Abstract: A plurality of public safety answering points (PSAPs) are accessible via a voice-over-packet (VoP) network. A wireless access point of the VoP network is provisioned with a PSAP identifier and/or access point identifier to facilitate the routing of emergency services calls from the wireless access point to the appropriate PSAP. When a mobile node transmits a message to originate a call, the wireless access point parses the message to determine whether the mobile node is requesting an emergency services call. If an emergency call is being requested, the wireless access point inserts the PSAP identifier and/or access point identifier with which it has been provisioned into the message and forwards the modified message to a proxy server. The proxy server receives the modified message and routes the call to the appropriate PSAP, based on the PSAP identifier and/or access point identifier contained therein.

Abstract: A transmitting device may use a determined extent of retransmissions by the transmitting device to a receiving device as a basis to decide on an extent of concatenation of frames of media. In one example, a transmitting device may monitor an extent of retransmissions by the transmitting device to a receiving device during a packet-based real-time media session. The transmitting device may detect a threshold low extent of retransmissions during the packet-based real-time media session. And responsive to detecting the threshold low extent of retransmissions, the transmitting device may increase an extent of concatenation of frames of media during the packet-based real-time media session.
