Asterisk and a Linksys SPA-941

Linksys have done it again, produced an excellent product with a build quality to rival Cisco’s main offerings. I’ve just become the proud owner of a shiney new Linksys SPA-941 VoIP hardphone.

Getting it out of the box, it looks like its come from the same heritage as many of the Cisco VoIP phones, which isn’t surprising seeing as Cisco aquired Linksys about 3 years ago. It has a solid feel to it and the buttons respond nicely, unlike by Grandstream BT-100 which feels rather (very) cheap in comparison.

The next model up, the SPA-942 comes with a backlit display and an extra ethernet port, but neither of these were a major problem for me.

Getting the phone working with Asterisk was a total doddle. I already had a sip account set up in Asterisk, so I simply plugged the phone in to the network and power. The phone got a DHCP address (which you need to lookup what IP address it gets given) and I went to the web administration page with a browser. All that had to be done was set up the username, server address and password, then apply the changes. The phone rebooted and was online with Asterisk ready to make and receive calls.

I’ll write up the configuration at a later date. I’m going to see if I can write up some instructions for doing an autoconfiguration process for rolling them out at a commercial site.
