PBX

This page is used to configure the connection between the DV2000 and a SIP-enabled PBX.

Local Settings

SettingDescription
PortPort number system should listen for SIP communication on. Default is 5060
Transport ProtocolSIP typically communicates via UDP which is the default. If the PBX is configured for TCP only then choose TCP.

PBX Settings

SettingDescription
AddressIP address or DNS name of the PBX.
PortPort number PBX listens on for SIP communication on. Default is 5060
Expiration TimeEnter the time, in seconds, the channel will wait between registrations with the PBX.

SIP endpoints (channels) are required to maintain registration with the PBX in order to have calls routed to them. Adjust this setting to be less than the maximum for your PBX. For example, the older Avaya IP Office system default to 180 seconds, while other PBX systems have an expiration time of 3600 seconds.

The default value is 3600 seconds.
RealmEnter the realm with which your SIP PBX is configured. This is NOT the DNS domain. For example Asterisk realm should be set to asterisk while Avaya IP Office is ipoffice.
DomainOptionally enter a domain which accounts use to login as. This is typically not set and SIP accounts are just the extension number. In some cases the account might be something like 2001@casino.com. In this case you would enter casino.com and choose to register accounts using the domain field.
Register accounts usingLine configuration does not support the ability to enter the full address of each line. Having the setting here rather than on each line also provides quicker numerical configuration of the accounts.
Examples:
PBX address: 2001@192.168.11.67
Local IP adresss: 2001@192.168.11.100
Domain: 2001@casino.com

Security

TLS Key FilePath to the TLS key file to use. Leave blank unless using TLS.
TLS Cert FilePath to the TLS certificate file to use. Leave blank unless using TLS.

Proxy server

These settings are optional and typically only used when connecting to a PBX which exists on the internet rather than locally.

SettingDescription
AddressIP address or DNS name of the proxy server.
PortPort number proxy server uses for SIP communication on. Default is 5060

Use this table to enter up to 10 additional backup SIP registrars, with which the system can register if the main PBX/server goes offline. This is entirely optional.

The Order column indicates the order in which the servers will be checked; always configure them in the desired order of precedence, starting with server 1. For each server, enter its IP address or DNS name.

All backup servers must use the same port number, realm, expire time and transport protocol as the main server.
