Hello all,
Finally, I had to downgrade the asterisk/zaptel and use chan_ss7. The linkset is up and I can hear audio in both directions.
I think there was something wrong in the libss7-1.0 with the asterisk-trunk because the link had those symptoms:
- Originating a call from CLI with Originate command:
- application SendDTMF works, and with dahdi_monitor I could see TX and RX traffic (when I talk).
- application Playback doesn't work, and with dahdi_monitor I could not see TX traffic (0 bytes). I could see RX traffic (when I talk).
- I use Monitor to record the call, and the file-in (RX) is empty, the file-out (TX) has the audio of the played prompt.
I hope it could be helpful for someone.
Regards,
Daniel
