I have cancelled my service.
I have cancelled my service. Incoming calls would NOT connect. Outgoing calls worked about 50% of the time but a LOT of echo on the connection. The customer support only ok. The cost is high for what you get.

Every month, I experience phone calls being dropped and "all circuits are busy" messages for outgoing and incoming calls. Although their customer service is satisfactory, I am really disappointed with the app.

Tresta is good to use since it allows me to use my personal phone and have my business line going out. I do have a couple issues. I do make a heavy amount of out bound calls, and once a week or every other week, the systems goes down for at least an hour. The day is random, but it's usually between 5pm and 7pm PST. I tend to make my calls between noon and 8pm PST. So when this happens my productivity goes to nil for that time period. Restarting my phone doesn't help and I have tried to call several different numbers several times. I can still make calls on my personal number, but having Tresta is so I customers don't have my personal information. There is no "troubleshooting" that addresses this. The other part is off hour scheduling doesn't work that well as I still see calls coming in no matter what the time of day. Whether I am at work or not. Those are the reasons I don't give a 5 star rating.
