Remote Voicemail Checking
This feature allows you to call your wireless number and check your voicemail messages from another phone. This is useful both for when you don’t have your cellphone and for when you are traveling outside your coverage area.
This also allows you to dial your desk phone and check your work messages from your cellphone. By keeping yourself up to date with this feature, you have your entire call log from your primary phone on any device, so long as you have your voicemail PIN handy.
