Talkswitch 48-CA/CVA, 24-CA manual Assign phone numbers to each VoIP location

If you do not have a static IP address, you can obtain a Fully Qualified Domain Name (FQDN) from a Dynamic Domain Name Service (DDNS) provider. A DDNS matches your dynamic IP addresses to your FQDN, so that your TalkSwitch VoIP network operation is not affected by IP address changes.

One DDNS provider is DynDNS.

Visit http://www.dyndns.org/services/dyndns for more information.

Configuring TalkSwitch to act as the SIP server is described in 5.4.2.1 TalkSwitch Profile on page 164.

Example: Building on the previous example, the TalkSwitch system in the San Francisco office is designated as the SIP server. When a location initiates a call, the TalkSwitch in San Francisco will resolve the destination address for the call and coordinate a connection to route the call to its destination.

5.3.3 Assign phone numbers to each VoIP location

You can now assign phone numbers to locations in your VoIP network.

Each TalkSwitch unit with VoIP lines can support up to 12 VoIP phone numbers. Unique call handling scenarios can be configured for each VoIP number. VoIP phone numbers can be 3 or more digits in length.

TalkSwitch supports 50 VoIP location numbers (250 to 299) that permit direct dialing from any extension or auto attendant in the network. If needed, numbers outside of this range can also be added. See 5.4.3 VoIP Numbers on page 170 for details. Each VoIP phone number assigned in a multi-location network must be unique (i.e. only used for one location).

For VoIP calls made through a VoIP service provider, the service provider will assign the VoIP numbers to be used for their service.

To assist in assigning VoIP numbers for your network, use the 5.6 VoIP network administration form on page 180.

Assigning VoIP phone numbers in your TalkSwitch configuration is described in 5.4.3.1 Assign VoIP phone numbers on page 171.

Example: Continuing with the previous example, five VoIP location numbers are assigned to VoIP lines in San Francisco (251 to 255), nine are assigned to VoIP lines in New York (261 to 269), and one is assigned to the teleworker office in Miami (271). These phone numbers can be dialed directly from an extension or from an auto attendant from any location within the network.
