This page lists the Bring Your Own Carrier (BYOC) IP addresses, by carrier, that you can use in your Access Control List (ACL). Google recommends using all appropriate IP ranges to help avoid call failures.
Media IPs
Media IP addresses are for real-time transmission of audio data during a SIP session. After a call is established using signaling, the voice streams flow between these media IP addresses. Implementing the correct media IP configuration is critical for clear and uninterrupted media exchange with your carrier.

Signaling IPs
Signaling IP addresses are for controlling and managing SIP sessions. They transmit messages that initiate, modify, and terminate sessions. Proper configuration of signaling IPs is essential for CCAI Platform to correctly communicate call control information with your carrier.
