Calling Numbers in Your Contact List

Instead of manually entering the number into the dialer, you can call numbers in your contact list using SIP. Note that if the number is not a toll-free number you will need credit in your Gizmo5 account. In your contact list, tap the desired contact to bring up the details. For each phone number the contact has, you will have both a Call and a Text option. In order to perform the call with SIP, tap the

Text option

. A menu will pop up with three options (possibly more if you have third party SMS apps or the official GV app installed)-- Messaging, Phone Call, and Sipdroid. Select Sipdroid and Sipdroid should perform the call.

The Relationship Between Gizmo5, GV, and the PSTN

This section should help you understand the relationships between Gizmo5, GV, and the PSTN. Let's assume you have a friend who, like you, has a SIP setup using Sipdroid, Gizmo5 and GV. In your contact info for him/her, you have your friend's actual cellular number, GV number, and SIP number.

If you tap on your friend's cellular number...

...and choose the Phone Call option, the call will be connected on both ends using cellular voice. No one will be using SIP, and both people will have cellular minutes deducted.

...and choose the Sipdroid option, the call will be connected on your end using SIP to Gizmo5, which will then route it out to the PSTN and connect to your friend via cellular voice. Your friend will have cell minutes deducted, and you will have Gizmo5 credits deducted.
​

If you tap on your friend's Google Voice number...

...and choose the Phone Call option, the call will be connected on your end using cellular voice, which will route it over the PSTN to Google Voice, which forwards the call to your friend's Gizmo5 and then via SIP onto his/her phone. Your friend will receive the call for free, and you will have cellular minutes deducted.

...and choose the Sipdroid option, the call will be connected on your end using SIP to Gizmo5, which will then route it out via PSTN to GV, which will then route it using SIP to your friend's Gizmo5. Your friend will receive the call for free, and you will have Gizmo5 credits deducted.
​

If you tap on your friend's SIP number...

...and choose the Phone Call option, the call will not connect and neither side will be billed.

...and choose the Sipdroid option, the call will be connected on both ends using SIP. The entire call will occur over SIP and thus neither side will have cellular minutes or Gizmo5 credits deducted.​

Extra Credit: Free Outbound Calling Via Google Voice

I mentioned earlier that it is possible to make some non-toll-free outbound calls using Google Voice. Google Voice provides free outbound calling to any number within the United States and Canada. This is possible to do with SIP, but the service requires Google Voice to perform the dialing. Normally when performed in the official Google Voice app, this process is transparent. However, the official GV app does not support SIP dialing. In order to perform the call then, you must open the Google Voice webpage in your Android browser and perform a callback. Scroll to the bottom of the webpage, enter the number you wish to call, and click Call. If all is working properly, your phone should receive a SIP call. Answer this call and the number you called should be connected on the other end shortly.
