Odd warnings in the CLI output

I am running Asterisk 1.2.21.1 on Gentoo Linux

I keep getting this warning spammed on the CLI.

WARNING[31068]: file.c:1045 ast_waitstream: Unexpected control subclass ‘2’

I have been trying to google this, search these forums for what this might indicate. Either I am blind, or there just isn’t anything. Does anyone have a clue as to what this might mean?

I am running two TE410P Cards, with a mix of ISDN and CAS T-1 trunks, with sip users on the IP side. Pretty basic stuff, this is the first time I have seen this.

Thanks in advance for any help.

If I remember correctly, ast_waitsteam is to allow an interruption of a file playback based on a DTMF input. I am looking at the code now and it would seem that you are getting an invalid break because asterisk is recognizing noise as a break character, but the DTMF “2” in your case doesn’t do anything. So it is doing a case-break default. I would check your circuit for noise.
