Some supported features shown in Table 2 can be invoked by dialing a Feature Name Extension

(FNE). Or, a speed dial button on the telephone can be programmed to an FNE. Communication

Manager automatically handles many other standard features such as call coverage, trunk

selection using Automatic Alternate Routing (AAR) and Automatic Route Selection (ARS),

Class Of Service/Class Of Restriction (COS/COR), and voice messaging. Details on operation

and administration for Communication Manager can be found in References [4-6].

4.2. Operational Notes

4.2.1. Do Not Disturb

When Do Not Disturb is activated, the call is not presented to or displayed on the phone. The

call follows the coverage path configured for the extension in Communication Manager. This

feature is locally supported by the telephone, and is recommended instead of the Communication

Manager FNEs for Send All Calls and Send All Calls Cancel.

4.2.2. Call Forward Unconditional

It is recommended that this feature be administered as a Communication Manager FNE rather

than using the local call forward of the telephone. The user of local call forward will not benefit

from any of the call coverage features available in Communication Manager, including coverage

to voice messaging.

4.2.3. Calling Name/Number Block

The Avaya 1100- and 1200-Series IP Deskphones support privacy by means of the Remote-

Party-ID SIP header in the INVITE message. Since Communication Manager supports the

newer Privacy header along with P-Asserted-Identity header, this local feature is not supported.

It is recommended that the Calling Number Block FNE in Communication Manager be used

instead. This can be configured as speed dial button on the telephone (see Sections 5.8 and 7.4).

4.2.4. Priority Call

The telephone may originate priority calls based on the class of service administered for it (see

Section 5.9) or if the user dials the appropriate FNE. Note however, that it will not indicate a

received priority call. Avaya 9600 Series IP Telephones (SIP, H.323) and Avaya 6408D+

Digital Telephones will properly indicate them via distinctive ringing and calling party display.
