I have installed a vg224 voice gateway along with our cucm6.1 and have been unable to get a analog phone to work with it. The vg224 has been entered into the cm administration under gateways with sccp. I have attached a analog phone to the vg224 and configured it in the cm adminstration with a number assigned. What else am I missing to get this to work. I have only had experience with the older vg248 which was not ios based.
