Could be used for a pool of directly connected CLANs if needed for IP phone registration. 203 - 248 Miscellaneous/Virtual Used for IP phones, CMAPI, Soft phones and other IP endpoints that need an IP Network Region different from its media gateway 249 <reset IP network-region x> Use NR 249 for systems at ACM 3.0 or earlier.

- 46. IPSI Bandwidth Provisioning A general rule of thumb for IPSI Control traffic bandwidth allocation is to add an additional 64Kbps of signaling bandwidth to the minimum required bandwidth in order to manage peak (burst) traffic loads and either round up or down to nearest DS0. For example; for 5K busy hour calls using encrypted PPP links to control remote port networks, as described in the previous example, you would guarantee 128Kbps (69.3Kbps + 64Kbps) for IPSI signaling bandwidth across the WAN link.

- 57. Conference Rates ● Audio pool The audio pool contains bandwidth for all audio calls, including the audio-component of multimedia calls. ● Normal video pool The normal video pool contains bandwidth for the video portion of a call made by a normal (non-priority) video user. You can set this pool to be shared. When this pool is shared, audio-only calls are allowed to borrow bandwidth from this pool. ● Priority video pool The priority video pool contains bandwidth that is dedicated to priority video users only. Audio calls and normal video users are not allowed to borrow bandwidth from this pool. However, if all of the priority video pool bandwidth is currently in use, priority video users can borrow bandwidth from the normal video pool, if available.

Editor's Notes
- The recommended configurations for IP sets is that they use a separate VLAN for voice traffic. This segments broadcasts/multicasts and allows for a certain level of security through ACL’s. The telephone uses a single cable to the Ethernet switch and takes advantage of 802.1q to send data traffic on the native VLAN and voice traffic tagged.
- Linear
- Monitoring performance of endpoints, data network and applications Performance monitoring quality of voice calls, i.e. latency, jitter, and delay Identification of cause of low voice quality Identification and notification about applications on the network that are causing degradation of voice quality Automatic correlation of voice and data alarms to quickly identify root cause and quickly remediate the problem Security monitoring of alarms on IPT Media Servers Fault management and performance reports available via Web Portal Software release management to ensure IPT platforms keep at current updates
