[Freeswitch-users] FS as callback server pass through ring back tone form B leg to A Leg

Hi There we have FS as a Callback server right now we play our own RB tone $con->execute("set", "transfer_ringback \%(400,200,400,450);\%(400,2000,400,450)")right after a short welcome message. But that's not really how we like to have it. instead of our own RB tone we like to pass through the B-leg RB Tone to the A-leg. I know this is a question asked before and we tried to read through the forum. But all suggestions we found and tried did not work. WE can not make the Box passing through the RB tone from the b-leg Any suggestion or how to is highly appreciated. Hope to get some good answers -- With best regards Karl Theo Hofer M: +46 7030 22178 E: karl-theo_hofer@inteli-sim.com
