Figure 26.2 Example of Call Manager Intworking Mode Network Configuration
Survivable Telephony Mode
In an Call Manager Interworking mode, all the calls over VoIP network is
generally controlled by Call Manager. All the originating and terminating calls(IP
Phone or Analog Phone) will not be available if Call Manager fails(e.g., link
failure), or access to Call Manager is not allowable even if Call Manager is
normal. To overcome this failure, the Ubigate iBG3026 continuously monitors the
status of connection to Call Manager; and if a failure is detected, it is
automatically changed to a Survivable Telephony mode where Ubigate iBG3026
can provide basic functions without Call Manager.
In a Survivable Telephony mode, the default call and minimum supplementary
services within the same branch are provided. Depending on the fault type and
settings of Ubigate iBG3026, some calls can be provided to other branch.
