VVX 500 MWI does not work

MWI works just fine for the IP650, why doesn't it work for the same configuration (same account) on a VVX 500?

Re: VVX 500 MWI does not work

Hello plaurent,

it is always useful if users state the current software version of the device they are having issues with.


I am not aware of any open bug's with MWI but would suggest that you check the current UCS 4.0.2 Rev B release notes against your own software in order to check if you can find an open ticket.


You could also use a script like this => here <=


Above 3rd Party script sends MWI On or Off to a phone.


If you are still unable to get this working I strongly suggest to contact your Polycom reseller to raise a Ticket with Polycom Support.


Please provide them with a Wireshark trace for both Phones and the configuration you have used and the <mac>-app.log and <mac>-boot.log.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
