Has anyone heard of any recent problems with Cingular and EC500? We've been using EC500 for about a year now when we recently lost caller-ID on station calls. In other words, when someone calls my station and I pick it up on my cell phone, it just displays "Unknown". Our PRI trunks are sending the correct ANI on all other outgoing calls. Interestingly, this is only the case with those of us using Cingular for our wireless provider. We have another group using Nextel and they don't have this problem.
