I have rebuild libpre, zaptel, and asterisk as usual, and installed (version 1.2.0_beta1 from ftp.digium.com) all new files in my system. I have managed to migrate all conf files cheking each mine and each new sample.
After all, I got a fully functional PBX exept all incoming sound from ISDN was absolutely noisy (but the sound sent to the caller was perfect).
I was using a “Diva 2.02 PCI S/T” with ISDN4Linux, and chan_modem_i4l.
After this unsuccesfull try, I rebuild version 1.0.9 and all works grate (as long as I have tried).
Does anyone know why would I have this problem?
Thanks for your time
