that use a softswitch’s Shared Call Appearance feature combined with Polycom’s “type=shared”
line configuration. The features are specific to such Polycom phones when an V2IU is operating
in Local survivability mode.

o Provide support for Shared Call Appearances when in Local mode.
o See the Edgewater Knowledgebase for specifics of configuring these functions.

• Add FTP Server support. Provides the ability to deliver phone-configuration files to
phones via FTP.

Fixes and Enhancements

• Provide H.323 support for inbound Location Requests ( LRQs) on the V2IU -E’s WAN when
the V2IU-E is operating in Embedded Gatekeeper mode.

o This feature is intended to provide support for interoperability with the Vcon Gatekeeper.
o Note that this feature does not provide support for outbound calls from LAN-side clients.

Full neighboring support for the V2IU-E’s embedded gatekeeper is not yet provided.

• Add support for use of a SIP port number provided in DNS SRV record lookup.

• H.323 bandwidth fixes:
o Save and display entered maximum total bandwidth. Previously displayed a calculated

value which showed rounding error.
o Correctly show total bandwidth, even a maximum isn’t enforced.
o Apply the system-wide maximum bandwidth cap, if specified.

• Fix bug where Set Link page always displayed a link rate of Autonegotiate, even if
previously configured differently.

• Fix memory leak in H.460 support

• Correction to a prior fix addressing ALG crash when softswitch references RTP connections
no longer known to the ALG

• Fixed a problem caused by survivability logging filling up the / var filesystem. The full
filesystem prevented phones from registering even if the V2IU-E was operating in Remote
mode. Unnecessary logging has been disabled to prevent filling up the filesystem.

• Fixed AUEP flooding problem with MGCP survival ping client.

• Fix bug where PPPoFR link, when configured from factory default state, would not come up.
Start up T1 for PPPoFR even when WAN_IP never set.

• Fix bug in V2IU-S systems firewall preventing VRRP from operating.

1. 7960/7940: Version 6.0/7.3 (or later)

2. 7905/7912: Version 1.3 (or later)

3. ATA-186: Version 3.2.1 (or later)
