But don't listen to us, listen to our customers.

Sipharmony is awesome, as is the owner, Alan.  They are always right there when you need them!  Even after hours, when you leave a message and hope they hear the message tomorrow, you get a call back within minutes.  Customer service is job One behind their dependable phone service!  Sipharmony just happens to excel at both! Happy customer from Austin!

Dr. Wheelock

Pediatrician

Prior to Sipharmony we had spent a ton of time setting up and testing out 3 of the biggest VoIP providers available. We constantly had issues with answering calls as well as reliably sending/receiving SMS via their apps with all 3 of these providers. This made retaining our newly trained and hired receptionist impossible. On top of that, reaching out for support from these big companies was an absolute blackhole for our time. Alan immediately helped us get up and going and most importantly with reliability! He handles every single part of our phone system for us and is very prompt to make any changes anytime we need it. Such a relief and all of this for a cheaper price then the big guys. Don't typically leave reviews but this one was a life saver, would absolutely recommend Alan to anyone.

Sipharmony made our change from traditional landlines to VoiP very seamless for our group of pharmacies. They are always very responsive when we have questions or need to update anything with our system through email or even Discord. I would recommend them if you are looking to change VoiP providers or wanting to get away from landlines.
