MAINTENANCE
VoIP SERVICES - VoIP CoCPU BOARD
System with a single VoIP CoCPU board
If the VoIP CoCPU board is out of service, none of the VoIP services (H.323 gateway and IP Telephony)
are available.
Resetting the H.323 gateway (VoIP CoCPU board reset) releases all ongoing communications on the
H.323 gateway; reinitializing the IP telephony service resets all the IP Enablers and the communications
in progress on the Multimedia PCs.
Modifying the IP address associated with the VoIP CoCPU board resets the board and all the ongoing
VoIP services.
System with several VoIP CoCPU boards
If the master VoIP CoCPU board is out of service, all the VoIP services (H.323 gateway and IP Telepho-
ny) are temporarily unavailable. The PBX "switches" the VoIP services over to a slave VoIP CoCPU
board: the PBX assigns it the IP address of the faulty board (reference address for the VoIP services:
H.323 gateway, TFTP server, etc.) thereby enabling the VoIP services to be maintained (the number of
possible VoIP communications will however be limited to the number of DSPs remaining).
After replacing the faulty VoIP CoCPU board, it will automatically be assigned the old IP address, which
is now free, of the master VoIP CoCPU board: the new board will be "slave"; the PBX does not return
to the pre-failure configuration.
Nota : It is recommended that the master VoIP CoCPU board of a PBX should be the one that has
the largest number of DSPs. For systems with 2 boards, such as a VoIP CoCPU board with
16 DSPs and a VoIP CoCPU board with 4 DSPs, if the 4-DSP VoIP CoCPU has become the
system master board following a fault affecting the 16-DSP VoIP CoCPU board, then you
should return to the original configuration after replacing the 16-DSP VoIP CoCPU board
by unplugging the 4-DSP VoIP CoCPU board for a few minutes.
If a slave VoIP CoCPU board is out of service, all the VoIP services will be redirected to the master VoIP
CoCPU board. However, the number of possible VoIP communications will be limited to the number
of DSPs remaining.
