Wassim Khan

I started working with Welco Infotech in November of 2016. These guys were very helpful getting me started. I had no idea what I was doing and they basically walked me through the process of setting up. I email them a question or call, I always get an answer, or an email back. The rates are great. It has been a pleasure doing business with you guys!!!

Strongly recommend. 5:25 PM Working with Welco Infotech 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.

I have done business with these folks for at least three years without incident – which says a lot! They are technically very savvy. They are also very knowledgeable and helpful with VoIP in general. You won’t go wrong placing your trust in them.
