Yes, it's a SIP trunk. I just can't seem to get this working. It's becoming very annoying! I've gone so far as to delete the trunk and recreate it (twice) with the same results. I' starting to think that I should just create a new account and see if that works

. I'm really starting to run out of ideas. But I may put any drastic measures on hold as the new version of Asterisk@Home is due to be released on May 30th and will require a reinstall anyway. I'll see if I still have the problem after the upgrade and if so will report back.
