Hi, I'm trying to place a call to A and then bridge it to B. The problem I'm having right now is that after A answers and while dialing B is being dialed or rining, I want to send A a ringing tone. I don't succeed in doing this. No tone/ringback is being sent to A. Here is what i did using ESL: api originate {ringback=\'%(400,200,400,450);%(400,2200,400,450)\',transfer_ringback=\'%(400,200,400,450);%(400,2200,400,450)\',origination_caller_id_number=4156781020}sofia/gateway/voipms/4152309090 &park() To bridge, I then send the message: sendmsg e9dae14c-e473-466e-9d65-704e36a82e5f call-command: execute execute-app-name: bridge execute-app-arg: {{ringback=\'%(400,200,400,450);%(400,2200,400,450\'},origination_caller_id_number=4152309090 }sofia/gateway/voipms/4156781020 any idea? Max.
