David Brian Moore
DIDforSale support provided excellent technical support and a very timely response to my support issue. The communication and explanations of how and when the issues would be resolve were clear and concise. For this issue I could not have been more pleased with the resolution. Thank you DIDforSale(Sam!)
Working with DIDforSale has been a great pleasure. This is our first entry into the SIP service space and they have been very helpful in working with us to get our offering up and running. Questions and (issues, usually on our side) have been addressed timely and professionally. We look forward to working with them for the foreseeable future.
DIDForSale is a highly valued partner for our business. We have been using them for a year and a half now and have had a great experience. Their SIP Trunks work with numerous platforms which makes it very easy for me to move trunks around in my own infrastructure for testing or to be responsive to our client's needs. For an enterprise class SIP Trunk solution at small and medium business prices, look no further than DIDForSale!
We've had DIDs from DIDForSale for many years now, and I have to say that their DIDs always work; but, more importantly, the quality of service these guys provide is top-flight! They respond to our support requests in an hour or less. Of course, we don't need much support, as things just work, and their web-portal lets you do pretty much anything you need to do. But if you have a problem (usually, you've screwed something up with your firewall), they are QUICK to respond. When we ported some numbers from Comcast, Comcast was TERRIBLE in the whole process, but DIDForSale worked closely with us and babysat the port through for us. I can't say enough about their customer support! I highly recommend DIDForSale for everything VOIP-related!
Been using DIDforSale for a number of years now, very responsive and proactive staff. Needed a different config for a WAZO install, 3 of us got on a phone call and promptly had it figured out. I like the new Account Interface tools. Very competitive pricing and many free test numbers for config testing. There is no need to go anywhere else. FIVE STARS
