[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 -- Daniel

It defaults to 100 and I had an issue with one site where if people called in on a mobile phone it was fine, but if they called in from an analogue land-line it wouldn't detect tones until I dropped it to 50.

The current Digium BRI cards need the phones to send DTMF over as SIP-INFO. Not sure why, but googling should help. (I think this is even covered on the Digium site) PaulH On Wed, 2007-11-28 at 09:47 +0100, Administrator TOOTAI wrote:> 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.
