Configuring SIP PRA Agent Registration

1

Configure interface addresses and address pools

Enter the system view.

system-view

-

Enter the interface view.

interface interface-type interface-number

-

(Optional) Bind a VPN instance to an interface.

ip binding vpn-instance vpn-instance-name

Before running the ip binding vpn-instance command, create a VPN instance.

When you run the ip binding vpn-instance command on an interface, all Layer 3 features on the interface, such as the IP address and routing protocol, are deleted. To use these features, re-configure them.

By default, no VPN instance is bound to an interface.

Configure an Ethernet IP address.

ip address ip-address { mask | mask-length }

If you configure a new IP address for an interface that already has an IP address, the new IP address overwrites the old one.

Return to the system view.

quit

-

Enter the voice view.

voice

-

Add an IP address to the signaling IP address pool.

voip-address signalling interface interface-type interface-number { ip-address | dynamic }

To specify the ip-address parameter, ensure that an IP address has been configured for the specified interface. To specify the dynamic parameter, ensure that an IP address has been dynamically allocated to the specified interface.

Add an IP address to the media IP address pool.

voip-address media interface interface-type interface-number { ip-address | dynamic }

It is recommended that the media and signaling IP address pools be the same.

(Optional) Configure a bound VPN instance.

voip-vpn-instance vpn-instance-name

Only SIP trunk groups can be bound to VPN instances.

Before running the voip-vpn-instance command, ensure that a VPN instance has been created and interfaces to which the signaling IP addresses and media IP addresses belong have been bound to the instance.

By default, no VPN instance is specified to be used by voice services.

Configure the interface and type for the media relay.

sbc media-relay

-

2

Configure an enterprise and a DN set

Create an enterprise and enter the enterprise view

enterprise enterprise-name

-

Configure the DN set

dn-set dn-set-name [ description description ]

-

3

Configuring the SIP server

Enter the SIP server view.

sipserver

-

Configure the signaling IP address and signaling port number of the SIP server.

signalling-address { ip ip-address | addr-name addr-name-value } port port-value

The signaling IP address of the SIP server must be allocated from the signaling IP address pool on the corresponding interface.

Configure a signaling domain name for the SIP server that uses a dynamic signaling IP address.

signalling-domain signaling-domain-value

If the SIP server uses a dynamic signaling IP address, you must configure a signaling domain name for the SIP server.

Configure the media IP address of the SIP server.

media-ip { ip-address | addr-name addr-name-value }

The media IP address of the SIP server must be allocated from the media IP address pool on the corresponding interface.

Configure the URI for the SIP server.

register-uri uri

The Uniform Resource Identifier (URI) is used for SIP user registration.

Configure the home domain for the SIP server.

home-domain domain

The SIP server fills this parameter into the From field in SIP messages.

Enable media proxy.

sbc media-proxy enable

-

Reset the SIP server.

reset

-

4

Configure a call route

Create a call route

callroute callroute-name

-

Configure a call route policy

selecttype selecttype-value

-

5

Configure a trunk group

Create and enter the SIP PRA trunk group view

trunk-group name sip trunk-group

-

Bind a route mode

callroute callroute-name

-

Configure a local signaling IP address and port number

signalling-address { ip ip-address | addr-name signal-addr-name-value } port port-value

-

Configure a local media IP address or dynamic media IP address name

media-ip { ip-address | addr-name addr-name-value }

-

Configure a peer IP address and port number (select a static or DNS mode based on actual needs)

peer-address static primary-ip-address primary-port-value [ secondary secondary-ip-address secondary-port-value ]

Configure in static mode.

Interconnection data for a trunk group must be consistent with the actual peer data.

peer-address { dns-a primary-domain-value primary-port-value [ secondary secondary-domain-value secondary-port-value ] | dns-srv domain-value | dns-naptr domain-value }

Configure in DNS mode.

Interconnection data for a trunk group must be consistent with the actual peer data.

Configure the home domain name of a peer trunk group

home-domain value

Set this parameter based on peer requirements.

Configure the URI of the registration server

register-uri register-uri-value

Set this parameter based on peer requirements.

Configure an identifier and authentication password for a registration group

register-id register-uri-value [ password cipher password-value ]

To implement SIP PRA group registration, an identifier and authentication password must be configured for a registration group.

You can obtain an identifier and authentication password for a registration group from the service provider (such as IMS network provider).

(Optional) Configure the enterprise and DN set for a trunk group

enterprise enterprise-name [ dn-set dn-set-name ]

Perform this operation only when multiple enterprises and DN sets are configured.

Enable the media agent

sbc media-proxy enable

-

Reset a trunk group

reset

After a SIP trunk group is created or its parameters are modified, reset the SIP trunk group for the settings to take effect.

6

Configure users

Create a SIP user and enter the user view

pbxuser name sipue [ enterprise enterprise-name ]

-

Configure the user device identifier

sipue eid-value

It is recommended that the device identifier and name of a user be the same.

Configure the user telephone number and long number

telno telno-value [ long-telno long-telno-value ]

A long number is allocated by the carrier network. When a user's long number is configured, extranet users can directly dial the long number to reach the user without dialing the switchboard number and then the extension number.

Configure the user authentication password

eid-para password cipher password-value

Configure the authentication password. Perform this operation to prevent unauthorized registration and toll frauds.

7

Configure group registration

Create and enter the group registration view

groupreg groupreg-name

-

Configure an identifier for group registration

impi impi-value impu impu-name [password cipher]

It is recommended that IMPI and IMPU values be consistent with those on the IMS.

Add a SIP user to the registration set

pbxuser user-name [ step step-value ][number number-value ]

If multiple SIP users are available, add all these SIP users to the registration set.

Configure agent registration

bind trunk-group trunk-group-name

-

Configure the domain name in group registration

home-domain home-domain-value

-

8

Configure incoming and outgoing prefixes

Create and enter the prefix template view

callprefix callprefix-name

-

Configure the prefix

prefix prefix

-

Configure the prefix call type and call attribute

call-type category callcategory attribute attribute

-

Configure the number analysis length

digit-length minimum-length-value maximum-length-value

The number analysis length also contains the prefix. For example, if the number analysis length is set to 5 and the prefix is 88, the analyzed number is 88***.

The maximum number analysis length must be greater than or equal to the minimum number analysis length.

(Optional) Bind a route mode

callroute callroute-name

Perform this operation only when you need to configure the outgoing prefix.

(Optional) Configure the enterprise and DN set for the prefix

enterprise enterprise-name [ dn-set dn-set-name ]

Perform this operation only when you need to configure the incoming prefix.
