Configuring your Twilio Trunk With Vodia PBX

Published on:

October 3, 2019

To configure your Twilio trunk with the Vodia PBX, start by logging into Twilio and creating a trunk under Elastic SIP Trunking, where you set the termination SIP URI and localized options based on your location. Establish an authentication IP access control list by adding your Vodia PBX IP address, then create a credential list with your username and password, then create an origination SIP URI pointing to your PBX. After purchasing a Twilio number for inbound calls, complete the trunk setup in Vodia by entering all relevant SIP details and configurations; this ensures accurate registration and routing settings to facilitate efficient calling operations.

Log in to your Twilio account to start.

Termination URI

  1. Under Elastic SIP trunking, create a trunk name under general to name your trunk.
  2. Next is Termination, create a termination SIP URI,
  3. Name the Termination SIP URI (for example, (mycompany).pstn.twilio.com); this SIP URI will be used for the outbound proxy of the trunk.

Twilio also has localized Termination URI. You can use this based on your location, so with your newly-created SIP URI you can also use mycompany .pstn.us1.twilio.com, etc.

  • {example}.pstn.us1.twilio.com (North America Virginia)
  • {example}.pstn.us2.twilio.com (North America Oregon)
  • {example}.pstn.ie1.twilio.com (Europe Ireland)
  • {example}.pstn.de1.twilio.com (Europe Frankfurt)
  • {example}.pstn.sg1.twilio.com (Asia Pacific Singapore)
  • {example}.pstn.jp1.twilio.com (Asia Pacific Tokyo)
  • {example}.pstn.br1.twilio.com (South America São Paulo)
  • {example}.pstn.au1.twilio.com (Asia Pacific Sydney)

Authentication IP access control List

Authentication is used to authenticate the termination SIP URI IP address or FQDN

  • Click on the +button, friendly name: My business name
  • Add an IP address range: Your PBX IP address
  • Friendly name: VodiaPBX and save

Credential list is used authenticate the user and password of the SIP URI

  • Friendly name: mycompany.com
  • User name: The user who will be passed when authenticating the SIP request
  • Password: The password used by the user to the authenticate the SIP request

Origination

Here you will create the origination URI.

  • Origination SIP URI: sip.mypbxbuisnessname.com can also be an IP address.

This will be used to send traffic to the PBX, so if you don’t have a FQDN you can always use your external IP address:

  • Click on the Plus button and create the (Origination SIP URI) could be IP address or FQDN

Number

Purchase a number from Twilio to get inbound and CID working.

Once you have purchased your number you can point the number to your SIP trunk.
