If the customized codec preference list is configured as “All”, the phone will set the codec order
of preference as per the following table:
You can specify a customized codec preference list on a global-basis using the configuration
files or the Mitel Web UI.
OUT-OF-BAND DTMF AND DTMF METHOD
The IP phones support out-of-band Dual-Tone Multifrequency (DTMF) mode as referenced in
RFC2833. In the Mitel Web UI, you can enable or disable this feature as required. The
"out-of-band DTMF" is enabled by default. In out-of-band mode, the DTMF audio is
automatically clamped (muted) and DTMF digits are not sent in the RTP packets. You can
configure out-of-band DTMF on a global-basis using the configuration files or the Mitel Web UI.
An additional feature on the IP phone allows you to select the DTMF method that the phone
uses to send DTMF digits from the IP phone via INFO messages. You can set the DTMF method
as Real-Time Transport Protocol (RTP), SIP INFO, or both. You can configure the DTMF method
on a global or per-line basis using the configuration files or the Mitel Web UI.
