Problems with dtmf touch tone menusand Polycom 500 IP phones

Hi,

we use the IP 500 with 1.6.x firmware together with Asterisk 1.2.7.1.

At momentan we are no more able to navigate through different remote (not the local asterisk menus) touch tone menus.

We played around with the dtmfmode setting without any luck.

Can anyone help with this problem.

Kind regards,
Bernd

you say ‘no more able’ - what did you change, because if it was working before and you changed something, odds are that the change is the cause.

if you didn’t change anything, you’ll have to post a bit more info.

I do not know since when it does not working anymore. But I know that it worked.

Here I post my sip.conf part and the extension.conf part, maybe this is enough info.
