I'm running v.2.1 for the ip communicator. Every since I upgraded from 2.02 I have had a lot of complaints from users stating that they can't dial 800#. all other numbers work. If I un-check the "Optimize for Low Bandwidth" it works. user are able to dial toll free numbers. the problem is this can only be a temporary fix. I need a more permanent fix. Can any give me any insight on this?
