5-152 41-001160-00, Rev 01 Release 2.0 Operational IP Phone Features Operational Features Priority Alerting Priority alerting on the IP phones is a feature that allows incoming calls to trigger pre-defined ringing or call waiting alert tones. You can enable or disable priority alerting on the IP phone for the Asterisk, Broadworks, and Sylantro servers using the configuration files and the Aastra Web UI. Configuration of priority alerting is on a global-basis only. How Priority Alerting Works When the IP phone detects an incoming call, the phone firmware inspects the INVITE request in the IP packet for an "Alert-Info" header. If it contains an "Alert-Info" header, the firmware strips out the URL and keyword parameter and maps it to the appropriate Bellcore tone. If there is no keyword parameter in the "Alert-Info" header, or the INVITE message contains no "Alert-Info" header, then the IP phone firmware uses the Bellcore standard ring tone. Asterisk/Broadworks Servers The ring tone keywords that can display in the "Alert-Info" header for an Asterisk and Broadworks server are: Asterisk/Broadworks Sesrver Ring Tone Keywords Bellcore-dr2 Bellcore-dr3 Bellcore-dr4 Bellcore-dr5 When the ring tone keywords appear in an "Alert-Info" header from an Asterisk or Broadworks server, the IP phone maps the keywords to the default ring tone patterns. Operational 41-001160-00, Rev 01 Release 2.0 5-153 IP Phone Administrator Guide Operational Features Operational IP Phone Features Sylantro Servers The ring tone keywords that can display in the "Alert-Info" header for a Sylantro server are: Sylantro SesrverRing Tone Keywords alert-acd (auto call distribution) alert-community-1 alert-community-2 alert-community-3 alert-community-4 alert-emergency alert-external alert-group alert-internal alert-priority When the ring tone keywords appear in an "Alert-Info" header from a Sylantro server, the keyword is mapped to the ring tone pattern based on the configuration you set in the Aastra Web UI or the configuration files. Ring Tone Patterns In IP Telephony, different ringing patterns have different frequencies and cadences. Ring cadence is the ringing pattern heard by the called party, before they pick up the call. On the IP phones, if you enable priority alerting when using an Asterisk or Broadworks server, the IP phone uses the following Bellcore-specified tones by default: Ring Tone Pattern (Asterisk/Broadworks Servers) Call Criteria Bellcore Tones internal calls Bellcore-dr2 external calls Bellcore-dr3 calls with contact list Bellcore-dr4 calls with specific time frames Bellcore-dr5 5-154 41-001160-00, Rev 01 Release 2.0 Operational IP Phone Features Operational Features If you enable priority alerting when using a Sylantro server, you can specify the Bellcore tone to be used for the following configurable criteria: Ring Tone Pattern (Sylantro Servers) Call criteria Bellcore tones for each call criteria alert-acd (auto call distribution) alert-community-1 alert-community-2 alert-community-3 alert-community-4 alert-emergency alert-external alert-group alert-internal alert-priority Normal ringing (default) Bellcore-dr2 Bellcore-dr3 Bellcore-dr4 Bellcore-dr5 Silent Operational 41-001160-00, Rev 01 Release 2.0 5-155 IP Phone Administrator Guide Operational Features The following table identifies the different Bellcore ring tone patterns and cadences.

A discreet tone alerts you to the new caller, so you can answer your second incoming call by putting your first caller on hold. The IP phones use the following Bellcore-specified call waiting tones.
