Configuring Voip Failover To Pstn - Linksys RTP300 - Broadband Router With 2 Phone Ports Administration Manual

Gateways 1 to 4 can be specified in a dial plan with the special identifier gw1, gw2, gw3, or gw4.
Also, gw0 represents the internal PSTN gateway via the FXO port. You can specify in the dial
plan to use gwx (x = 0,1,2,3,4) when making certain calls. In general, you can specify any
gateway address in the dial plan. In addition, three parameters are added that can be used with
call routing:
• usr—User-id used for authentication with the given gateway
• pwd—Password used for authentication with the given gateway
• nat—Enable or disable NAT mapping when calling the gateway
The following table lists some examples.
Example
<9,:>xx.<:@gw1
[93]11<:@gw0>
<8,:1408>xxxxxxx<:@pstn.Linksys.com:506
1;usr=joe;pwd=joe_pwd;nat>
<8,:1408>xxxxxxx<:@gw2:5061;usr="Alex
Bell";pwd="anything";nat=no>
You can set up multiple PSTN gateways at different locations and configure Line 1 to use a
different gateway when dialing specific numbers.

Configuring VoIP Failover to PSTN

When power is disconnected from the SPA3102 or AG310 device, the FXS port is connected to
the FXO port. In this case, the telephone attached to the FXS port is electrically connected to
the PSTN service via the FXO port. When power is applied to the Linksys ATA device, the FXS
port is disconnected from the FXO port. However, if the PSTN line is in use when the power is
applied to the Linksys ATA device, the relay is not flipped until the PSTN line is released. This is
done so that the Linksys ATA device does not interrupt any call in progress on the PSTN line.
When Line 1 VoIP service is down (because of registration failure or loss of network link), the
Linksys ATA device can be configured to automatically route all outbound calls to the internal
gateway using the parameter listed below.
