Icon to turn video off is hard to workout which one it is. Overall it’s bad. Lasted 5 mins on my phone. ### 1/5 — Absolute garbage. *2019-12-19, version 9.0.2.0* Absolute garbage, should have read the reviews. Client logs out on its own after about 10 min. Bad connection, no support. Useless. ### 3/5 — Good until stoped working *2016-12-15, version 4.0.4.6* Overall is good some minor glitches with the UI does not scale properly. And recently started crashing when trying to make a call. So impossible to make a call. ### 1/5 — SIP agent restricted *2016-09-26, version 4.0.4.0* My VoIP provider restricted use of this client. ### 2/5 — Call *2015-01-10* I did not get replied back . What the service you giving ### 3/5 — Okay, but not great. *2014-10-17* App is okay, not great. Would be better if you could receive calls from multiple SIP accounts. Also the line feature is ambiguous, not sure how to use it. Save your money. ## Frequently asked questions about VaxPhone ### What is VaxPhone used for?
