SIP Trunking - Regulations Spain (+34)

We would like to inform you that starting  June 7, 2025, it will no longer be possible to terminate outbound calls to Spain if the  Caller ID (CLI) is a  Spanish mobile number.  

This change follows local regulations, which prohibit the use of mobile-format CLIs for  commercial or customer service purposes without the recipient’s explicit consent.  

To help you stay compliant and avoid any service disruptions, we recommend using a  Spanish geographical number as your CLI.
