Detect Device Moves for E911
Device move detection, in support of E911 Emergency Calling Services, is
critical to maintaining the accuracy of Customer Emergency Services ID
(CESID) information. With Release 5.2 and later, the IP device location
can be automatically updated or the location can be monitored for manual
update. Detection of Layer 2 connectivity is through Spanning Tree
Protocol (STP) or Cisco Discovery Protocol (CDP). The Device
Connectivity form excludes Mitel Soft Phones, Symbol, DECT, and
SpectraLink wireless phones, DNIC telephones, CITELlink telephones,
and Hot Desk Users.
Automatic CESID has the following requirements and restrictions:
• All Layer 2 switches must report to CDP or STP or both (use one or
both protocols consistently on all L2 switches in the network)
• Designate Emergency Calls using Route Lists
• Not supported on hubs
• CDP or STP must be enabled on L2 switches
• Automatic CESID will not function during a backup or restore
