Indicates the port through which the RTP packets are sent. This value must specify the
beginning of the RTP port range on the gateway or router.
The RTP port is used for sending DTMF tones and for the audio stream. Your network
administrator may close some ports for security reasons. You may want to use this param-
eter to send RTP data using a different port.
Note:
The phones support decoding and playing out DTMF tones sent in SIP INFO requests. The
following DTMF tones are supported:
• Support signals 0-9, #, *
• Support durations up to 5 seconds
