I'm not sure how credible a post on about Lingo DSLReports should be taken in the grand scheme of things. but the idea that some of these issue gives me a chance to talk about the customer service experiences I've had with Vonage, Skype, iConnectHere, AT&T and Voice Pulse to date.
Vonage--Mixed. The support is a mix of offshore and domestic. Most of what needs to be done can be done by email, and while that's good for techies, it's not good for the mass market. My experience with the softphone and its platform issues was a tad funny, and took the intervention of the Vonage PR team.
VoicePulse--Overall the support is good, but they have limited hours and up to now it has been primarily by e-mail. The company plans to add real time live support. When I did talk to their staff they were very knowledgeable, but it took the CEO/Founder to help on the Zyxel WiFI phone, which works great with VP.
iConnectHere--Great support. I had an issue with the drivers for the Clarysis phone and one of my PC's. They were able to get me to the right person and the problem was explained and fixed. The support was by email, and then phone.
Skype--My account balance was off depending on which PC I was on. Email rapidly explained it was a bug. So far, there has been no need for tech support.
AT&T CallVantage--So far my one need to call them, dealing with a bug for a day when the Do Not Disturb has been the best experience of all the companies. Rapid answer to the call. A knowledgeable support specialist. A call back after it was fixed to make sure I didn't have any problems. I like the human touch.
