Polycom IP500 will not dial star or pound

I presume this is a digitmap problem since the phone never sends anything to Asterisk. It just gives a fast-busy when I try to dial for example *69. Asterisk does not show anything in debug mode so I don’t think it ever received anything. Googling finds alot of discussion on this and I have tried several different digitmap settings. Nothing has worked. Is this something in the firmware that this phone just won’t do???

I found I had to delete the digitmap entirely. Are you using a boot server to configure the phone? I found I had to use a boot server to get the changes to commit properly.
