[asterisk-users] DTMF not recognized on ISDN with Siemens -not IP- phone

Good day all,

we have following setup: Debian Etch 64, Asterisk SVN-branch-1.4-r66244 
with mISDN 1.1.3 and 2 Digium cards B410P. Our customers calls in the 
office through ISDN lines and then get a possibility to join meetme 
conference. It works well except when customers are using SIEMENS phones 
(not IP): DTMF is not recognized.

Does someone have an idea on what could be the problem with those phones?

Thanks for any help
