    • 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.
    • 描述了一组技术来防止语音信箱长号的问题。 这些技术可以用具有与电信网络的连接的服务代理或其他中间实体来实现。 服务代理可以从订户的家庭网络中的交换机接收来话呼叫。 然后,服务代理可以确定来电的接收方设备在受访网络中漫游。 如果确定订户正在漫游,则服务代理可以联系所访问网络中的远程交换机并且指示所访问网络中的远程交换机在将来电呼叫转发到远程交换机之前禁止延迟呼叫转移。 然后,服务代理可以负责联系用户的家庭网络中的语音邮件服务器,使得用户仍然可以访问语音邮件。
