From the FreePBX menu => Outbound Routes, where it is needed to write the following: -7- Route Name must be a descriptive name of route Dial Patterns example of extension number Trunk Sequence this is the trunk that we configured As a result: For PBX 1: For PBX 2: [200-dial2xx] [100-dial1xx] [2xx] [1xx] [IAX2/200-peer] [IAX2/100-peer] The last step is to set some users or Extensions. All in all we need 25 users for PBX1 and 25 for PBX2. We will describe the creation of 2 users as the configuration of rest is absolutely the same. From FreePBX menu => Extensions where from Add an Extension menu we select «Generic SIP Device». On page which comes after that the following parameters were required:
