Question: Does the BudgeTone support distinctive ringtone feature using ALERT-INFO Method?
Answer:

Currently, BT phones support Distinctive Ringing for 3 specific Phone Numbers/Extensions/User IDs. You will find this setting on Advanced Settings Page. Basically you can configure 3 extensions with a Ringtone each and then whenever incoming call is from one of these numbers, that configured Ringtone will play. The BT200 model supports Distinctive Ringtones using SIP ALERT-INFO header.

BT200 supports the Alert-Info mapping to the 3 custom ring tone files. For example, if you configure the custom ring tone 1 user id to “priority” (instead of a real user ID), that ring tone will be used if we receive INVITE with Alert-Info header in the following format:

Alert-Info:;info=priority
