I am not 100% sure if the title is correct.
What I want to do it this: I have a cellphone (Nokia N900) which has direct support for SIP account, and I want to make calls using google voice with it. So the task is to bridge the cellphone and GV.
I have found this website which will do the task,
https://simonics.com/gvgw/#faq1basically, if u provide it with your google account info, the site will give you a SIP account directing calls to/from GV. The site doesn't look it will last long, so I am a little reluctant to use it.
I have an Obihai 110 myself, since it works like a SIP gateway for GV. I wonder if I can obtain the SIP settings somewhere to use it on my cellphone. (like username, pw, outbound proxy, port, etc.)
Thanks for any related info.
