NAT

In cloud-based PBX deployments, Network Address Translation (NAT) is a key factor in ensuring seamless communication between private internal networks and external public networks. As most enterprise environments operate behind firewalls and NAT devices, effective NAT handling is essential for maintaining reliable signaling and uninterrupted media flow in VoIP and WebRTC sessions. Telsip Cloud PBX implements NAT traversal mechanisms to preserve call quality and ensure consistent connectivity, even when endpoints are situated behind routers or firewalls.
