If you do not have a SIP phone, there are many softphones
available for Windows, Linux, and Mac OS X desktop PCs, and
there are also SIP apps that run on smartphones. It is beyond the
scope of this guide to review all of the softphones that are
available. However, as a starting point, you may want to
download Linphone (http://www.linphone.org) or Zoiper (http://
www.zoiper.com).
There are also hosted SIP service providers that give you a
landline number which is associated with their SIP servers and
PBXs. You can connect your SIP phone or softphone to these
servers and receive free incoming calls. However, outgoing calls
usually incur charges. Using Google Voice means that you do not
have to pay for outgoing calls to numbers in the US or Canada.
The registration process for Google Voice requires that you give
them a phone number where you can be reached. If you do not
have one then you can get a free number and SIP service that
you can use for the registration.
To do this:
1. Open a web browser and visit http://sip.pregi.net
2. Click Create Account.
3. Complete the registration form (you do not need to
enter a value for the phone number field), and then
click Register.
4. Check your email and confirm the registration.

Submit.
