SPA941 new ext will not accept calls

Ext 124 registers(when config’ing the web gui), and can make internal ext calls and outside calls, but cannot accept any call. From internal ext or outside. Nada.

sip show users
says it’s not registering and does not show 124 in the list, even though it makes calls out.

getting my feet wet.
Tried google but did not find any specifics with freepbx and linksys phone on this issue.

Any help on this?

Thanks all.
