[asterisk-users] DTMF-troubles with Snom

[Jonas Kellens]

Hello,

I have tried several settings.

Normally I set it to rfc 2833 on most phone types 
(Grandstream/YeaLink/Cisco SPA). Works always.

With Snom you have the option : SIP info : on/off/always

Neither of these settings make any difference...


What setting do you have in your Snom phones ??

The problem only occurs when calling with a Snom phone...
If you have 1 IVR-menu, then there's no problem.
But when you add an extra layer (a second IVR-menu), then your first 
input is used for the second IVR also. Strange !


Kind regards,
Jonas.
