This is the base port from which
the phone transmits and
receives media.
The valid range is an even
number from 3000 to 65408.
65408 is the highest even 16-bit
number that allows enough
headroom for the 64 RTP and
64 RTCP ports that are
reserved when you establish an
RTP base value.
Given an RTP base, the phone
should use the next 64
consecutive even numbers for
RTP ports. If within that range
an existing (reserved) odd or
even UDP port number is used,
the phone should skip over an
even/odd pair to the next even
number.
For example, if the user set
rtpBase to 5550, then 5550,
5552, 5556, 5558, etc., is used
In this example, 5554 is skipped
because 5555 is a reserved
port used by the phonectl
server (actually, 5554 is also
used and also provides a
reason for skipping over 5554).
If an odd number is specified,
the phone should use the next
lowest even number if it fits the
above limitations.
