We signed up to Xinix in June, almost 3 months later and we still don't have a stable VOIP platform, to the point whereby my staff refuse to use the phones at all and will only work from their mobile phones. Upon the advice from the salesman we purchased a new 2nd fibre line to provide extra bandwidth to ensure we had good call quality. The 1st router we received didn't work. The 2nd one arrived a week later and the call quality is really bad - clients complain they cant hear us, etc. The router needs restarting twice a day (at least) as the line randomly drops out completely and wont come back up without a restart. BT have been out several times, originally they diagnosed a fault, now they are saying their are no faults with their hardware and that it MUST be with the software, router or handsets. The XINIX app crashes very frequently, and for no apparent reason we are often blocked from making international calls despite paying extra for international calls (says "call forbidden"). Your tech support guys set us up with direct dials, which we used for over a week only to find out that if a customer dialed a direct dial it would not connect to our phones due to not be configured properly. This made us look like a scam / telesales business. I have reported every error and to date we are no further forward. My business has suffered terribly. The salesman that sold us the system is now telling us we are tied into our contract and to contact OFCOM. We are happy to keep the 2nd fibre line and also to pay in full for the Grandstream handsets but we simply cannot continue with the VOIP service - it simply does not work for us at all. The direct debit is cancelled so watch this space!
