Telephone is a VoIP program which allows you to make phone calls over the internet. It can be used to call regular phones via any appropriate SIP provider. If your office or home phone works via SIP, you can use that phone number on your Mac anywhere you have decent internet connection.
Telephone's SIP user agent is based on pjsip. You need to build it before building Telephone. Name the directory pjproject and place it near Telephone, in the same parent directory.
$ svn checkout http:https://svn.pjsip.org/repos/pjproject/tags/2.1 pjproject
