Many people already know that I dabble with Asterisk on a daily basis. Our Linux distribution of choice here at work, also happens to be Gentoo.
Now, when updating Gentoo's 'world' package base, you do get some problems occassionally. This is a downside to being 'on the cutting edge' and, it's ...

I've written a short guide on how to configure a Netgear DB834GT (and possibly other variants of the DB834) to forward a device to a TFTP server, via the router's built-in busybox/linux-based udhcpd server. I've recently been setting up a Cisco IP phone at home, and this functionality has proven ...

Update: On my last trip to the hosting facility where this router's stored, I took the opportunity to test the theory of a non-Cisco CF card knobbling the successful restart of a router. I was sure I'd checked already, but I wanted to be sure.
Thankfully, it restarted without a hitch. ...

Whilst I've been messing about with registering a Grandstream GXP2000 to our CME 4.2 server's SIP service, I've found quite an annoying problem.
The phone registers fine and can make external calls via the SIP trunk absolutely fine. The phone will also accept transfers of internal calls (ephones), but if I ...

When you're testing translation rules on a CME setup, you need to be very careful. An example of the test command:
test translation-rule 1 01234555321
Don't assume that just because there is no output from the test, that nothing has been matched. If there are no matches across any of your rules, ...

A short while ago I discussed the merits of Cisco's CallManager Express 4.0 software, over their previous 3.3 release which I had been using. It really was a big improvement, but alas there was still some functionality missing that I really required (namely the 'blf-speed-dial' command.)
So the hunt began, and ...

I haven't updated for a while, due to being really fed-up with going in circles on this new phone system, so please bare with me. What follows is some hard-learned experience (and there's certainly more of that to come) that I'd like to share with the world, as well as ...

Well, I think I might have worked out why we're having transfer problems from external numbers, to a CME SIP phone via a normal CME SCCP phone on full-consult...
Only CME 4.1 supports the command set 'voice register dialplan' - CME 4.0(2) doesn't have such a command.
And there's only one IOS ...

So in the last few days I've been playing around with a new Cisco 2811 and CallManager Express 4.0. One thing that's bugged me hurrendously, ever since I began working with CME, is the generation of config files. When I first started my job, the phones were running from an ...
