Notes about parameters on this page:
STUN
: using STUN is recommended for a SIP
link via an access router with NAT. The public
address and type of NAT are detected and
displayed on the
S
TATUS
home page (see
p. 10).
Default Protocol
: the one used for an
outgoing call.
SIP-Registrar
: IP address or domain name. To
specify a port other than the standard 5060,
add “:” and port number, as in the following
example: sip.aeta-audio.com:5070.
SIP Port
,
RTP Port
(SIP) : these are the local
ports of the codec.
Keepalive Interval
(SIP): reduce if necessary
to be lower than the translation time out in
the NAT router.
Send Only
(Direct RTP): if this box is not
checked, the codec is full-duplex, and expects
to receive a stream during a link. If not
receiving data, it releases the link after the
“
RTP Timeout
” period. If the box is checked,
the codec sends data but does not expect any
data in return.
RTP Port
(Direct RTP): must not be same as
the
SIP Port
. This is the local port; the same
number is used for the destination of a call,
unless it is explicitly specified in the call
destination.
