Take a pen and paper and write down exactly what you will say. Then call them back. This way you will make sure you say what needs to be said, you will not forget to say your name at the end and also share your phone number.
Avoid telling your prospect what to do. You'll make returning your call seem like a chore or, worse, a demand. This should feel like a mutually beneficial relationship -- one in which each party wants to call the other back -- unprompted.

My number is [phone number]. I’ll also follow up with an email tomorrow. I look forward to hearing what you think. The key to making a script work is to practice. You can’t read it line-for-line, so it’s important to work out the kinks before you place your call, including: Your name Your reason for calling The benefit of calling you back Your contact information Your promise of a follow-up email
Ive been saving my grandmothers voicemails for almost 8 years now and when i went to upgrade my phone, i almost fainted when the rep told me they were going to be erased. Thanksfully he put us in touch with a company called http://www.voicemailsforever.com and they ended up much cheaper than the one you suggested above. i think your readers would benefit because they do it for so much less.
