Possibly a thick question.
I'm trying to set up a Gradwell (or Onecom now I suppose) extension as an alias to an 'External SIP/IAX2 URI' and forward calls to an A&A number by entering
sip:+44XXX...@voiceless.aa.net.uk in the 'Destination box' on the Onecom 'Aliases' page.
After the normal 20 minute wait for the Gradwell system to update itself it's not working.
Should it work, or have I got the wrong end of the stick - or just done something wrong?
Thanks
Andy
