Caller ID Spoof (On Demand)
Using Asterisk and a VoIP provider you can set your caller ID to anything. I leave mine set to my real number, but when I had a cell phone I would occasionally change it to my cell number. The most common use for this type of feature is if you have a business and you do some of your work from home. Instead of making that occasional business call using your home phone number it might be more professional to change it to your business number before making the call. Obviously this feature also has great potential for abuse, but I figure that anyone who takes the time to setup their own PBX should be mature enough not to abuse caller ID and if not they would be able to do it without any help from this article anyway.

Public Key Access to OpenWRT
I allow SSH and only SSH into my router via WAN. I have the web interface and all other ports that don’t have specific forwards blocked for obvious reasons. When you install OpenWRT it automatically blocks everything from the WAN side, so this doesn’t require any configuration. Although if you are like me and you require access to your network from outside then you will need to make some changes.
You don’t want to have password authentication on the WAN side or it is possible to get compromised by a brute force attack. The solution is to implement public key access.

SIP Scanning and VoIP Security
A few months ago after I had setup my Asterisk box I started receiving strange calls from people in Colorado and started to check my call logs. I noticed that the night before someone had made calls from my box to many different numbers in succession. xxx-xxx-2401, xxx-xxx-2402, xxx-xxx-2403, etc. I knew that my box had been compromised.
I had set weak secrets for my extensions and they were able to brute the secret and start making calls from my machine. I immediately changed all the secrets and have not had a problem since, but this article will show you some tools that can be used to test your own box and some settings that should be changed in order to secure it.
