Dear Experts

The MWI from a Third Party VM Server which works on the physical handsets does not indicate on the Cisco Jabber Client.

The  VM Server is connected via SIP Trunk to the Cisco CUCM v 10.5.

Any helpful insights is much appreciated.

I thank you for your kind time on this. 

Cheers, MaiSaran
