I am looking for a SIP trunking provider and have a few specific requirements.
Offers metered pay per usage service both in and outbound
Does not allow international calling unless requested via ticket. I don’t want the option to turn on international calling from the online portal. (The online portal of one of our VSPs got compromised at one point, international calling turned on and incoming calls forwarded to international toll fraud number. We don’t want that to happen again).
Do you know of any VSPs that offer that?
(Vitelity has that, but we are already using it).
