The Platform / provider has to send the correct information using the Alert-Info: Header.
Distinctive Ringing protocol
PBX sends URI of a ring melody in SIP ‘Alert-Info’ header field in the following format:
Alert-Info: <URI>[;<RINGER_INFO>[;<POSTFIX>]]
[] – includes optional parameters
<URI>
URI of the ringer melody. If a special (configurable) URI is used, e.g.: <http://www.example.com>, or <http://127.0.0.1>
then it means for the phone that Alert-Info contains local ring melody tag, otherwise URI points at a ringer melody (in .wav format) in the network, which shall be downloaded and played by the phone.
<RINGER_INFO>
Tag of internal ringer melody in the form <info=TAG>. TAG is configured via phone’s Web UI.
<POSTFIX>
Groupcall:
Alert-Info: <http://www.example.com>;info=alert-group
Internal call:
Alert-Info: <http://www.example.com>;info=alert-internal
In the N510 and N720, there is a new provisioning parameter that provides a limited functionality to change the Alert-Header:
BS_VOIP_Data.aucS_SIPAlertInfoHeaderInternal[0]="alert-internal"
External call:
Alert-Info: <http://www.example.com>;info=alert-external
N510 / N720 how to select the Internal / External ringtone.
Ringtones can only be changed in the DECT handset, there is no web-interface to change the ringtones.
On the handset go to: Menu - Settings - Audio Settings - Ringtones (Handset) - Melodies
- Internal Calls: (The ringtone when the Internal Alert Header is received and recognized)
- Tones for the different SIP accounts. (Ringtone used when it is not an Internal Ringtone)
