A service to connect two callers that are simultaneously leaving a voicemail messages with each other.
This service helps to provide satisfactory call completion to a common voicemail scenario: Party A calls Party B, but get diverted to voicemail and they start to leave a voice message. Party B sees Part A has just called and immediately calls them back – to find that Party B’s line is engaged (because they are still connected to the voicemail system). So Party B gets diverted to Party A’s voicemail.
The service – which may be implemented with IMS/SIP or CAMEL – recognises that the current callers are each trying to call each other (but diverted to voicemail), plays an announcement to the service subscriber and then connects the two parties.
