Several months ago, I was subscribing to a VOIP provider on a two year contract.
About four months before the contract was up, the audio on my end became so garbled that I couldn't understand my callers or the person(s) I was calling.
I asked my VOIP provider to troubleshoot it. They tried for a couple of months. They had me bypass my Cisco 871 router and connect my PAP2T VOIP device directly to my cablemodem. It wasn't great, but the quality was much better.
Then they pointed the finger at my Cisco router. I asked them to troubleshoot it. They refused. They said they will troubleshoot Linksys and several other SOHO routers but they would not support Cisco (which IMHO is the best).
After two months with no resolution, I negotiated a deal with another VOIP provider who assured me that they would support my Cisco router and that same VOIP device. I was assured that they'd get this working for me.
So we configured the PAP2T up for the new service and submitted porting requests for my toll-free and my home numbers.
The quality was the same. They'd troubleshoot it for a day or so and then drop it. I'd have to call again every few days to make them pursue it further. I pointed out to them that they promised me they'd get it working.
I decided to get another Cisco Smartnet contract so we could get some help from Cisco TAC.
Cisco TAC went over that router with a fine tooth comb. They could find nothing wrong.
So I asked the new provider to troubleshoot again. They never isolated anything. I even gave them access to my Cisco router so they could look at the configuration.
After two months with no resolution, I purchased another of that same Linksys PAP2T VOIP devices. It was strictly a shot in the dark (which is not the way to troubleshoot (buy this and replace it. If that doesn't work, buy that and replace it, etc.)).
It cleared the problem immediately. Neither one of those providers could isolate the problem and it took four months to resolve it. If they had determined the device was bad in the first place, I could've replaced it a lot sooner.
It is clearly a disgrace to the VOIP providers' industry.
I contacted my old provider (who had charged me for the two months that I switched before the end of the contract). I told them about the resolution and insisted they refund the two months of charges since they failed to identify the unit as being defective.
Just a few days later, those charges were refunded to my charge card. At least they did that much.
So far, the new provider has not charged me for service. We'll discuss those first two months if they charge me for them.
