I am the switch administrator for a large campus based 8710 platform Avaya PBX running CM 4.0. Our subscribers are located across several multi-level buildings, in perimeter office spaces and cubicles. Policy allows the users to log-off their assigned IP phones and onto other available IP phones in other areas of the building in some cases. This creates a potential problem with locating a 911 caller since the PSAP receives only 10-digit ANI based on the caller's extension number. I hear rumors that Cisco has a workaround for this issue with their Call Manager VoIP system. Are there any workarounds for the Avaya VoIP solution? Possibly phone set MAC-address based location? Any ideas would be appreciated!
