Hi Klaus. I added the lines you mentioned above into ser.cfg and restarted 
SER, but dialing 12341234 returned a 404 Not Found to my softphone. I 
wasn't sure where those lines were supposed to go, so I tried them in a 
few places, all with the same result.

At the moment I have a very basic ser.cfg which I have attached to this 
email. When you have a minute, if you would't mind taking a look through 
it and letting me know what else needs to be done to get aliases working, 
I'd greatly appreciate it.

Cheers!
