Modifying the Phone’s SIP Settings
Step 4
When done, press the Save soft key. The phone programs the new information into Flash memory and
resets.
Caution
When you have completed your changes, ensure that you lock the phone as described in the
“Locking
Configuration Mode” section on page 3-2
.
Modifying the Phone’s SIP Settings
You can modify the SIP parameters of a Cisco SIP IP phone.
When modifying SIP parameters, remember the following:
•
Parameters defined in the default configuration file override the values stored in Flash memory.
•
Parameters defined in the phone-specific configuration file override the values specified in the
default configuration file.
Network Media Type
Yes
Ethernet port negotiation mode. Valid values are:
•
Auto—Port is autonegotiated. (This is the default value.)
•
Full-100—Port is configured to be a full-duplex, 100-MB
connection.
•
Half-100—Port is configured to be a half-duplex, 100-MB
connection.
•
Full-10—Port is configured to be a full-duplex, 10-MB
connection.
•
Half-10—Port is configured to be a half-duplex, 10-MB
connection.
Network Port 2 Device Type
Yes
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.
Operational VLAN Id
No
Unique identifier of the VLAN of which the phone is a member.
This identifier is obtained through Cisco Discovery Protocol (CDP).
Subnet Mask
Yes, but DHCP must
be disabled.
IP subnet mask used by the phone. A subnet mask partitions the
IP address into a network and a host identifier.
TFTP Server
Yes, but DHCP must
be disabled.
IP address of the TFTP server from which the phone downloads its
configuration files and firmware images.
