SPA3102

What it can do

It has 1 FXO and 1 FXS port. That means that it can connect to a PSTN line (The Phone Company) and it can connect to (one or more) analog handsets.

It has two ethernet ports, one for your internal network and one that is intended to connect to the Internet.

PSTN fallback mode

If the SIP proxy fails, it can connect the handset(s) on Line 1 directly to the PSTN line.

Router features

It supports a few basic router features including port forwarding and DMZ passthrough. It can be a DHCP server. It supports QoS and VLAN settings.

Streaming audio server (SAS) feature

When enabled, incoming calls are auto-answered and a stream of packets goes to the caller. So the line could be used for something like listening to the output of a microphone or a radio or a recorded message.

Hooking it up

Serial number: FM600GA18536
Hardware version: 1.4.5(a)
Software version: 5.1.7(GW)
Mac address: 000E08CEB151

I hooked it up and put a static IP address on the network side. I turned off the DHCP server.

I plugged a phone into the phone jack and configured Line 1 as I would any of our other Linksys/Sipura phones (PAP2, SPA841, SPA941).

I added entries for the phone in my Asterisk extensions.conf and sip.conf files. I reloaded asterisk and then checked for registration of the phone.

asterisk -r
CLI> core set verbose 10
CLI> reload
CLI> sip show peers

It shows there with an ip address of 127.0.0.1 which can't be good. :-) I think it wants to use itself as its SIP server. I suppose that works if I can get the SPA3102 SIP server to talk to Asterisk. Then the Line 1 would make calls going through the SIP server in the device itself, and then out via Asterisk.

Another approach is to use this configuration wizard, which directly reprograms your SPA3102 and also tells you the settings to add to your Asterisk server.
