Twilio's IP addresses for SIP services

You MUST allow ALL of Twilio's following IP address ranges and ports on your firewall for SIP signalling and RTP media traffic. This is important if you have Numbers in different edge locations and for resiliency purposes (e.g. if North America Virginia gateways are down, then North America Oregon gateways will be used). Twilio does not guarantee which edge location the media will egress from, without using the edge parameter since it can depend on which PSTN-SIP Gateway delivers the call to which Twilio edge location.
