Table 5-4 Parameter description

Parameter

Description

How to Set

How to Modify the Configuration File

Account Setting

NOTE:

If the SIP server address, SIP server port number, proxy server address, and proxy server port number are specified, the account uses these addresses, free of restrictions by phone settings.

Account

Indicates the ID used for an account to register with the SIP server. The SIP server uses this ID to identify the account. When you dial a long number (country code+area code+short number), the short number is displayed on the dialing screen. When you place a call using a short number, the IP phone obtains the country code and area code of this short number from the AA server to route the call and query the directory.

NOTE:

HUAWEI IP Phone 7920 supports a maximum of three accounts, while HUAWEI IP Phone 7960 supports a maximum of six.

Ask the SIP server administrator for an account or directly log in to the SIP server to configure an account as the administrator.

NOTE:

The phone's first account can be edited but cannot be deleted.

Parameter: Account

Location: Device > UserCfg > Account1

NOTE:

Account1 indicates the first account, Account2 indicates the second account, and so on.

Example: Account="47002"

User Name

Indicates the user name, which is provided by the Voice over IP (VoIP) service provider.

In a UC2.X, EC6.X, IMS or third-party network environment, set this parameter based on requirements.

Parameter: UserName

Location: Device > UserCfg > Account1 > Auth

Example: UserName="47002@example.com "

Password

Indicates the password used to register an account with the SIP server.

Ask the SIP server administrator for a password or directly log in to the SIP server to configure a password as the administrator.

Parameter: Passwd

Location: Device > UserCfg > Account1 > Auth

Example: Passwd="123456"

Label Name

Indicates the name of an account displayed on a line button of the IP phone.

NOTE:

After you set the label name, the IP phone automatically synchronizes it to the server. If Displayname is enabled on the server, the label name will be displayed on the incoming call notification screen of the called party's phone if a call is placed using this account.

The value is automatically pushed by the AA server.

Parameter: LabelName

Location: Device > UserCfg > Account1

Example: LabelName="47002"

Registration Status

Indicates the registration status of an account.

No configuration is required.

-

SIP Server

Specifies the phone registration mode and the SIP server address.

NOTE:

Server 1, Server 2, Server 3, Server 4, and Server 5 represent the active SIP server, standby SIP server, standby SIP server 2, standby SIP server 3, and local SIP server respectively.

When the server switches to Server 4 or Server 5, is displayed in the status bar of the phone.

Enter the IP address of the SIP server based on your network environment.

  • In an EC6.X network environment, the SIP server is the USM server. Enter the domain name of the USM server as the server address.
  • In a UC2.X network environment, the SIP server is a gateway of the eSpace U1900 series or EGW1500 series.
  • In an IMS network, this parameter is set by the administrator.
  • In a CC network environment, the SIP server is a gateway of the eSpace U2900 series, a UAP3300, or a Session Border Controller (SBC).
  • In a third-party SIP server network environment, the SIP server is a third-party SIP server.

Parameters: PrimaryRegServerAddress, BackupRegServerAddress, and LocalRegServerAddress

Location: Device > ComCfg > Phone > Server

Setting:

  • PrimaryRegServerAddress: Set this parameter to the address of the active SIP server.
  • BackupRegServerAddress: Set this parameter to the address of the standby SIP server.
  • BackupRegServer2Address: Set this parameter to the address of standby SIP server 2.
  • BackupRegServer3Address: Set this parameter to the address of standby SIP server 3.
  • LocalRegServerAddress: Set this parameter to the address of the local SIP server.

Example: PrimaryRegServerAddress="192.168.1.9"

SIP Server Port

Indicates the port number of the SIP server.

Enter the port number of the SIP server based on your network environment.

  • In an IMS network, this parameter is set by the administrator.
  • In a UC2.X, EC6.X, or CC network environment, use the default value 5060. However, if TLS is used for SIP signaling transmission, set the port number of the SIP server to 5061.
  • In a third-party SIP network environment, set this parameter to the port number of the third-party SIP server in use.

Parameters: PrimaryRegServerPort, BackupRegServerPort, and LocalRegServerPort

Location: Device > ComCfg > Phone > Server

Setting:

  • PrimaryRegServerPort: Set this parameter to the port number of the active SIP server.

  • LocalRegServerPort: Set this parameter to the port number of the local SIP server.

Example: PrimaryRegServerPort="5060"

Proxy Server

Indicates the address of the proxy server.

The IP phone registers with the proxy server with preference. If the proxy server address you have specified is incorrect, the IP phone will continue its attempt to register with this incorrect address and does not register with the SIP server. This will cause a registration failure.

When the server switches to Server 4 or Server 5, is displayed in the status bar of the phone.

In an EC6.X network environment, enter the signaling IP address of the USM.

In an IMS network, this parameter is set by the administrator.

  • CallOutProxyServer3Address: Set this parameter to the address of standby proxy server 3.
  • CallOutLocalServerAddress: Set this parameter to the address of the local proxy server.

Example: CallOutProxyServerAddress="192.168.1.10"

Proxy Server Port

Indicates the port number of the proxy server.

In an IMS network, this parameter is set by the administrator.

TCP: short for Transmission Control Protocol. This SIP transmission mode ensures the accuracy of signaling transmission. It is recommended when the network conditions are good.

TLS: short for Transport Layer Security. This SIP transmission mode ensures the security of signaling transmission.

Set this parameter based on requirements.

  • If SIP Transport is set to Default, the account uses the phone's SIP transmission mode.
  • If SIP Transport is set to UDP, TCP, or TLS, the account uses its own transmission mode, free of restrictions by phone settings.
NOTE:
  • When a phone connects to the Huawei public cloud, connections using SIP-TLS are not supported.
  • When SIP Transport is set to TLS, you need to configure the time server or manually set the time to the current time to prevent IP phone registration failure.
