Soft key parameter values

Last Updated : Jun 17, 2025 |

This section contains the full list of soft key parameter values and their attributes.

Each soft key has a set of attributes that can be configured for the soft key parameter:

  • Type: key type, a mandatory value, the list of available values depend on the Call Appearance States.

  • Action: value depends on the type and the Call Appearance States selected.

  • Label: soft key label, optional value. The value accepts non-Latin symbols.

    Note:

    If you do not specify the Label value, the default built-in Label is used for the Type=Function, and the Action value is used for all other Type.

Following is the syntax for the soft key parameter: 
SET SOFTKEY_<state> "type=<type>;action=<action>;label=<label>"
To add multiple soft keys use the ADD command.

For the full list of allowed values, refer to the table below. For additional settings of the SOFTKEY parameter, refer to the Additional parameters column.

Redirect

Attr1: allows valid SIP URI characters such as: leading +, asterisk (*), pound (#), at (@), comma (,), minus (-), underscore (_), 0–9, a-z, A-Z. Currently, only one Redirect soft key is supported.

For example:

Attr1=some_address
Attr1=some_address@domain.com
Attr1=+16135555555@domain.com
Attr1=+16135555555
Attr1=16135555555
Attr1=*088063#

If you do not set the value per the defined rules, the Attr1 is undefined. However, the Redirect soft key appears.
