Codec pass-through on a transcoder is an odd choice; however, you shouldn’t need a transcoder on analog or TDM ports. They already have a DSP invoked for the conversion to IP. Configure whichever codec you need from the start.

I doubt that your issue with call from/to the FXS ports is related to that you configured a transcoder. Please collect debugs for FXS port troubleshooting and post it here if you require help on this.

thank you I will check I let you know. Thank you very much.

Logs are necessary to have any clue. In the transcoder, add G729 as well, and you can avoid using pass-through as @Jonathan Schulenberg  mentioned.

thank you very much to everybody, the problem was the fxs card itself, after I replace it everything work fine.

the problem was that after finishing setting up trans-coding stop working, probably after reboot the card stop  working.

Thank you.
