SIP & RTP Traffic Whitelisting
Updated 26 months ago
If you plan to route calls to a SIP URL instead of a standard phone number (e.g., +12123335566@192.168.1.1), it is necessary to whitelist our IP addresses. This ensures that SIP and RTP traffic is properly received by your infrastructure and is not blocked by firewalls or security settings.
Why Whitelisting is Necessary?
When calls are routed to a SIP endpoint, the SIP signaling and RTP media traffic originate from specific IP addresses. If these addresses are not explicitly allowed, your system might reject or block incoming calls, causing connectivity issues.
By adding our IPs to your whitelist, you ensure uninterrupted call delivery and prevent any issues with SIP registration or audio transmission.
