Pjsip extensions and trunk

A slightly unusual problem, I have five extensions and one trunk set up on a Freepbx 13 system that I have been using for testing. Most trunks and extensions are on chan_sip

I adjusted the trunk so that “Match (Permit)” was set to to allow any connections and then no extensions could register. As soon as I removed the entry all the extensions came back on line.

Any idea why the trunk settings would effect the extensions in that way.

Needs to be

Sorry about that, my typing error, I meant , that is the setting that fails.
