PBX Centre

A PBX Centre is a special account in your Octopus IP-PBX Domain. This Account uses a special pbx Real-Time Application to answer calls from other Accounts in the same Domain, as well as calls from "external users" (Accounts in other Domains, accounts on other SIP servers, PSTN users calling via gateways, etc.)

The PBX Centre allows your Domain users to collaborate on call processing.

If your Domain uses PSTN gateway(s) for incoming calls, you may want to configure those gateways to direct all incoming calls to your PBX Center Account.

You can also use the PBX Centre Account address as the "public SIP address" of your organization.

When your IP-PBX domain is configured a PBX Centre Account pbx in the Main Domain is created, and it creates the 200 and conference aliases for that Account.

Remote SIP users can access the PBX Centre by calling sip:pbx@your.domain.name, and users with Accounts in your Domain can access your PBX Centre by dialing 200 on their SIP phones.

If you are a Server or a Domain Administrator and you want to create an alternative PBX Centre:

• Create an account to be used as a PBX Centre.
• Change the Account Real-Time settings so the pbx application is started immediately when a call comes in.
• Grant the CanImpersonate Domain Access Right to the PBX Centre Account, so the application can place calls on behalf of your Domain users.

When the PBX Centre is called directly (using the pbx name or the 200 Alias), it starts the Auto Attendant application.

Other PBX Centre functions can be invoked by accessing the PBX Centre via alternative names. By default, the OctopusIP IP-PBX router directs all calls to 7nn names to the pbx Account (where nn is a 2-digit number).

When the PBX Centre application starts, it checks the address used to call it. If this address (the "local part" of it, the part before the domain name) is a 3-, 4-, or 5-digit number, the application uses the last 2 digits as the requested function number. The documentation below assumes that your Domain uses the 7nn@domainName address to invoke the PBX Centre function number nn.

The PBX Centre application requires authentication for most calls coming from its own Domain. You may need some exceptions from this rule. For example, your in-house gateway may send incoming calls to your PBX Center using the From:<sip:gate1@mydomain.com> address.

To accept these request without authentication, create the ExternalGateways group in your Domain and include the gate1 name there.

The gate1@mydomain.com must be routable: for example, you may want to create a gate1 Account, or, more likely a gate1 Alias for one of your existing Accounts.

If a request is not authenticated, the PBX Centre processes it as an "external call".
