Multi Line

SIP Environment

Voicemail number

Specifies the number to reach the voicemail feature of Asterisk. This complies with the exten- sion specified for the feature VoiceMailMain() in the file extensions.conf.

5 Multi Line

During setup, a phone number - or alternatively: a name - is assigned to the telephone; this number or name can be used to call this telephone and is used at the called party’s side to iden- tify the caller.

Very often this is referred to as a (telephone) "line" the telephone is assigned to - in analogy to conventional (TDM) telephones using phone numbers.

In addition, powerful telephones support the so-called "Multi Line" feature. This feature enables one end device to have access to several lines. Apart from that, one line can be assigned to several end devices. If a call comes in on such a shared line, this triggers a ringing tone on all end devices assigned to that line. Depending on the model, optiPoint 410 S / 420 S can attend to up to 10 lines.

If you want to use the Multi Line feature with Asterisk, the parameter pedantic=yes has to be set in the file sip.conf; this ensures that Asterisk can identify the Multi Line Header in the SIP messages (presetting is no).

The lines are not configured in the SIP environment section but using the key programming of the optiPoint telephone. For each line one function key has to be configured as "line" key. User data such as E.164 number, user name and password have to be entered. The LED belonging to the line key indicates the status of that line. For more information about functionality and set- up, please refer to the User Guide and the Administrator Guide (see Section 9, "Reference List").

For each line on the end device there has to be a corresponding entry in the file sip.conf. The server settings have to be entered in the section SIP environment.
