Turn Your Android Phone into a SIP Phone Place/Recieve Free Calls with Google Voice or Use other voip Service.

Did you know you can turn your phone into a SIP phone with sipDroid?

Sipdroid is an open-source SIP client implemented in Java. The project was based on:

Sipdroid can be used with Asterisk or any other sip phone system, even free systems like Gizmo, or ipKall

I have added my Gizmoproject phone number to my GoogleVoice account, GoogleVoice is currently private beta without invites, so you may want to try ipKall or another cheap voip/sip service.

The nice thing with this setup is it allows you to either use your unlimited data plan or wifi connection to make/recieve calls.

First you need to login to or create an account then find the SIP phone number to add to GoogleVoice:

  1. Sign in to Google Voice.
  2. Go to the Settings link at the top right of the page.
  3. Click the Add/Edit Number link right above your phones, to the right of the page.
  4. Click the Phones tab.
  5. Click Add a new number.
  6. Select Gizmo in the Phone Type drop-down menu.
  7. Enter your SIP number without 1.
  8. Enter a name for that phone, if you want.
  9. Click Save.
Once that is done, click here to download sipdroid, and install that on your Android
SipDroid only works with cupcake/adp roms

Run SipDroid
Press Menu->Settings:

Press Server, and enter:
Then enter your Gizmo login information where Username/Password are
Press Use WLAN, and Use 3g/Edge and leave the other settings alone, press back then you are ready to use Google Voice to place all call :)

Head over to
Make sure gizmo is checked, then go to and input a number in quick call and press call.

Enjoy your free Sip calls without using airtime over 3g or wifi :)

  3. Mobile companies recently rolled out several updates on their software that support Google talk and voice. It's one of the best VOIP services I've been using for several months now.
