It actually was fairly trivial once I knew that function is all I
really needed,aside from changing how the "F" flag is declared at the
top of app_meetme and changing AST_FRAME_DTMF_BEGIN to AST_FRAME_DTMF
it was pretty much a direct copy from the 1.4 SVN trunk code.

I have made a patch, and have tried this on 2 systems running 1.2.23
and 1.2_SVN with both of them passing through DTMF from SIP to Zap and
Zap to SIP just as I need. I am planning on trying this in production
tomorrow to see how it does.

Here's the patch if you are interested:

Thank you very much for your help on this,
