resides on the same server as the Primary VCX Network Call Processor
(NCP).
■
Alternate Server IP Address — Specifies a second location from
which a telephone can receive its download. Typically, this is the IP
address of the Secondary VCX NCP in a dual-server configuration.
■
Voice VLAN Configuration — If you configure any of your 3Com
telephones or your VCX system on Virtual LANs, you can configure
your DHCP server to specify VLAN ID numbers for each scope. You can
also enable and disable VLAN operation for each DHCP scope.
■
Fail-Over Call Route Point — You can define a single fail-over route
point (IP address) and an associated dial string for SIP devices such as
telephones to use.
If a failure occurs on the Primary VCX Call Processing Server, the
telephone switches to the Secondary VCX Call Processing Server. If
both are unavailable, the telephone switches to peer-to-peer SIP
operation and attempts to connect to the IP address of the fail-over
route point. The dial string controls the types of calls that can be made
while the telephone is in peer-to-peer mode.
