I will briefly outline the situation currently and I would like your opinion on the best move for us.
Currently we are running a Trixbox server with VoicePulse and Teliux VOIP services. We have two providers, because we were getting fuzzy calls or dropped called constantly. Having two providers, regardless of what one we use, doesn’t help. We have done many things, such as changing servers, changing ISP’s, having dedicated DSL internet connection only for voice traffic, and nothing has helped. Staticy “are you on a cell phone” type calls both outgoing and incoming.
Something is telling me that the VOIP technology just isn’t there yet or we are overlooking something extremely simple and stupid. I have yet to find this out and cannot continue to have an unprofessional sound on the phone.
We are using Linksys SPA 941 phones and a Cisco 7940 SIP. We LOVE the features Trixbox (Asterisk) offers and the versatility but the reality is that our voice quality is terrible and has to change. So we are in the midst of going to be changing to analog phone lines.
My question really is if we go this route, what would you recommend? There are only three of us here in the office, so I was thinking of bagging the whole Asterisk idea and going with a simple pure analog NEC or Avaya or Talkswitch phone system. Our entire phone system, including phones, would basically have been a waste and would need to be sold.
Another alternative is getting a two or four port FXO card for the Asterisk box to convert the analog signal to digital format. Problem with that, is that I have heard from nearly every Asterisk expert I have talked to that the technology isn’t there and you’ll still get really bad echo occasionally from the analog to digital FXO conversion.
What is your opinion(s) on this matter? I don’t want to purchase a $1,000+ FXO PCI card for the Asterisk computer and have echo. I would rather spend $1,500 to $2,000 on an entire new phone system that we can use true analog with. Although we will be missing out on some yummy Asterisk features.
