Ringtones are not part of the PBX software. Only the ringtones available in the telephones are used.
Call type and number-dependent ringtones
To telephones that support this, the PBX sends information on the call type in the alert info in SIP Invite. The ringtones available in the phone then can be assigned to the different call types using the alert info. This allows, for example, different call types such as internal, external, group and door calls to be distinguished by different ring tones.
In addition, the PBX also transmits the calling or called number depending on the call type. On telephones that can process the transmitted information (COMfortel D-series telephones, firmware version 2.6B or later), it is thus possible to distinguish not only the call types but also the calling and called numbers on the basis of the ringtones.
The following data is transmitted by the PBX in the alert info:
•alert-internal-[calling user number] for internal calls
•alert-group-[called group number] for internal group calls
•alert-external-[called external number] for external calls
•alert-door-[calling door number + door bell button] for door calls
Examples:
•alert-internal-222 for internal calls from the user number 222
•alert-group-123 for internal calls to the group number 123
•alert-external-911977 for calls to the external telephone number 911977
•alert-door-511 for calls from the door 51, door bell button 1
You will find more information about the assignment of ringtones in the telephone in the instruction of the telephone.
Important: The transmission of the calling and called numbers is only available with feature level 3 or higher. If you want to use this function, please contact your dealer or system partner.
