I have my connection as below, diax(IAX) ---> (IAX) * (IAX) ------> IAX(*) ---> PSTN In the middle tier of asterisk, it if not completely forwarding the stream and it consumes the system bandwidth. I DONT have settings like notransfer=yes Can you please help me how can I transfer the call to the next asterisk without consuming the bandwidth and just monitoring the call alone. I would like to know when the call is started and when the call is ended from the iaxclient with the dest. asterisk. Kannaiyan
