When you hear the Dial Tone, call into your landline or office voicemail box. The rule of thumb is when you hear the Voicemails Forever dial tone, then follow your phone's instructions to listen to your voicemails remotely. This will vary from carrier to carrier and phone to phone. You may need to call your phone networks customer support for updated instructions.
When you leave a voicemail do not use your full name because that immediately raises a red flat that you are a salesperson making a cold call. Instead, say your first name only followed by your company name. This will make your customer feel that you are much more familiar with each other than you really are. Saying your last name would defeat the whole purpose of demonstrating familiarity.
