We haven't announced it yet, but we recently rolled out a BETA feature which allows international calling via BYOD to most destinations.

To enable this, login to the BETA control panel at https://beta.voipo.com and go to BETA - International Calling Security. Then set the BYOD toggle to "Enabled" and add the destinations you wish to call with BYOD to your "Whitelist" by following the instructions. You will then be able to call those whitelisted destinations via BYOD. You may have up to 5 countries on your BYOD whitelist at any given time. High-risk and high-fraud destinations remain blocked and cannot be whitelisted.
