• GeoTel Low cost calls and free dial in numbers in Romania.
• GoogleVoice (GV) In order to setup a GV number a verification process is required to check that your IP address lies within the USA. For non US residents the Hot Spot Shield VPN can be run prior to completing the IP check. A pre-existing US number is also required to complete the GV check and a free one can be obtained from IPKall. Once created the GV number in the US area of the user's choice, it can be forwarded from within the GoogleVoice "account/Settings/Phone/Add another Phone" to a free Gizmo5 1-747- SIP number. From within the Gizmo5 account the GV number can be configured in the "Google Voice" settings tab for incoming/outgoing calls. By configuring a SIP device with the Gizmo5 SIP login details incoming/outgoing calls can be completed through the Google Voice/Gizmo5 accounts respectively. Gizmo5 users can then call other GV numbers and other networks for free. The iNum shared numbers can be used for receiving international calls on the same Gizmo5 line as well as the Sipbroker access numbers via the *747 prefix. Fring can be used to configure its associated SIP client with the Gizmo5 login details so that calls can be completed from a pda device over a wi-fi connection. It should be noted that in 2009 Google purchased Gizmo5 and promptly suspended new registrations, however existing Gizmo5 accounts are still usable as of mid-2010, and there are persistent rumors that Google Voice may incorporate Gizmo5 functionality into its offering soon. Also, if you are running FreePBX and Asterisk, there is an article that explains how to use your Google Voice account for free outgoing calls (in addition to incoming) provided you have either a Gizmo5 account or a U.S. DID (from another provider) that you can associate with incoming Google Voice calls.
