摘要 |
<p>Methods for accurate transmission of ELIN/callback number from an emergency caller calling from behind a PBX/MLTS include assigning a port equipment number to each device/trunk of the PBX/MLTS and associating ports/devices with ELINs and callback numbers. The apparatus of the invention detects an emergency number, assigns the call priority, and uses the port/device number to determine the ELIN/callback number and properly transmit the ELIN/callback number over a private network for far-end hop-off to the public network PSAP.</p> |
