[Ronald Wiplinger]

We try a X-Lite client from remote to connect to my *

I can call X-Lite and X-Lite can call me. However, X-Lite can hear my 
voice, while I cannot hear him.
*CLI> shows
*CLI> (date) NOTICE[4637] rtp.c:317 process_rfc3389: RFC3389 support 
incomplete.  Turn off on client if possible
RFC3389: 5 bytes, level 4 ...

I tried in my sip.conf to change dtmfmode from inband to info and to
