I have never used inband. I always used rfc2833.
 
This problem is seen even if you are using dtmf=rfc2833. 
 
the line progressinband=no,  fixes that.

	Are you using inband DTMF? There are other options but I don't
know much 

	about the polycom phones. I have noticed that sometimes when
accessing 

	voicemail, it will 'miss' some dtmf tones if they are too short.
This 

	doesn't explain the number changing, unless your dial plan is
putting in 

	the leading zero.


If you are using a version of CVS HEAD from April 2005 or later, you
should definitely use dtmf=rfc2833 rather than dtmf=inband.  In fact,
just use rfc2833 - it works with all versions of asterisk that I've
tested, but inband only works with certain versions.

Also, you may want to check the digit map (the pattern recognition when
you dial).  It is in sip.cfg.  I know that by default it treats numbers
that start in "11" specially, but it shouldn't really transpose numbers.
That's weird.
