I need to make next callback. 1. Incoming call occurs through sip-trunk-1 from Remote User 2. Elastix catches his CID and hangs up 3. Elastix waits N sec 4. Elastix calls Remote User using CID through sip-trunk-2 5. Remote User picks up call and dials some Number by tones 6. Elastix calls Number through sip-trunk-1 and connects it to Remote User Is it posible through web interface or I need to edit some conf files and scripts? And how it can be done?
