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.
