The full configuration of dnsmasq it’s out of scope for this doc, but in a nutshell you need these in your dnsmasq config: In my opinion, if you’re going to be running a Cisco IP phone on your network you’d be better off moving all DHCP to dnsmasq. If you later re-enable your original DHCP server, say on your router, then you will need to configure it to give out the address of the dnsmasq TFTP server and disable DHCP on dnsmasq. This will simplify the process of getting the phone to find the TFTP server, since with dnsmasq it will all be automatic. You should also (temporarily) disable any other DHCP servers on your local network so that dnsmasq is the only thing offering DHCP addresses. It’s a small and full featured DNS server which also includes a DHCP & TFTP server which are easy to configure and it’s almost certainly packaged for your distro.

Q: Is a lot of the information on the web about how to set up the 7941 wrong?Ī: Yes. And assuming you already have Asterisk set up. If you’re comfortable with Linux and a few command line tools. You need to flash the correct firmware though.Ī: No. You need to load the SIP firmware (the focus of this post) or chan-sccp (out of scope for this post but I’ll check it out at some point).Ī: Yes. Q: Does the Cisco 7941 work with Asterisk?Ī: Yes. Since these devices are no longer supported many companies will be getting rid of them (or probably already have) so there should be some bargains to be had for phone geeks. A testament to the good build quality of these phones, and perhaps the previous owner’s careful handling. These phones went End Of Sale in January 2010, so even if mine was one of the last phones to roll off the production line it’s still about 7 years old but it’s still working perfectly. This is a phone which was £400 when new (some time around 2004) but can now be picked up for about £10. Someone seems to have hosted the files here: Įdit 2: Looks like the tinyupload file has gone missing too. Edit: I heard that Cisco have now removed the SIP firmware from their site.
