How can the bottom line be anything other than, "do I have the services I paid for?"
One more bottom line:
"Does the customer have a disaster recovery plan?"
Voip is a wonderful service saving us $$$. But IMHO the user needs to have a disaster recovery plan. Having at least one backup voip provider and a cell phone is always a good part of a disaster recovery plan.
Your internet connection could also fail so a backup internet connection should be considered. Your provider can have geo redundancy but that won't help you if your internet connection fails.
Also, an UPS must be considered as mandatory for a responsible voip user.
