Hi Moises Silva,

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

SS7 tapping is not supported, it would involve some significant work to make it work, but is doable. Drop me a line if you’re interested.

I have a pure-signaling SS7 solution here: https://github.com/moises-silva/sng_ss7mon

In order to do passive monitoring of ss7 lines is needed a proper patch of chan_dahdi and libss7 in the dahdi tap version 1.6.2?
Can you tell me some hints regarding a ss7 tapping solution using asterisk?

Thanks.

Not really.

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.
