VoIP Cookbook: Linksys SPA9000 Configuration
The way Linksys SPA9000 operates is somewhat similar to other Linksys VoIP equipments. To configure Linksys SPA9000, we need to have:
- information on IP address for both WAN and LAN ports.
- SIP account of a provider in the internet to allow SPA9000 to register itself to four different SIP accounts.
- Number allocation for extension lines of the PBX to SPA9000 to provide address up to 16 telephone numbers automatically.
Numbers allocated for each extension are specific, distinguishing an IP PBX from other VoIP appliances. Normally, a typical VoIP equipment does not provide telephone number allocation. So if you want to connect your conventional phone to Linksys SPA9000 through the internet or WAN port, the first thing you have to do is find the internet/WAN IP address of Linksys SPA 9000 so later you will be able to configure using the web, by doing the following steps:
- Press “*” on the conventional telephone keypad repeatedly until you hear a man talking through your telephone.
- Press “110#” and listen carefully to the SPA9000's IP address given by the man. Write it down so you dont have to memorize it.
Another easier way to obtain the IP address is to go into the Ethernet/LAN port. The IP address of SPA9000 ethernet LAN should be 192.168.1.1 by default, that is, provided you have not changed the settings.
The next step is to configure your PC IP address so it will match that of Linksys SPA9000 so you will be able to do the configuration through the web. Go to PC and match the PC's family address to that of SPA9000. Go to Start menu, control panel, network connections, local area connection, internet protocol (TCP/IP), and properties.
Now you will be able to log in to Linksys SPA9000's web interface from your PC via http://ip-address-spa9000/.
The first menu you will find is the status of the Linksys SPA9000.
In the WAN setup, we get two options:
- Using a static IP (requiring IP address, Netmask, gateway etc.)
- Using automatic IP (connection type should be set to DHCP).
In general, the IP address allocation method used in a WAN normally is dynamic. However, for a softswitch, it is recommended that you set the IP address allocation to static in order to make it easier for non-Linksys SIP client to register itself to the softswitch.
In the LAN Setup tab, we can configure the following:
- whether NAT/Router in Linksys SPA9000 should be activated or not.
- IP address. Put 102.168.1.1
- Netmask. Put 255.255.255.0
- DHCP Server for client in LAN
We can also configure the IP address to be allocated to a specific MAC address.
