• AudioCodec <n><codec id><description> — is a command that specifies the codecs
that are available for the user to select. You can configure up to 15 codecs.
- n - means the codec number. The value is 1 to 15.
- codec ID - means the codec identifiers are as follows:
• PCMA
• PCMU
• G729
• G723
- text description - a text description of the codec. For more information about audio
codec configuration, see Audio codecs on page 187
• DEF_AUDIO_QUALITY [Low | Medium | High — is a command used to configure the
default audio quality used for each new call. Audio quality can be changed when the call
is active. If this command is not present in the configuration file, the IP Deskphone uses
High quality as its default value. The possible parameters for this command are High,
Medium, and Low. If any other parameter is entered or these commands are misspelled,
the IP Deskphone uses High as the default setting.
The following codecs are used for each selection:
- Low - G729 ptime 30.
- Medium - G711 ptime 30.
- High - G711 ptime 20.
• AUTH_METHOD [AUTH | AUTH_INT] — is used to configure the SIP authentication
method.
- AUTH - only authenticates (username/password)
- AUTH_INT - authentication plus integrity checking (an MD5 hash of the entity is also
computed and checked).
• BANNER [banner_text] — preconfigures the banner on the IP Deskphone. Use a text
string to configure the banner. For example, BANNER ABC Company configures the
banner to ABC Company. The text string can have a maximum of 24 characters.
- banner_text - an ASCII string displayed on the screen of the IP Deskphone with SIP
Software.
• FORCE_BANNER [YES | NO] — is configured by the system administrator through the
configuration file. If FORCE_BANNER is configured as YES, the banner from the
configuration file is reloaded each time the IP Deskphone powers up, even if the user
changes the banner manually.
- YES - causes the banner configured by the administrator to override any banner
configured by the user.
- NO - allows the user to configure the banner.
