Planning Your Configuration; Case A: External Incoming Calls Are Answered By A Receptionist - Avaya one-X Quick Edition System Administration Manual

The DNS server on the telephone converts the domain name to a routable IP address. If
required, you can specify the host IP address of the SIP proxy/registrar server instead of a
domain name when you create the service provider configuration.

Planning Your Configuration

After you receive the required service provider configuration information and SIP identities from
your service provider, you can configure the settings you need to support SIP interoperability.
There are two high-level steps to configuring the network:
1. Define the SIP network configuration. See
page 61.
2. Assign SIP identities. The assignments will depend on how your office is set up:
Are all calls answered by a receptionist and redirected manually? If so, see
External Incoming Calls are Answered by a Receptionist on page
Does everyone have a direct line? If so, see
page
Do you have a sales or support group that takes calls on a dedicated line whose
telephone number differs from that used to call the receptionist? If so, see
Incoming Calls are Routed to a Group on page
Should all incoming external calls be answered by the Auto Attendant feature, which
prompts callers to dial an extension number? If so, see

redirects all incoming calls manually, you need to configure one SIP identity that corresponds to
the receptionist's extension number (see
receptionist's telephone would be responsible for handling all incoming calls.
To enable all telephones connected to the network to make outgoing calls, you assign the same
SIP identity to those telephones (see
outgoing calls easy, the "global" option lets you select all of the telephones on the network.
In summary, you would specify information similar to the following values when you create the
SIP identity, where extension number 200 belongs to the receptionist, and the Global setting
refers to all of the telephones connected to the network:
