SIP Proxy
The parameters on this page will identify the server that will be used for a call setup to and from
the DCC_VoIP phone. Your ISP or network administrator will provide the necessary information
to be used here.
If
SIP registration
is required with the server then set this switch to Y
es
. If the phone is
configured to dial a direct IP location then this switch can be set to
No
.
Type the Server address and the port (
usually 5060 for SIP
) into the next 2 input boxes. The
SIP
Domain
is the address where an outgoing call information is sent to, and if the domain is via the
internet then it will require the
Outbound Proxy
to be set to
Yes
.
The user ID’s, and PIN are supplied by the ISP/Network administrator, this information is case
sensitive and should be typed in correctly. The
User Name
is relayed to the connecting IP
telephone as a caller ID and is optional.
Local SIP
and
RTP
port numbers are sent to the router/firewall and are use to provide paths for
voice and control data to and from the phone.
The
Register Expiration
and the
Keep Alive
timers keep the SIP server mapping and NAT
ports open, these interval are generally set to 60 and 20 seconds respectively.
If a
Provisional Response Acknowledge PRACK
is required within your network, then enable the
Support PRACK(100rel,RFC3262)
option.
The SIP
Proxy Required
field may need to be set for Nortel MCS servers, if so, set this field to
“
com.nortelnetworks.firewall
”
If the network server is behind a NAT, then enable the
NAT Traversal
and set either the
NAT IP
or
STUN server
address and port.
