I have configured PRI passive call recording using asterisk 1.6.2 tapping with sangoma A102D card.
the problem is, whenever hearing some of the asterisk recorded inbound calls audio the called (agent) party voice have silent. However, the Caller (customer) party voice can hear clearly.
After analysis the asterisk log, I have found the issue in only calls have recorded in Dadhi channel 1 (DADHI/1-1) and remaining channel calls were good. As per sangoma tech team instruction, I have captured audio from DADHI/1-1 channel using “dahdi_monitor 1 -r output_rx.raw -t output_tx.raw” command. As my observation, i can hear the called party (agent) voice in output_rx.wav audio but i can not hear same called party voice in asterisk recorded audio.
Please give me solution

]]>I am not maintaining anymore this solution on Asterisk. You should try FreeSWITCH, the solution for tapping there is cleaner because it does not require patching, which is easier to maintain for me.
I will be making a blog post about this later on.
