It's easy for customers who are not technical, it makes things super simple when I'm managing my calls with them as well! The customer service is excellent too - they're always willing/able answer questions whenever needed (and sometimes even before!). Definitely recommend this product if your business requires an inexpensive VOIP solution that does what its supposed do; make Voicemail available at all times regardless of location & time zone differences etc.. Easy-to use interface w no training required by users!! No real complaints here other than maybe some minor UI issues which can be easily resolved via support team but overall very happy so far :) Have been using these products since their early versions in 1998 till now without having problems during those period except couple glitches from past version upgrades back then only :D If anyone wants cheap voice mail services look into oomaservices like me ;).
