secondary Message wait alert to DSS key

[Chris Barron]

I think you have understood it but i will expand.
A given user has their sip account and an associated voicemail box. By default message wait from their voicemail box will illuminate the LED at the top of the phone.

However the given user also monitors a colleagues mailbox or a generic mailbox not directly associated with a human user. Typically this is the catchall mailbox for the office.

The requirement is to use a BLF key as a supplementary message wait alert from that mailbox. So A sip notify currently activates the phone MWT LED for the registered SIP account . A sip notify from the secondary mailbox would illuminate a BLF key. It would be nice if a user keypress would interrogate the given mailbox but this is not essential.

There is an alernative solution you might prefer to consider.
Although the phone has only one MWT led status on/off defaulted the mailbox associated to the SIP account. a) The phone config could be set to activate the generic MWT led on reciept of a notifiy from the secondary mailbox (technically we can already do that in the Asterisk setup by associating the secondary MWT) . But the important addition would be to present in the Visual voicemail panel on the phone, the source of the message so the user can select which voicemailbox to interrogate.

We currently have an estate of about 10k Yealink handsets at about 1000 locations. I would estimate that 50% of them would benefit from this feature
