Soft key parameter values

Last Updated : Apr 17, 2026 |
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.

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_addressAttr1=some_address@domain.comAttr1=+16135555555@domain.comAttr1=+16135555555Attr1=16135555555Attr1=*088063#
If you do not set the value per the defined rules, the Attr1 is undefined. However, the Redirect soft key appears.
