Communications Manager 220.127.116.11
Grandstream GXP2170 18.104.22.168
Yealink T46G 22.214.171.124
When a mailbox receives a message the MWI is not activated.
If I enable 'Subscribe to MWI' on the phone, MWI will go on, but it will not go off when all the messages have been deleted.
Not consistent at all, Grandstream & Yealink act differently; none with consistency.
Is there a known issue with MWI on this version?
