TELEPHONE SYSTEM AND METHOD FOR RELIABLE EMERGENCY SERVICES CALLING
摘要:
A method of routing a telephone call includes receiving an indication, at a handset device 112, to initiate a telephone call. It is then determined, preferably by the handset device 112, whether the telephone call is an emergency services telephone call. If the telephone call is not an emergency services telephone call, it is routed to a proxy server 134. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gateway 116 without first accessing the proxy server 134.
