Previously, I showed you how to get free voip with a combo of pbxes, google voice, and some other tools. I since discovered there is an easier way that eliminates pbxes altogether which is described below. Even more recently, I wrote a guide to setting up a high-quality and reliable solution for free home telephone using only Asterisk, an ATA, and Google Talk/Voice.
1.Get a free EKIGA sip address
Sign up for a SIP account with EKIGA here.
2.Get a free IPKALL number
Sign up for a phone number here. Enter your sip account info for the account you registered in step 1.
3.Get or use your google voice account, and set it to forward to your IPKALL number. More detail on this can be found in step 4 of the previous guide.
4.Get the "google voice dialer" (not google voice) and csipsimple apps for android.
In csipsimple, you follow the wizard launched by going to menu -> accounts -> add account -> worldwide providers -> ekiga. It merely requires your ekiga login and password. Now you are ready to receive calls to your IPKALL number (which will ring your ekiga sip address which will ring csipsimple).
To make free outgoing voip calls you need to configure the google voice dialer app with your google voice account info. You can then customize the dialing to select when you want to make your calls with google voice callback to your IPKALL number. Do not dial out with csipsimple through Ekiga itself since it will not work. More detail on google voice callback app use can be found in step 5 of the previous guide (just replace any references to sipdroid with csipsimple as you read).
There you have it. Free voip calling on your android cellphone with a relatively easy setup. Have fun.
Coming soon, I am going to show you how to set up your own Asterisk 1.8+ server and get free high-quality, seamless VOIP at home using only google voice+talk and an analog telephone adapter.
