What is Nexmo's inbound voice channel capacity?

The inbound capacity of Voice virtual numbers depends on the country. By default we provide 50 channel capacity per number for the majority of countries, but there are a few with exceptional restrictions. If you need to a higher inbound capacity for a number, we could likely accommodate. Please contact to confirm. The lists here (Voice only Numbers), here (SMS+Voice Numbers), and here (Toll-free Numbers) have full feature and restriction details for voice-enabled virtual numbers by country.

Important notes

CLI (Caller Line Identity/Caller ID) for in-country originating calls is regularly tested and is confirmed to be supported for all of our virtual numbers. Generally CLI will be transferred only if the originator or caller's carrier passes the CLI transparently to our network. If the originating carrier hides CLI it cannot be transferred.
