To create a Cloud Connect connection, you and Twilio will have to configure our respective network components.
IP Addresses.Your border devices (e.g. IP-PBX, SIP-PRI IAD, Session Border Controller, NAT gateway, etc.) will need to be assigned IPv4 addresses. The addresses have to be public IPs - as opposed to RFC 1918 address ranges - to avoid conflicts with other networks that Twilio platform is peered with. In other words, your IP addresses have to be outside of the following ranges:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Firewall.You will need to add Twilio's IP ranges to the access control list on your firewall (e.g. AWS Network ACL) to allow your and Twilio's platform elements to talk to each other.
IP Ranges.All services accessed over Cloud Connect will come from known Twilio IP ranges. We encourage you to whitelist all of our IP ranges and ports on your firewall.
Cloud Connect Connection.Twilio will provision bandwidth for your connections at Twilio Interconnect locations selected by you. See connection bandwidth and location options listed below.
- 10-Mbps connection
- 100-Mbps connection
- 500-Mbps connection (available in London & Singapore)
- 1-Gbps connection
- AWS US East (Virginia) via Interconnect Exchange in Ashburn, Virginia
- AWS US West (Oregon) via Interconnect Exchange in San Jose, California
- AWS EU (Ireland) via Interconnect Exchange in London, United Kingdom
- AWS Asia Pacific (Singapore) via Interconnect Exchange in Singapore
|Connection bandwidth and location requirements||so that Twilio can provision adequate bandwidth for your needs||to estimate bandwidth, convert your maximum number of concurrent calls to required throughput in Mbps. Many of our customers found the following ratio helpful: 1 Mbps of bandwidth is roughly equal to 10 concurrent G.711 codec calls.|
|Your IP addresses||so that Twilio can allow traffic from your network||share IP addresses for your border devices with your Twilio onboarding contact|
|Twilio’s IP ranges||to allow traffic from Twilio to your network||ask your network administrator to permit traffic from Twilio's addresses/ports|
|Twilio account SID||so that Twilio can allow traffic to/from this account to go over the Cloud Connect connection; also, monthly Cloud Connect charges will be applied to this account||look your Accound SID up in Console Dashboard|
Your onboarding contact will let you know when provisioning is complete.
