What our Customers are saying?

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!

- Sean Nobles

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

- Frank Tricamo

We have been using DIDForSale for several years now as a wholesale SIP trunk provider and eFax solution. Both their service and pricing are solid and their customer service is easy to work with and easy to get a hold of, unlike other providers we have dealt with in the past. They continue to add new features and are even open to our suggestions which the larger carriers would not even consider. They provide all that we look for in a vendor and we highly recommend them.
