REALTIME - rejected because extension not found in context ''

I have tried a few different tutorials to get my REALTIME to work.

http://www.open-voip.org/index.php?title=Asterisk_Full_RealTime_example

I just need to to give temporary extensions for internal calls and messages only.

The above seams to have done the job, however no matter what i have tried, i still get:
chan_sip.c: Call from '1000' (1.126.48.224:30415) to extension '7777' rejected because extension not found in context 'from-internal'.
I followed these instructions to the letter, which the exception of changing my context from: from-sip to from-internal

However, My REALTIME user does seam to connect and register ok.

Could any one lend a hand please?

I’d suggest looking at the console log at startup to see if it has produced an error or warning that would help you. If not then you’ll need to provide what you have used for your configuration and your table and contents.
