I am making test call from IMSDroid(<a href="https://github.com/DoubangoTelecom/imsdroid" id="yui_3_16_0_ym19_1_1479789256850_5186">https://github.com/DoubangoTelecom/imsdroid</a>)
android client to SIPML5 client( i.e <a href="https://www.doubango.org/sipml5/call.htm" id="yui_3_16_0_ym19_1_1479789256850_5187">https://www.doubango.org/sipml5/call.htm#</a>)
. When both are in the same wifi call is working. But when my android phone is
on 3g and SIPML5 client is on wifi, call is established but voice is not
audible. Can you please help us what is the issue and how to fix. My Freeswitch
server is natted to a public IP.</div><div id="yui_3_16_0_ym19_1_1479789256850_5188"><o:p id="yui_3_16_0_ym19_1_1479789256850_5189"> </o:p></div><div id="yui_3_16_0_ym19_1_1479789256850_5190"><b id="yui_3_16_0_ym19_1_1479789256850_5191">Following is the invite going from my android client.
