[Asterisk-Users] 499 Error on X-lite / asterisk setup

[David John Walsh]

I have a fairly simple asterisk setup - A at H 0.8 in SIP.conf:

Extentions 200 - 204 - username, password, callerid all same as extension

Extensions.conf - default build from A at H 0.8

In x-lite all spaces are either the IP address of the asterisk box or
the extension number.

On loading of x-lite, asterisk pipes up that the extension is seen

dialling anything from x-lite gets to asterisk (seen with sip debug)
however nothing comes up in the console (verbose >4) and 2 seconds
later x-lite returns an error of "499 Not Acceptable Here"

In the console I get :

SIP/2.0 488 Not Acceptable Here

The AAH was a clean install from the ISO on known to be good hardware,
and its nothing I haven't done before

Have I missed something?
