Hello Tzafrir,
I made the tests you requested and this is the result:
judging by the ztmonitor visual interface there is no audio at all in
the RX channel, while there (should) be on the TX one. The same result
is with or without the -p option.

But no audio was heard at all (in bot channels) on the phone.

Is there something else I can do to better diagnosticate the problem?

Thanks,
Alex
