Asterisk IAX2 Trunk SIP Phones no ringback tone

To get the ringback tones working I just had to add these two rules into the Asterisk SIP Settings page in Freepbx.

Right at the bottom you can add custom rules, you need to add:

OSX SSTP Gui Client

Wanting to share this with you guys as its just made my life a whole lot easier!

Zheng Shao over at has pieced together an application using the SSTP-Client open source software for OSX/Linux.

The latest version of the client download link is listed and updated at the top of the page.


Something to note is that this client does not support EAP connections but does support MS-Chap-V2, so you will need to have that enabled to make the connection work.
