A first server () includes an alarm interface, receiving alarm notifications () from alarm generating equipment (); a communication interface, transmitting/receiving communications via a communication network (); and a processor. The processor can receive alarm notification(s) via the alarm interface; convert the alarm notification(s) to alarm information; determine recipient(s) corresponding to the alarm notification(s); and, responsive to receipt of the alarm notification(s), transmit communication(s), associated with dispatch call information and alarm information, over the network () to the recipient (). A second server () includes a first communication interface, transmitting/receiving communications via the communication network (); a second communication interface, transmitting/receiving communications via a dispatch network (); and a processor. The processor can receive the communication, e.g., a dispatch call request via the first communication interface; transform the at least one dispatch call request into a dispatch call; and transmit the dispatch call via the second communication interface.

In the present technique, a dispatch call setup determines () whether an auto-reply as a response to a polite dispatch call request is available. If so, a dispatch call blocked using the available auto-reply is sent () as a response to the polite dispatch call request. In response to an impolite dispatch call request being received (), a determination () occurs regarding whether an impolite request is allowed, and if not, the impolite dispatch call request is rejected (). Otherwise, a dispatch call page is sent () to indicate the impolite dispatch call request.

Packets are routed in a data network comprising a wireless mesh network and a controller providing IPv6 management traffic to nodes of the wireless network. A monitor function and a route table manager are used to generate a route table relating IPv6 addresses to each of the nodes via a respective one of a plurality of POP nodes, by accessing a pre-configured topology file, determining the reachability of each of the plurality of POP nodes from the controller by periodically sending test messages from the monitor function to each POP and detecting acknowledgement of the test messages. If a POP node is not reachable, the route table is updated to relate the IPv6 subnet of the POP that is not reachable to the address of a POP node that is reachable. A Layer network is used to direct the IPv6 management traffic according to the amended route table.
