Interconnect Frequently Asked Questions

What is my ASN (Autonomous System Number)?

Ask your network administrator for your company's ASN. If you are using a public ASN, you must own it. If you don't own one, Twilio will issue a private ASN to you in the 65000 range. This will be used to configure dynamic routing using BGP (Border Gateway Protocol), between Twilio and your network.

How do I determine my bandwidth requirements?

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.

How do I send and receive data from my network to Twilio?

Share IP routes for your border devices with your Twilio on-boarding contact. You'll also need to allow traffic from all Twilio IP addresses through your SBC/Firewalls.

What is needed for an IPSec tunnel?

Any router or firewall supporting IPSec VPN should be able to establish a standards based IPSec tunnel to Twilio. You'll receive Twilio's IPSec VPN specification for IPSec Phase I and Phase II. In addition, you'll be able to reference your pre-shared key in Twilio Console.

Where do I find my Twillio Account SID?

Your Twilio Account SID (String Indentifier) can be found by logging into your Twilio Console
