Hello. Today we are going to look at how to set up SIP trunk and number. For this demo we will use Twilio as SIP trunk. In Consent app, let's go to Sip trunk menu. Click Create button. Let's name this trunk as Twilio. We need to fill in configurations like SIP proxy address of Twilio which will be used to initiate outbound calls. We also need to whitelist Twilio's IP address from where we will receive inbound calls. Let's log into Twilio Console. Click on Trunks menu by expanding Elastic SIP Trunking and Manage menu. If you do not see Elastic SIP Trunking inside menu, you may need to pin it by clicking on Explore Products menu. In the trunk space page you will see existing trunks if you already have one. For this demo we will create new trunk and give it a name. Demo Let's go to Termination menu. This is used to configure outbound calls. Let's add a unique sub domain for termination SIP URL. Twilio needs some way to authenticate outbound calls signals coming from consent. We can add consent servers IP address to be whitelisted. Let's copy comments IP address from Sprunk creation page. Second way to authenticate is by creating username and password and copying the same in consent script drunk page by enabling outbound credentials. For our case let's use IP whitelisting for authentication. Let's remove credentials in consent and Twilio setting page and select IP address we previously configured and hit save. Let's add termination, say purl in constant trunk setting page. These steps will enable us to make outbound calls. Now let's add configuration for inbound calls. Let's go to origination menu and add consent SIP servers domain name as origination. Add zip prefix. Copy constant server address from SIP trunk menu and paste it into your page. Now when inbound call is received, Twilio will forward it to consent. Twilio needs to authenticate if inbound call signals are coming from genuine to your server. For that we need to whitelist Twilio's IP address in Command server. Let's get Twilio's IP address from Twilio's documentation and paste it in Consent SIP trunk page and click Create button. Now it's time to configure phone number. Let's go to Active Numbers page by expanding phone numbers and Manage menu. Already purchased numbers will be shown here. Click by a number button to purchase new number. We will use existing number for our demo. Currently this number is configured to work with webhook. We need to change it to work with SIP trunk. Click the number. Change configure with drop down. Two sip trunk. In the next dropdown choose SIP trunk which you created in previous steps. In our case SIP trunk is already selected. Hit save. Let's configure this number in consent. Go to numbers page, click add button, fill the form. I am adding sales as a name to identify the number. Type Twilio number in East 164 format with plus one prefix. Select previously created SIP trunk from drop down. You can configure regex pattern to restrict the outbound calls. Flow diagram is used to configure what happens when Comm Center receives inbound calls. Let's add dial block. Edit dial block to add current users username. In this case it is called user one. Click Save. Click on Start and click on dial block to create directed edge between these two blocks. With this configuration, inbound calls will be forwarded to configured user. Save the configuration. Let's go back to origination menu of SIP trunk. Click on Make a Test Call button to test. If setup is correct, we should receive a call. We have successfully configured consent to work with Twilio. You can follow similar steps to connect Coms and with other symptom providers. Thank you.
