Abstract
A set of techniques are described for preventing the problem of voicemail tromboning. The techniques can be implemented with a service broker or other intermediate entity having a connection to a telecommunications network. The service broker can receive an incoming call from a switch in a home network of the subscriber. The service broker can then determine that a recipient device of the incoming call is roaming in a visited network. If it is determined that the subscriber is roaming, the service broker can contact a remote switch in the visited network and instruct the remote switch in the visited network to disable late call forwarding prior to relaying the incoming call message to the remote switch. The service broker can then be responsible for contacting the voicemail server in the home network of the subscriber so that the subscriber can still have access to voicemail.
