SIP Peering lets you connect an IP-PBX directly to SIPcity’s public SIP proxy (27.111.12.66) using a static IP address. This differs from registration, which uses an authenticated username and password.
Once SIP Peering is enabled, SIPcity whitelists your WAN IP and blocks all other IPs from accessing the service. For additional security, configure a firewall rule to restrict SIP port access to our public IP range 27.111.12.0/24.
