--------------------------------------------

btw, if I use SIP I see dtmf in debug:

> Hello!
> I migrated our centos6 and asterisk 13 installation to oracle linux 8 and asterisk installation several days ago using the same configuration as before.
> Yesterday user complained that he can't reach conference room on another side's cisco cucm and to enter this room he have to enter dtmf code, which is not recognized.
> This is how our systems are connected:
> PBX<--isdn pri-->asterisk<--h323-->ast-neftisa<---h323-->cucm
> I got traffic dump on ast-neftisa and I see no dtmf code passed to cucm address 10.77.6.21, I'll upload traffic dump.
> But if I set asterisk call flow to sip between asterisk, then I see dtmf in dump
> and everything works as expected
> PBX<--isdn pri-->asterisk<--sip-->ast-neftisa<---h323-->cucm
> Unfortunately, I have no idea what is changed between asterisk 13 and 18, but looks like bug in chan_oo323 for me..
