Video endpoints picking up voicemail from OCS
If you want to pick up voicemail from OCS using a SIP video network endpoint rather than using MOC,
this can be achieved by calling the MOC URI with “;opaque=app:voicemail” appended, e.g.
steve.hight@test-customer.com;opaque=app:voicemail
this can be achieved by calling the MOC URI with “;opaque=app:voicemail” appended, e.g.
steve.hight@test-customer.com;opaque=app:voicemail
If the user is a FindMe™ ID (e.g. an OCSRela FindMe™) then this call request will be forked back to
all FindMe™ devices for that ID as well as OCS. OCS voicemail will answer the call and other devices
will display a missed call.
all FindMe™ devices for that ID as well as OCS. OCS voicemail will answer the call and other devices
will display a missed call.
To avoid Cisco VCS forking calls that are aimed for the voicemail system to the FindMe™ ID devices,
a transform should be added to the Cisco VCS: pre-pend the domain portion of the URI with “ocs.” if
the call is for voicemail. This forces the Cisco VCS to route the calls to OCS only.
e.g. (.+)@(test-customer.com;opaque=app:voicemail.*) --> \1@ocs.\2
