The SPA-3000 features VoIP adapter functionality found in the SPA-3000 with the additional benefit of an integral connection for legacy telephone network “hop-on, hop-off” applications. SPA-3000 users will be able to leverage their broadband phone service connections more than ever by automatically routing local calls from cell phones and land lines to a VoIP service provider and vice versa.
A typical user calling from a land line or mobile phone will be able to reduce and even eliminate international and long distance telephone charges by first calling their SPA-3000 via a local phone number or by using a telephone connected directly to the unit. The advanced authentication and call routing intelligence programmed into the SPA-3000 will connect the caller via the Internet to the far end destination with security and ease. Using the SPA-3000 at the far end, calls can be answered immediately or further processed as a local call to any legacy land line or mobile phone allowed by the SPA-3000 dial plan.
If power is lost to the unit or the VoIP service is down, calls can be sent to a traditional carrier via the FXO interface.
NOTE: We have seen instances where installing the SPA-3000 behind a firewall which blocks ICMP packets causes problems with registration. Try turning off any ICMP blocking on your firewall.
You must first determine what IP address it received. To do this, you need to pick up the phone attached to the Line 1 jack and
dial: **** (four asterisks)
then dial: 110 #
and you will be told the IP address of your device
(e.g. 192.168.0.100)
Go to any browser equipped computer on your network and enter the address:
http://<IP ADDRESS>/
(where <IP ADDRESS> is replaced by the address that was given to you in STEP 1).
Click on the "Admin Login" button near the top right side of the screen, then click on the
"Line 1" tab.
