When you sign up for Vocalocity it states "cancel when you want" & "no cancellation fees" While Vocalocity service is not completely bad, certain features never got set up correctly. Auto attendant is difficult to adjust if you need a change, phone app never worked, several of the Cisco phone features don't work because of programing etc. Decided to move to Nextiva better tech support, features and for about the same price. Porting got rejected by Vocalocity and in a customer service call, the Tech explained that the faxing is handled by EFax (a J2 Global company). In order to get my fax number back, I must pay an additional $100 "Porting Out fee". They are happy to release all my other local and toll free lines I brought into Vocalocity, but the fee is an EFAX terms of service issue. We signed up my phone service with Vocalocity that explained that fax service would be provided in our account. Calling Efax, explained I could transfer my account away from Vocalocity to a EFAX "consumer account" for $16.95/month but would still have to pay a $40 cancellation fee to get our fax number back. Looking at Google, hundreds of J2 Global customers are complaining about being charged for service long after they cancel, and that they are exempt from US FCC rules. So we don't want to give them our credit card - even for a month.
Our business has had phone lines for 22 years and this is the first time we have ever had to pay to get our phone numbers back. Yes, Faxes are obsolete but many customers still use them for documents and POs so we still need to receive them.
If their is a Class Action Lawsuit filed against Efax and/or Vocalocity (now a Vonage Company) we will be first in line. Vonage should protect it's customers from 3rd party vendors partnerships it sets up when they go bad. As I said above, I am not completely unhappy with Vocalocity's phone service BUT this incident, charging us to get our phone number back is completely unforgivable. Unless this is resolved I will tell thousands of my current and former customers NOT to use either of these companies (J2 Global and Vonage)

The initial problems they blamed on prior provider. Then they blamed it on the phone. Neither was the source of the problems.
Their problem solving capability is very weak. They had problems finding capable techs. Resulting in the need to transfer calls. Calls and email to Vocalocity were often ignored. Although the quality of calls I made were good, the quality of calls I made to Vocalocity were poor.
I experience extended and intermittent periods when I could not make or receive calls. There were even long periods when callers could not leave messages.
Their philosophy is; the customer is always wrong.
