    摘要: In the present technique, a dispatch call setup determines (508) 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 (512) as a response to the polite dispatch call request. In response to an impolite dispatch call request being received (504, 506), a determination (528) occurs regarding whether an impolite request is allowed, and if not, the impolite dispatch call request is rejected (522). Otherwise, a dispatch call page is sent (534) to indicate the impolite dispatch call request.

    摘要: A method (600,700) and apparatus (800) are arranged and operate for facilitating call routing between sites in an enterprise connected by a private IP network (130). A range of identifiers (220-223) served by IP PBXs (120-123) in the enterprise may be registered with a SIP registrar (212) of an inter-site router (210). Call requests to a communication unit (350) outside the home site are routed to the SIP registrar. A site identifier associated with the destination IP PBX allows the call to be completed by the SIP Proxy or the IP PBX where the call was received. When no private IP network is available, a roaming CU registers with a cellular proxy in the visited network. Calls are routed by when an HLR (340) associated with the CU obtains the roaming number from the cellular proxy (330) in the visited site. The MSC completes the call to the visited IP PBX using the roaming number and a local SIP registrar 440 forwards the call to the CU.

    摘要: An access point (102) conveys (202) to communication units (104) of a plurality of multicast groups, a first indication that the access point supports a method for sending a multicast message. The access point receives (204) a multicast message directed to a receiving one of the plurality of multicast groups, and determines (206) that the communication units belonging to the receiving one of the plurality of multicast groups also support the method. The access point signals (208) a second indication to selectively awaken the communication units belonging to the receiving one of the plurality of multicast groups, and transmits (210) the multicast message to the receiving one of the plurality of multicast groups in a manner that allows (212) at least one communication unit not belonging to the receiving one of the plurality of multicast groups to remain asleep during the transmitting.
