• Twilio requires the customer firewall to allow all of its published signaling and media ranges and ports, and the SIP infrastructure to accept signaling from any of those addresses at all times. in context
• The firewall in front of Asterisk likely needs to admit UDP from Twilio's 168.86.128.0/18 media range to Asterisk's own rtpstart-rtpend range, since Twilio requires its media ranges allowed and Asterisk receives RTP only on that range. inferred in context
• Twilio Elastic SIP Trunking media uses the global range 168.86.128.0/18 with RTP ports 10000 to 60000 at all edge locations. in context
• Twilio Elastic SIP Trunking signaling uses ports 5060 UDP/TCP and 5061 TLS from per-edge /30 ranges, including 54.172.60.0/30 for North America Virginia and 54.244.51.0/30 for North America Oregon. in context
