Sylantro Servers
The ring tone keywords that can display in the "Alert-Info" header for a Sylantro server are:
• 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 fol-
lowing Bellcore-specified tones by default:
