I had been looking around for how to do free VoIP calling on my Droid X. I came across this thread here http://androidforums.com/android-ap...ipgate-gv-app-free-calls-sipsorcery-down.html Apparently this process is outdated and there's a much easier process now. I'm not sure that many people know about this yet. I know it took me a while to find this myself, so I figured I'd post here. Here's the article that explains why the process is easier now and how to do it. http://blog.kylehasegawa.com/google-voice-voip-on-android-just-got-a-lot-easier-with-pbxes-peering Quick Summary of the directions. Get a google voice number and install google voice app. Install sipdroid (free in market) Run sipdroid and click the link at the bottom that says new PBX linked to my google voice Verify your google voice account email is correct and enter your google voice password below (yes, you are giving them your password). Enter your pbxes.org password below that (that's creating a new password, so it can be anything). Click Configure or Save. I don't recall exactly what it says at that step. If you want to be able to receive calls as well, you must have Google Chat enabled on the Google Voice website. Go to google voice->voice settings->phones and make sure you have a google chat account there and that it's enabled for forwarding. Make and Receive VoIP calls using sipdroid. When you make outbound calls, your google voice number will appear as the caller ID. With inbound calls, as long as you have google talk checked off as a forwarding number in google voice and you have sipdroid running, sipdroid will "ring" and you can answer the call over VoIP. Call history will appear in Google Voice AND on pbxes.org (even if sipdroid isn't open). You might also have to check off the 3g option if you want to to work on 3g as well as wifi. I haven't really tested the quality. Would love to see some comments on that. Seems like this would certainly be nice to use if you are overseas with no cell connection, but can get on wifi. Or maybe if you run out of minutes in a month. Could be some security implications here and the need to trust pbxes.org, I suppose.
