Hi!
I'm currently testing H324M video calls with chan_ss7 (incoming). Mostly
it works, but sometimes (20%) the handshake fails - h324m_gw_answer()
does not return (I guess this is H.223 handshake, or is it already H.245?).
If I take a look at the h223_in_....raw files from a good and a bad
attempt, the look similar - no obvious difference - they start with the
same pattern:

Hi Klaus,
This is the h223 data, with empty mux stuffing pdus (no h245 data).
It's always the same or is any h245 message present??

Maybe it tries to make a handhsake several times but fails in the end?
The h223-out file is similar.

Could you print the output in bytes instead of words?
I mean the correct output would be something like:
e1 4d 00 00 e1 4d 00 00 e1 4d 00 00 e1 4d
Does the h245 files display any decoded messages?

In case of successful handshake I see (more or less) random data in the
log file (after the mux stuffing pdus).
In case of unsuccessful call I see the 4de1 0000 e100 004d 0000 4de1
data in the beginning (for a long time). Then I see some other data, like
