We are at this point a small VoIP integration partner and have a current install base of around 15 sites with Asterisk based PBX's. These range for 5 through to 30 extensions per site.
My issue with WXC is that every one of these customers are using ADSL (dedicated) to terminate SIP trunks (ITALK). To be honest we have had some issues with some of the ADSL connections, but very few.
My grief with WXC is that;
1. They wont supply business trunks across ADSL? The strange thing is that they seem very happy to provide via UNS which is delivered over EXACTLY the same medium as ADSL. Telecom will tell you that they monitor UNS and this is the reason that WXC say they will allow it. I have had 1st hand experience at this and can tell you it is a load of rubbish.
2. If the argument is one of capacity, we were happy to take dedicated ADSL circuits with WXC which should mean at least 700kb of outbound traffic is available. If the circuit has a capacity issue, does this mean that WXC has a overloaded termination into to ADSL world??? If this is the case is WXC saying that their own ADSL service is substandard?
3. They will only sell a minimum of 5 DDI's. With ITALK I can get as many concurrent calls as my bandwidth will allow @ $10 per month (per trunk / DDI). Many small companies don’t want and don’t need lots of DDI’s. What they need is call concurrency. This concept seems to be foreign to the people at WXC!
We really wanted to do business with WXC and were looking at transferring all our VoIP customers across. But because of the company’s ill conceived ideas and inflexibility we will be unable to.
WXC seems to be a company more focused on technical excellence rather that satisfying customers needs.
I do know that other MAJOR ISP's will be entering this market and I do feel that these cause WXC major damage in this market.
My advice to others looking toward business customer solutions are that WXC are way too hard to engage in a successful relationship and to look elsewhere.
These are my experiences and I have held many discussions with the WXC team and are disappointed to have of come to this conclusion.
