Datasheet

Specific manager page—Allows the administrator to view specific information for that manager

Continued support for important Cisco Unified CallManager Assistant features such as handling calls, Immediate Divert,

Transfer to Voicemail, Filter Calls, Do not Disturb, etc.

●

Complete transfer by going on hook—This feature was first introduced in Cisco Unified CallManager 4.1(3). If the “Transfer On-

Hook Enabled” service parameter is enabled, a user can complete a transfer by going on hook. Feature invocation is as follows:

Hit the transfer soft key.

Dial the number to transfer the call to.

Go on hook.

SYSTEM CAPABILITY ENHANCEMENTS

●

Automatic-alternate-routing (AAR) support for forwarding calls on no bandwidth—New fields have been added to AAR that

allow a system administrator to redirect calls to an alternate destination (or the original phone through the PSTN if SRST is

installed) on a no-bandwidth condition. The new parameters also allow the call to be forwarded directly to centralized voicemail if

desired.

●

Call forward on nonregistered—New forwarding conditionals have been added to the line administration page that give the

system administrator the ability to forward calls to a destination that is different from the Call Forward No Answer destination. This

setup allows Cisco Unified CallManager to route calls destined for phones at remote sites even when the WAN is down between the

remote and central sites.

●

Device mobility—The system administrator can provide a mapping of IP subnets to device pool and location information. When a

phone registers with Cisco Unified CallManager and has moved out of its home location, the Cisco Unified CallManager updates

the device pool and location information to correctly reflect the location that the phone has moved to.

●

H.323 Overlap Sending and Receiving—Cisco Unified CallManager 4.2 now supports overlap sending and receiving for H.323

gateways and intercluster trunks. MGCP overlap sending that was supported in previous versions will continue to be supported.

●

H.323 Annex M.1 support for H.323 gateways and H.225 trunks—First introduced in Cisco Unified CallManager 4.1(3), this

feature supports H.323 Annex M.1 for H.323 gateways and, in the future, for connection to other vendors’ private branch exchange

(PBX) through an H.225 trunk. At the release of Cisco Unified CallManager 4.2, no certification testing had been completed for

interoperability with other PBX equipment.

●

MLPP enhancements—The following MLPP enhancements have been made:

Interworking and tunneling of PRI 4ESS UUIE-based MLPP over an ICT—Allows MLPP information to be passed across an

intercluster trunk

DSCP-to-MLPP precedence-level mapping—Allows Cisco Unified CallManager to set the Type of Service (TOS) field in the

IP header with the higher DSCP value based on the MLPP precedence level, determining the DSCP value to be used in the RTP

media stream

●

V.150 secure modem support over an intercluster trunk—Although V.150 modem relay support was introduced in Cisco

Unified CallManager 4.1, calls over an intercluster trunk could not support V.150. Cisco Unified CallManager 4.2 now supports

V.150 calls across an intercluster trunk.
