Purchasing Agent commented on ASTERISK-27821:
---------------------------------------------
Hi Richard, thank you for your investigation to this matter. Your solution of changing MWI Subscription Type to Solicited from the FreePBX default of Auto did the trick. The PJSIP extensions have stopped loosing registration and that includes when our MOH server is not running.
Thanks again!
