What are the Service Features and Restrictions associated with your Inbound Voice virtual numbers?

The below list shows our virtual number features and restrictions applicable on a per country basis, due to different regulatory conditions pertaining to a specific country.

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 support@nexmo.com to confirm. The list below has 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. You can find international CLI support information in the table below. 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.

 

Pricing for both inbound voice, outbound voice and voice enabled virtual numbers can be found here: https://www.nexmo.com/pricing/
