[Freeswitch-users] MWI sent without subscriptions (SIP)

Hi, It appears that FS sends MWI ("message_summary") NOTIFYs to registered devices even tho they do not SUBSCRIBE for it. Some SIP devices (*cough* ZTE *cough*) just don't like MWI NOTIFYs (leds start blinking like a christmas tree before dying miserably), and my workaround to disable those is to set "MWI-Account" to something invalid like: <param name="MWI-Account" value="invalid@invalid.com"/> Is there a better way to disable unsolicited MWI NOTIFYs (without disabling presence)? Thanks, François.
