I have a Phone 8 Card in my IP Office 500 V2. When I go to change the extensions on my phone 8 card, brand new...it doesnt allow me to switch off of port 1of this card. I can change the extension of this port, but none of the others, it just snaps back to port one even if I click port 2, 3, etc. Anyone else having this issue? I even tried the extension renumber tool, and i selected the whole 8 ports for the range, just changed the first one, but none of the others. Thoughts???....so odd
