If you’re using Twilio Elastic SIP Trunking to connect your IP-based communications infrastructure to the PSTN, then you’ll be happy to hear that starting today, you can specify the geographic region that Twilio will use to send the originating SIP traffic.
By default, Twilio uses the region where the incoming PSTN call comes in from. Starting today, to specify the region you want Twilio to use to send the originating SIP request towards your communications infrastructure, simply include the optional region parameter in your origination SIP URI. This can lead to improved voice quality as traffic will not automatically traverse to the region of the incoming PSTN and, moving forward, calls will be directed over the Twilio Super Network—to the specified region—instead of the public internet.
For example, by including region=ie1 in your origination SIP URI, Twilio will send the SIP request from the Europe Ireland region. View full list of available regions.
To select the region you want Twilio to send origination traffic from:
- Update your IP address list with the region you’d like to use for SIP signaling and RTP media traffic.
- Include the appropriate region parameter in your origination SIP URI.
Twilio Elastic SIP Trunking offers instant provisioning with contract-free and transparent pricing so enterprises can deploy SIP trunking in minutes and at a fraction of the cost previously possible. Twilio uses the power of the cloud to deliver a highly resilient global architecture, with no capacity limits.
We can’t wait to see what you build!
