PARAMETER –
sip rtp port
CONFIGURATION FILES
startup.cfg, <model>.cfg, <mac>.cfg
DESCRIPTION
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 parameter 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

PARAMETER –
rtp symmetric port
CONFIGURATION FILES
startup.cfg, <model>.cfg, <mac>.cfg
DESCRIPTION
By default the phones support symmetrical RTP port handling (i.e.
the phone will only play an RTP stream if it comes from a "source"
port that is the same as the "listening" port negotiated by the call
manager.
By disabling this parameter, administrators can configure the phones
to support asymmetrical RTP port handling. If disabled, the phone
will accept an RTP stream coming from a different "source" port and
send RTP traffic to the caller at the "listening" port.
