We own several VOIP LTDs. It took us a while to get around to VOIZEE. Learning curve was minimal and we were able to implemented easily to our site. The more challenging setup was Twilio's integration, but that's because Twilio's requirement for registering numbers. That's outside the scope of VOIZEE as their integration with Twilio works flawlessly. Like most apps, features always have room for improvements. But the team took my suggestions well into their future roadmaps. This can easily replace the pricey monthly fee we were stuck with paying other similar solutions (intercom, Tawk.to). Of course, Intercom is made for more complex application needs but that's not the level to be expected from apps like Tawk.to and VOIZEE. There's also an upside. You can still use Intercom's and Tawk.to's basic plan and loop into VOIZEE's VOIP to save on monthly cost. Support does take a day or two to reply, but they are always on top of our support ticket. This is definitely a great buy.
