Here is the log file with the dropped and silent call again after applying the changes you suggested:

I have the -Dt option added, I'm not sure why it's not working.  Here is the full command I am running via command prompt:
yate-console.exe -Dt -l log.txt -t

Hi,
Sorry to be so late, I didn't noticed the new page and didn't saw your post!

The log is showing the call being terminated by yate due to OK timeout.
The jingle channel is responded, yate sends OK on incoming sip and retransmits it.
Finally the call is dropped because OK is not confirmed.

This may indicate network errors.
The caller may be behind a NAT.
