Hello!

Just installed asterisk 13.2.0 and see many such messages in log, I see 
them in console during calls, really something like this:

This is call from H323, as I know avaya ,  chan_ooh323 from my side to  
another asterisk SIP chan_sip on both sides.

Just because everything work OK, I , definitely, can comment out this 
error message, but...
Could you give me any idea why this error can appear?

Thank you!
