Introduction

Distinctive Ring offers the possibility to use different ringtones for Internal, external or group calls.

Distinctive ringing is implemented in:

• DE700/900 Release 02.00.05 or higher
• DE310/410 Release 02.00.02 or higher
• N510 Software 236 or higher (Support for Alert-info Internal ringtone, all others are played as external ringtones.)
• N720 Software 99 or higher (Support for Alert-info Internal ringtone, all others are played as external ringtones.)
• Maxwell 10
• Maxwell 3 and Basic

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)

Example header send to N510 behind Gigaset T440/T640
