We are VOIP products company with 5 years' history, but we have a very strong team group. Many team members of us used to work in HUAWEI and ZTE for almost 10 years. At present, we have 20 engineers who take in charge of products development. All these products we have now are designed and invented by ourselves. We are not resellers who sell their products with an unchangeable firmware. Our products will update from time to time. We will add new functions into the firmware when they come into being. I am sure and proud to say we have very powerful technical strength. We will try our best to solve any problem that our clients meet.
