Why I Love Kamailio
Posted . ~6min read.
If we haven’t met yet, my name is Fred Posner. By day, I’m a VoIP Engineer and a baker (yes, a baker).
Since I was a kid, I’ve loved telephones — everything about telephones. Dealing with phone companies and carriers started to eat away at that love… but VoIP brought it back.
One of the products I get to work with is Kamailio.Many of you have never heard of this product.
Even more cannot pronounce it.
In a nutshell, Kamailio is an open-source SIP server. Now, if you’re not a techie, or know VoIP, then…

Literally.

I just played with a solution from OpenCNAM that was pretty freaking simple. There’s a negative — it ain’t free. The cost is nominal… $0.004/lookup. That means that $10 will get you 2500 lookups.

Posted . ~5min read.
Ok, if you use Asterisk (or a Do It Yourself type VoIP service), you sometimes do not receive the CNAM (think Caller ID with Name data) from your carrier. Well, since geeks like information and anything “free,” there’s a simple way to use the internet to do a reverse number lookup query. So, if you’re a technical type, keep reading… otherwise, non-geek posts will return very soon.
