Voice Mail Integration
The phone is compatible with voice mail servers. The subscribe contact and 
callback mode can be configured per user/registration on the phone. Voice 
mail access can be configured to be through a single key press. A 
message-waiting signal from a voice mail server triggers the message-waiting 
indicator to flash and the call waiting audio tone is played through the active 
audio path. 
Configuration changes can be performed centrally at the provisioning server 
or locally. For detailed information on configuration file settings, refer to

Shared Call Appearances
Calls and lines on multiple phones can be logically related to each other. A call 
that is active on one phone will be presented visually to phones that share that 
call appearance. Mutual exclusion features emulate traditional PBX or key 
system privacy for shared calls. Incoming calls can be presented to multiple 
phones simultaneously. Users at the different locations have the ability to 
interrupt remote active calls.
This feature is dependent on support from a SIP server that binds the 
appearances together logically and looks after the necessary state notifications 
and performs an access control function. 
Note
Your SIP server provider should be consulted for recommended methods of 
configuring phones and servers for fail-over configuration. Static DNS cache should 
only be used when you cannot install the correct entries into the DNS server.
The use of the static DNS cache is required when connecting into a Cisco Unified 
Communications Manager system. This is because Cisco Unified Communications 
Manager does not support simultaneous registrations from a single device to 
multiple subscribers in the Cisco Unified Communications Manager cluster. The 
recommended DNS cache configuration would list two subscriber IP addresses, 
then an SRST reference (if one is present). This causes the Polycom VVX 1500 C 
phone to attempt registration to a single subscriber based on the order of the IP 
Addresses listed in the DNS cache. If the first subscriber in the list is down, the 
Polycom VVX 1500 C will try the second subscriber, and then third. If a subscriber 
comes back online, the Polycom VVX 1500 C will attempt to re-register to that 
subscriber.
