I am VOIPYOURLIFE customer since November 2006, that is close to five months now. Price is very good, free calls to many countries in Europe with sound quality usually better than calls within the US (strange but 1). Reliability is good, features good enough for me even with crippled caller ID.
One thing which makes me thinking about quitting their service is while voice quality on my side is always good to excellent - other parties that is people on the other side of the phone including myself when trying to call home - often complain about extremely low volume of my voice. The pattern is that connection usually starts with very low volume on their side and gradually improves reaching - after one minute or so - levels still on the low side but acceptable.
VoipYourLife customer service is - like some other people described here - pathetic. They do not even know how to introduce themselves when picking up their phone. You never even hear "How may I help you?". They mumble something like "Customer Service" and that is is. My explanations are always summarized that my Internet service does not have sufficient upload speed and too many packets are lost. While I can accept, that my service could probably be better I do not understand how my other VoIP line, which is VONAGE can always work without problems at all. Initially, when I signed with VONAGE their service was terrible, I even closed one of my accounts, paid the early termination fee and moved that account to VoIPYourLife. That with the second VONAGE line I really took my time, spend endless hours on the phone with VONAGE Customer Support, my case was elevated to the LEVEL III or IV of their CS, their replaced my adapter, possibly moved my account to another server and now everything works like a charm ALWAYS. That means the sarvice CAN work if you take a time to do it properly. So far VoIPYourlife is not willing to go beyond being rude and blaming my Internet connection.
To summarize: my VONAGE account as of today works MUCH better than VoIPYourLife (no free calls to the countries of interest in Europe though). My SKYPE works well. My Internet connection is fiber-optic cable (Verizon FIOS) with upload speed consistently in the range of 1700 - 1800, MUCH faster than what is required for VOIP. I have Hawking Broadband Booster (HBB1) installed to shield my connection from HTTP/FTP traffic. I have never heard any complaints of my respondents if the call was made/ answered via their PC2Phone soft-phone. Yet they are unwilling to even try to exchange my adapter to another one on the grounds that this adapters AGC (Automatic Gain Control) may be defective.
Now I have two choices: shop for another VoIP provider or purchase my own adapter.
While I agree VoIPYourLife may be considered for a low price, free international calls to many countries, overall service reliability and probably can be made to work since they allow BYOD devices on their network, but do not count on their Customer Service at all. Just sign in and if you can make it to work right - good for you. If you can't - look somewhere else.
