Chapter 3 Managing Cisco SIP IP Phones
Modifying the Phone’s SIP Settings
nat_received_processing
Optional
Use 0 to disable NAT received processing and 1 to enable
NAT received processing. Default is 0.
If nat_received_processing is enabled, and received= tag
is in the Via header of the 200 OK response from a
REGISTER, the IP address in the received= tag is used
instead of the nat_address in the Contact header. If this
switch occurs, the phone unregisters the old IP address
and reregisters with the new IP address.
network_media_type
Optional
Ethernet port negotiation mode. Valid values are:
•
Auto—Port is autonegotiated.
•
Full100—Port is configured to be a full-duplex,
100-MB connection.
•
Half100—Port is configured to be a half-duplex,
100-MB connection.
•
Full10—Port is configured to be a full-duplex,
10-MB connection.
•
Half10—Port is configured to be a half-duplex,
10-MB connection.
The default is Auto.
network_port2_type
Optional
The device type that is connected to port 2 of the phone.
Valid values are:
•
Hub/Switch (default)
•
PC
Note
If the value is PC, port 2 can be connected only
to a PC. If you are not sure about the connection,
use the default value. Using a value of “PC” and
connecting port 2 to a switch results in spanning
tree loops and network confusion.
outbound_proxy
Optional
The IP address of the outbound proxy server. You can use
either a dotted IP address or a DNS name.
