In addition to changing the way you dial local calls, all services, automatic dialing equipment or other types of equipment programmed to make 7-digit calls need to be reprogrammed to support 10- or 11-digit dialing.

Examples include:

• Call forwarding settings
• Fax machines
• Fire or burglar alarm and security systems or gates
• Internet dial-up numbers
• Life safety systems or medical monitoring devices
• Mobile or other wireless phone contact lists
• Private branch exchange phone systems
• Speed dialers
• Voicemail services and other similar functions
