Hi Deepak.
It was commented in our last call the dificulties we find here is the retrieval of the location as is not retreived by the WebRTC Gateway but by the Op. Network. In terms of the network location procedures, for a mobile phone is easier as it can be retrieved the Cell the user is connected to, but for a simless device it might not be that simple, I don't know what your plans would be.

Said that for us is okay to perform emergency calls always the location parameter is optional to be retreived

A collaborative document regarding this topic is to be written here feel free to provide comments, content and possible solutions

Update:

Commented at today's meeting, we are holding this feature while we achieve the "stable release" status, once completed, we will focus on this feature.

Regards,
