I have an asterisk 16 version installed and connected with telecom operators SIP Trunk.
I have heard about the take-back and transfer where I can transfer my A party call to B Part and make my asterisk channel free. Normally if I transfer the call to A Party to B party still my 2 Channel will be used in the asterisk server. What I want to achieve is to transfer the call from my asterisk box and made the channels free in my asterisk server.
Can someone help on this.
