Line Keys and Programmable Keys
Programmable keys can also be set up to quickly to access features such as Call Return (*69) or
Voicemail.
The following paragraphs describe how to configure each function listed in the previous table.
Phone Lock Indicates the key is configured as a phone lock key, allowing you to press this
key to lock/unlock the phone.
Paging Indicates the key is configured as a Paging key. When pressed, the phone can
send Real Time Transport Protocol (RTP) streams from a pre-configured
multicast address without involving SIP signaling. You can also receive RTP
streams from pre-configured multicast addresses (can specify up to 5
addresses) using the "Paging Listen Addresses" at the path,
Basic Settings->Preferences->Group Paging RTP Settings in the Aastra Web
UI. For more information about setting this parameter, see
“Group RTP Paging
(receives RTP streams)” on page 184 .
Note: Quick access features like Call Return and Voicemail must first be configured
on your PBX in order to work on your phone. See your System Administrator for
more information.
