Block Outgoing calls -

hi ryanle,

please check with zoom support.  the following suggestions may work for you.

do not assign calling plans to users only permitted to make internal cals.

To restrict international calling to certain countries, please see

Enabling or disabling international calling - Zoom Support

Do not turn on International calling outside of calling plan.

Only assign domestic calling plans to users that you permit to make outgoing domestic calls. 

those users permitted to make international calls could be assigned international calling plans.
