Thanks for all reply's. Calls were being blocked by BellSouth due to my switch sending incorrect numbers. Change options in send number to ext. only and it works.
What they (bellsouth) want admit to is that something in the translation was changed. This pri was installed on 4-8-04 and worked ok until 4-22-04. I had not changed any options in the pri setup during this time.
Thank all
Doug
