Thank you for using Xoxzo, Cloud Telephony Platform.
As we notified on Twitter, our Voice functionality was unavailable from 6AM to 10.31AM (JST) on March 13, 2019.
This is caused by our regular maintenance process and we have applied the possible improvement to future issue prevention.
We are deeply sorry for any inconvenience or loss caused by this issue, for any questions, please contact us at anytime.
Thank you for your continuous support from the team Xoxzo.
