8.5.3.4 RTP Start port
The phone uses consecutively numbered RTP and RTCP port numbers (actually UDP port
numbers) for communication. RTP carries media and RTCP carries control information.
The default RTP start port is 1760. The first call appearance uses port 1760 to receive media and
port 1761 to receive RTCP control information. The second call appearance uses ports 1762 and
1763. The RTP start port must always be an even number and should not be set to the same value
as the
Receive Port or the Proxy Port.
To access this panel, select Menu | Pswd Settings | SIP Settings | RTP Start Port .
