We have heard a few reports of our mobile dialers, 1LegCall and ZoneFone, not registering. This issue only effects those with very old versions of 1LegCall and ZoneFone. Versions 1.4 or older may not register.

How to fix: Simply uninstall the old version of the dialer and reinstall the newest version to fix.
