Setting Up the Polycom VVX 1500 C Phone
Note | Your SIP server provider should be consulted for recommended methods of |
| configuring phones and servers for |
| 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 |
| subscriber. |

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.
