3. SIP to BRI

In this section, we introduce how to achieve making outbound calls from 3CX through BRI trunk on TB400.


                                                                                 Figure 10 SIP to BRI

Step 1. Create one outbound route on 3CX.

To make external calls from 3CX through TB400’s BRI trunk, you need to create one outbound route on 3CX.

Click "Add Outbound Rule" on 3CX.

  • Rule Name: Rule for TB400
  • Prefix: 9
  • Call from extension(s): 300-305, allow extension 300,301,302,303,304 and 305 to call out through this outbound rule.
  • Route: TB400
  • Strip: 1

                                                                Figure 11 Outbound Route on 3CX

Step 2. Configure “sip_2_bri” Route on TB400.

Path: Gateway→Routes Settings→Route List

                                                                         Figure 12 IP->Port Route

  • Route Name: give a name for the route, “sip_2_bri”.
  • Call Source: choose the VoIP trunk which is connected to 3CX, “SPS—3CX”.
  • Call Destination: choose the BRI trunk1.

Step 3. Test a call from 3CX.

Now, you can use 3CX phone system’s extension to make external calls through the TB400’s BRI trunk 1. Do not forget to add digit 9 before the called number cause prefix is set to 9 on 3CX outbound route. For example, if you want to call 15880270666, you need to dial 915880270666.

 

4. BRI to SIP

In this section, we configure incoming calls to 3CX through BRI trunk on TB400.

 

                                                                                Figure 13 BRI to SIP

Step 1. Create an inbound route on 3CX.

Click “Add DID/Inbound route” to configure the inbound route on 3CX.

  • Inbound route name: From TB400
  • DID/DDI number/mask: 9999, which is same with the trunk external number.
  • Available ports: TB400
  • Office Hours: Digital Receptionist


                                                   Figure 14 Inbound Route on 3CX Phone System

Step 2. Configure the “bri_2_sip” Route on TB400.

Path: Gateway→Routes Settings→Route List

                                                                  Figure 15 Port to IP Route Page

  • Route Name: give a name for the route, “bri_2_sip”.
  • Call Source: choose BRI trunk1. 
  • Call Destination: choose the VoIP trunk which is connected to 3CX, “ServiceProvider—3CX”.
  • Hotline: set Hotline to 9999, which is the same number with the DID number set on 3CX Inbound route.

Step 3. Test a call.

Dial the BRI trunk1 number 617839972 on your mobile phone, the call will be routed to 3CX’s digital receptionist 800. After hearing the prompt, you can dial any extension number on 3CX Phone System.
