Meetme DTMF issue?

Hi.
I configured 2 functions: F1#F2 in features.conf
In the normal dialplans the functions works perfectly, but NOT work in the Meetme, why?

Check, In the meetme dialplan look like this;


…Set(__DYNAMIC_FEATURES=F1#F2)
…SIPDtmfMode(inband)
…Meetme(2301,qF)

But I can’t execute the Features, I press a digits and I only listen the digits but don’t execute my functions F1 and F2. How can I solve this?
