The Cisco Unified IP Phone includes configurable network settings that you may need to modify before the phone can be used. You can access, view, and change the network settings on the phone by accessing the Interactive Voice Response (IVR) tool. Other configuration settings may be configured in Cisco Unified Communications Manager.
Before the Cisco Unified IP Phone can function, you must configure the network setting on the phone. You can review the configuration of a phone by accessing IVR on the phone. When the phone is connected to a network with a DHCP server, you can use the DHCP server to configure the network settings. You can also manually configure the phone by accessing the IVR.
The following table describes the options that
can be configured on the IVR.
Table 1 Phone Setting Options
Indicates whether the phone has DHCP enabled or disabled.
When DHCP is enabled, the DHCP server assigns to the phone an IP
address, subnet mask, default router, and TFTP Server. When DHCP is disabled,
the administrator must manually assign the IP address, subnet mask, default
router, and TFTP server on the phone.
Internet Protocol version 4 (IPv4) address of the phone.
If you assign an IP address with this option, you must also
assign a subnet mask and default router. See the Subnet Mask and Default Router
options in this table.
Subnet mask used by the phone.
Default Router 1
Default router used by the phone (Default Router 1).
Primary Trivial File Transfer Protocol (TFTP) server used by
the phone. If you are not using DHCP in your network or you want to change this
server, you must assign the TFTP Server.
Indicates whether the phone has 802.1x security enabled or
Dynamic Host Configuration Protocol (DHCP) automatically
assigns IPv6 addresses to phones when you connect them to the network. Cisco
Unified IP Phones enable DHCP by default.
IPv6 Default Router 1
Default IPv6 router used by the phone (Default Router 1).
IPv6 address of the phone. The IPv6 address is a 128 bit
IPv6 Prefix Length
Subnet prefix length used by the phone. The subnet
prefix length is a decimal value from 1 to 128 that specifies the portion of the
IPv6 address that comprises the subnet.
IPv6 TFTP Server
Indicates whether the phone uses the IPv6 Trivial File
Transfer Protocol (TFTP) server.
Access Phone Configuration Settings
You can change the PIN of the IVR from the Common Phone
When there is no User ID or PIN associated with a phone, the phone
uses a default PIN of 24726.
Access the Cisco Unified Communications Manager administration.
Device > Device
Settings > Common Phone Profile.
Specify a PIN for the Local Phone Unlock PIN
field in the Common Phone Profile Configuration window.
To access the IVR and configure the phone settings, follow
these steps on the phone:
You can change the PIN by using the
Local Phone Unlock Password in the Common Phone Profile
Configuration page of the Cisco Unified CM Administration web page.
Go off-hook and press
star (*), pound (#), and
0 keys simultaneously. On the Cisco Unified
IP Phone 6911, you can also access IVR by pressing the speaker button followed by the *, #, and
0 keys simultaneously.
The IVR prompts for a password.
Cisco Unified IP Phone 6901 and 6911 supports alphanumeric characters (A-F), and
colon (:) in IPv6 settings.
