Official Freephoneline VoIP Unlock Key Guidelines

Post by FONGO_Announcements »

Hi everyone,

We've put together the official configuration settings for Freephoneline VoIP Unlock Key users. These are written to be used with any third party equipment, such as ATAs and softphones.

There are required and recommended settings for VoIP Unlock Key users:
- The recommended suggestions are there to help users traverse firewalls and common home network configurations. Please note that settings may vary depending on your home network setup.
- The required settings are the criteria we will use to follow up with users who are abusing the system.

The most updated configuration settings will always be available here: ... redentials.
You need to be a VoIP Unlock Key owner if you want to use these settings: visit, and select "VoIP Unlock Key" for more information.

Talk freely,

The Fongo Team
