Is ice settings initiaised on the browser side or Kamailio websocket side? Where are the setting parameters created for a=candidate In the debug I get such logs as a=candidate:3164634682 1 tcp 1509957375 xxx.xxx.xxx.xxx 0 typ host generation 0 a=candidate:3164634682 2 tcp 1509957375 xxx.xxx.xxx.xxx 0 typ host generation 0 a=ice-options:google-ice I am connecting with with jssip like the snippet below. There is nothing set for stun/turn. So how then does it use a=ice-options:google-ice. Does it set google as default                 var configuration = {                         ....                         ....                         stun_servers: '',                         turn_servers: null,                         ....                         ....                 };                 // User Agent instance                 var coolPhone = new JsSIP.UA(configuration); Does anyone know are these the only options is relation to ice onfig, stun_servers: turn_servers: null,
