We have a customer who has a several of huntgroups, each huntgroup has assigned a ddi to ring two different extentions at the same time (one cisco ip phone and one analogue). In tern if the user isn't there this then goes to a third party voicemail server which then translates either extention within the huntgroup to the mailbox number.
When the voicemail server tries to pass mwi information back to the phone this doesn't work. Is this possible via the huntgroup?
The customer is running ccm 4.1.3.
