NexVortex	Re: NexVortex 03/03/2011 - 05:44	Overall: 1.8 Price: 2 Customer Service: 1 Features: 2 Reliability: 1 Sound Quality: 3	Nice billing interface	No tech support or customer service to speak of, you leave a voicemail and maybe you get a call back. No week-end support no evening/night support. Very unreliable, down 3 times in a year and twice in 2 weeks (long outages).	As a well respected VoIP implementation company we deal with nearly every SIP trunk provider. I must say that this has been one of our worst experiences in the industry. It is NOT a business critical company to rely on. Single location of servers in a COGENT data center and no backup/redundancy. Your choice.
Conexiant	Retail maybe, not for reseller/wholesale - Conexiant 07/21/2014 - 05:33	Overall: 2.2 Price: 3 Customer Service: 1 Features: 3 Reliability: 1 Sound Quality: 3	The web gui got much butter over the last year	Reliability, CDR, support	As with many other VoIP providers, support is very poor. The issues "can't be replicated".... Eventually one just gives up. We used them for some origination services because of their easy to use GUI but reliability of the service is very questionable. We experienced a number of outages and the company's management did not do anything to rectify the situation other than admitting "an error on their part". CDR was not working fo rthe better pasrt of a year. We ordered several DIDs that turned out not to be availible (previously assigned). This is certainly not a company that can handle the needs of a wholesale client.
