The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Before you install a phone, you must decide how to configure the phone in your network. Then you can install the phone and verify its functionality.
For the phone to successfully operate as an endpoint in your network, your network must meet specific requirements.
Note | The phone displays the date and time from Cisco Unified Communications Manager. The time displayed on the phone can differ from the Cisco Unified Communications Manager time by up to 10 seconds. |
The Cisco IP Phone requires Cisco Unified Communications Manager to handle call processing. See the documentation for your particular Cisco Unified Communications Manager release or the context-sensitive help in the Cisco Unified Communications Manager Administration to ensure that Cisco Unified Communications Manager is set up properly to manage the phone and to properly route and process calls.
Before you install the Cisco IP Phone, you must choose a method for adding phones to the Cisco Unified Communications Manager database.
By enabling autoregistration before you install the phones, you can:
Add phones without first gathering MAC addresses from the phones.
Automatically add a Cisco IP Phone to the Cisco Unified Communications Manager database when you physically connect the phone to your IP telephony network. During autoregistration, Cisco Unified Communications Manager assigns the next available sequential directory number to the phone.
Quickly enter phones into the Cisco Unified Communications Manager database and modify any settings, such as the directory numbers, from Cisco Unified Communications Manager.
Move autoregistered phones to new locations and assign them to different device pools without affecting their directory numbers.
Autoregistration is disabled by default. In some cases, you might not want to use autoregistration; for example, if you want to assign a specific directory number to the phone, or if you want to use a secure connection with Cisco Unified Communications Manager. For information about enabling autoregistration, see the documentation for your particular Cisco Unified Communications Manager release. When you configure the cluster for mixed mode through the Cisco CTL client, autoregistration is automatically disabled. When you configure the cluster for nonsecure mode through the Cisco CTL client, autoregistration is not enabled automatically.
You can add phones with autoregistration and TAPS, the Tool for AutoRegistered Phones Support, without first gathering MAC addresses from phones.
TAPS works with the Bulk Administration Tool (BAT) to update a batch of phones that were already added to the Cisco Unified Communications Manager database with dummy MAC addresses. Use TAPS to update MAC addresses and to download predefined configurations for phones.
Cisco recommends that you use autoregistration and TAPS to add fewer than 100 phones to your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT).
To implement TAPS, you or the end user dials a TAPS directory number and follows voice prompts. After the process is complete, the phone contains the directory number and other settings, and the phone is updated in Cisco Unified Communications Manager Administration with the correct MAC address.
Verify that autoregistration is enabled and is properly configured in Cisco Unified Communications Manager Administration before you connect any Cisco IP Phone to the network. For information about enabling and configuring autoregistration, see the documentation for your particular Cisco Unified Communications Manager release.
Autoregistration must be enabled in Cisco Unified Communications Manager Administration for TAPS to function.
The following steps provide an overview and checklist of installation tasks for the Cisco Unified SIP Phone 3905. The list presents a suggested order to guide you through the phone installation. Some tasks are optional, depending on your system and user needs. For detailed procedures and information, refer to the sources in the list.
Step 1 | Choose the
power source for the phone:
Determines how the phone receives power. For more information, see Phone Power Requirements. | ||
Step 2 | Connect the handset to the Handset port. | ||
Step 3 | (Optional) Connect the power supply to the Cisco DC Adapter port. See Phone Addition Methods for guidelines. | ||
Step 4 | Connect a
straight-through Ethernet cable from the switch to the network port labeled
Network on the
Cisco Unified SIP Phone 3905. Each phone ships with one
Ethernet cable in the box.
You can use either Category 3, 5, or 5e cabling for 10-Mbps connections, but you must use Category 5 or 5e for 100 Mbps connections. | ||
Step 5 | Connect a straight-through Ethernet cable from another network
device, such as a desktop computer, to the access port labeled Computer. You
can connect another network device later if you do not connect one now.
You can use either Category 3, 5, or 5e cabling for 10-Mbps connections, but you must use Category 5 or 5e for 100 Mbps connections. | ||
Step 6 | Monitor the
phone startup process. This step associates directory numbers to the phone and
verifies that phone is configured properly.
For more information, see Verify Phone Startup. | ||
Step 7 | If you are
configuring the network settings on the phone, you can set up an IP address for
the phone by either using DHCP or manually entering an IP address.
For more information, see Configure Network Settings. | ||
Step 8 | Set up
security on the phone. This step provides protection against data tampering
threats and identity theft of phones.
For more information, see Cisco Unified SIP Phone Security. | ||
Step 9 | Upgrade the phone to the current firmware image. | ||
Step 10 | Make calls
with the phone. This step verifies that the phone and features work correctly.
For more information, see the Cisco Unified SIP Phone 3905 User Guide for Cisco Unified Communications Manager. | ||
Step 11 | Provide
information to end users about how to use their phones and how to configure
their phone options. This step ensures that users have adequate information to
successfully use their phones.
For more information, see Cisco IP Phone User Support. |
The phone includes many configurable network settings that you may need to modify before the phone is functional for your users. You can access these settings, and change some of them, through menus on the phone.
The phone includes the following setup menus:
Network Setup: Provides options for viewing and configuring a variety of network settings.
Security Setup: Provides options for viewing and configuring a variety of security settings.
Before you can change option settings on the Network Setup menu, you must unlock options for editing.
You configure settings that are display-only on the phone in Cisco Unified Communications Manager Administration.
To display a configuration menu, follow these steps:
Step 1 | Press Applications . | ||
Step 2 | Select Admin Settings. | ||
Step 3 | Select
Network or
Security.
| ||
Step 4 | Enter your user ID and password, if required, then press Select. | ||
Step 5 | Perform one of these actions to display the desired menu: | ||
Step 6 | To display a submenu, repeat step 5. | ||
Step 7 | To exit a menu, press Back. |
You can apply a password to the phone so that no changes can be made to the administrative options on the phone without password entry on the Administrator Settings phone screen.
When you edit the value of an option setting, follow these guidelines:
To delete a character to the left of the cursor, use the Hold/Resume button.
Note | The Cisco IP Phone provides several methods to reset or restore option settings, if necessary. |
If you are not using DHCP in your network, you must configure these network settings on the phone after installing the phone on the network:

After the Cisco IP Phone has power connected to it, the phone automatically cycles through a startup diagnostic process.
Step 1 | If you are using Power over Ethernet, plug the LAN cable into the Network port. |
Step 2 | If you are using the power cube, connect the cube to the phone and plug the cube into an electrical outlet. The buttons flash amber and then green in sequence during the various stages of bootup as the phone checks the hardware. If the phone completes these stages successfully, it has started up properly. |
