Phone Settings - Fortinet FortiFone-450i User Manual

PHONE SETTINGS

The Phone Settings page contains a mix of parameters that should only be changed if familiar with the
resulting change.
Phone Settings
• Frame Duration: Sets the interval to send/receive RTP packets in milliseconds. Do not change this
value if you do not understand the settings.
• Headset Auto Mode: When enabled, the phone will switch to the headset port when calls are placed
from the phone book or call logs.
• DTMF Relay: Configure the method for DTMF signaling (in-band, out-of-band or negotiate). Do not
change this value if you do not understand the settings.
• DTMF Payload: Configure the payload type for DTMF signals according to RFC 2833. Do not change
this value if you do not understand the settings.
• DTMF Duration: Configure the duration of DTMF signals sent from the phone in milliseconds. Do not
change this value if you do not understand the settings.
• The Number of Lines: Sets the number of flexible buttons allocated for lines. The minimum is one
(1). The maximum number of line buttons is the maximum number of buttons available on the phone.
If using buttons for SIP accounts, then set the number of lines to match the number of accounts to be
used or depth per account. For example, selecting 2 lines but configuring the same phone number for
both lines will allow for 2 calls per button to be handled for a total of 4 calls. Do not change this value
if you do not understand the settings.
