Redundancy

Redundancy

This section describes how to configure redundancy for the IP phone.

Context

SIP server redundancy

A maximum of five SIP server addresses can be configured for an HUAWEI IP Phone 7920/7960, and so can the proxy server addresses. The five servers have similar functions but different priorities. When SIP servers 1-4 are faulty, the IP phone connects to SIP server 5 to ensure functional services.

The rule for registration retry on a server is as follows: An IP phone retries registration to a SIP server at an interval of T1, 2 x T1, 4 x T1, 8 x T1, and so on. When the interval is equal to or greater than T2, the IP phone retries registration at intervals of T2 until the total retry time reaches 8 x T2. T1 and T2 are SIP signaling parameters. The default value of T1 is 500 ms and that of T2 is 4000 ms.

Rule for sequential registration: An IP phone sends a registration request to SIP server 1 and if this server fails to respond, the IP phone retries its registration following the rule for registration retry on a server within 3s. If the registration still fails 3s later, the IP phone stops its retry and sends a registration request to SIP server 2. The subsequent process is the same as the preceding description, which is sending a registration request to the next server upon 3s retry failures. The 3s interval is not configurable.

uPortal redundancy

  • For an office with the DNS server

    The common domain name of the uPortal server can be resolved into two sub-domain names using SRV, corresponding to two sites. The sub-domain name corresponding to the home site has a higher priority. Each sub-domain name can match at most six IP addresses. The IP phones select two random IP addresses corresponding to the home site for login attempts.

    If the login is successful, the uPortal server returns the site information of the IP phone users' home area, and the IP phones use this site as the primary site and use the other site as the secondary site.

    If the login fails, the IP phones switch to two random IP addresses corresponding to the secondary site for login attempts.

    If the login is successful, the IP phone detects whether the primary site recovers every 30 minutes. Once detecting that primary site recovers, the IP phones triggers authentication on the primary site again.

    Later, users preferentially use the home area's sites for connection and authentication; when the uPortal connection is updated at intervals, the local site is used preferentially for connection attempts.

    NOTE:
    • In the EC6.X networking environment, the server whitelist verification is supported. Only numbers registered at the primary and secondary sites of the uPortal can make calls.
    • If the uPortal authentication fails and only the SIP server address is configured, the emergency login scenario can only ensure that the numbers can make outgoing calls and receive incoming calls from others registered with the same SIP server.

  • For an office without the DNS server

    Enter multiple uPortal IP addresses for redundancy.

ACS server redundancy (TR069 redundancy)

The domain name of the ACS server supports DNS SRV and A record resolution.

  • DNS SRV resolution

    The domain name of the ACS server is resolved using the SRV to obtain the IP addresses of the active and standby eSight servers. IP phones preferentially connect to the active eSight server. When the active eSight server is faulty, IP phones automatically connect to the standby eSight server. After the active eSight server recovers, IP phones automatically switch back to the active eSight server.

  • A record resolution

    The domain name of the ACS server can be resolved using the A record to obtain several IP addresses (with no priorities distinguished). If three or more IP addresses are returned, IP phones use two IP addresses for access.

    NOTE:

    When eSight is used to deliver deployment tasks, the IP phone can obtain the IP address by resolving the domain name of the file server through the DNS. In this way, the DR function is implemented.

Call redundancy

HUAWEI IP Phone 7920/7960 supports redundancy of the call service.

When the IP phone initiates a call but the current server does not respond, a call failure message is displayed and re-registration is triggered. Call redundancy uses sequential registration. When the IP phone switches to another server for registration and successfully registers with this server, the user only needs to press the call button and then the IP phone initiates the call from the currently registered server.

NOTE:

In the preceding redundancy scenarios, if the domain name solution is used, DNS domain name resolution must be configured. For details about how to configure DNS domain name resolution in different scenarios, see Special Topics > Disaster Recovery (DR) > Configuring the DNS in the CloudEC Product Documentation.

Configuration Methods

You can configure the redundancy function using three different methods, as listed in Table 5-32.

How to Modify the Configuration File

Disaster Recovery

  • Sequential: The IP phone sends registration messages to a SIP server at intervals of half of the registration interval. If the active SIP server fails, the IP phone registers with the standby SIP server. If the standby SIP server also fails, the IP phone registers with the local SIP server. Services are interrupted during the SIP server switching. After the IP phone registers with a SIP server successfully, its services become available again.
  • Simultaneous: The IP phone registers with the active, standby, and local SIP servers at the same time. If the active SIP server fails, the standby SIP server takes over the services. If the standby SIP server also fails, the local SIP server takes over the services. The switching takes about 3s, which is insensible to users. After the switching, services are running properly.

Default: In a UC2.X, or IMS network environment, the default value is Sequential.

Parameter: DisasterRecoveryMode

Location: Device > ComCfg > Phone > Environment

Value range: 0 or 1

  • 0: Sequential
  • 1: Simultaneous

Example: DisasterRecoveryMode="1"

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.
  • In a UC2.X network environment, the SIP server is a gateway of the eSpace U1900 series or EGW1500 series.
  • In an IMS network environment, 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.

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.
