I have a site that is moving and they currently have POTS lines and they are getting an new phone system (FXII) and it will have a Voice T1 PRI from MCI. They want to keep thier existing main number. I want to move the LEC service and have the main number ported to the T1 on the same day. I will have about 30 days before this is to happen. Is there a easy way to do this? I have had problems in the past with porting, paths, etc?
