I fax about 2-3 pages each month and have never had problems on Vonage. So before signing up for Voipo, I asked customer support whether I can fax on Voipo. Their response: While it's not a feature of Voipo, faxes can be sent.

So I signed up and tried several test faxes which went fine. I sent about 6 faxes successfully since singing up in Feb 2009. Then they had the Network issues that interrupted service for many customers. Well, whatever they did to fix the network issues, I now get echos on voice and CANNOT send a single FAX. The echos I can tolerate, but no fax is very inconvenient for me.

So I called tech support and was told that while it's not supported, if I open a ticket, someone can at least take a look to see if the settings on my device is optimized. This seemed reasonable to me. I send the ticket and here's the response:

> Hello,
> Since we do not fully support fax and we do not recommend that our customers to use our service for anything except voice service, there's no troubleshooting we can offer for your faxing issue. Faxing is pretty much hit or miss on VoIP service due to the communication over the internet and up time is never guaranteed. Let us know if you have any questions or concerns. Thank you.

So not only do they not support fax, they won't help you in any way to troubleshoot. And their recommendation to only use it for voice seems inconsistent with the information that I received before signing up. I guess it's not worth their time anymore to help out their customers. So anyone considering faxing on Voipo, don't repeat my mistake and go with another provider.
