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.

At OpenPhone, we used Fiverr and definitely recommend this service. It was quick, affordable, and got the job done. For our project, it took over 36 hours of work between submitting the script and getting the final result. The cost was roughly $115 for the final project.
