[asterisk-users] Want to know Frequency and lenght of Frame

[sanjay.rajdev at featherstoneinformatics.com]

I am planning to write a module to find if a Special Information was detected or not.

Can anyone please help me to figure out the below fields?
1. The Frequency of a frame 
2. Length of frame in milliseconds 

Thanks in advance.

Regards,
Sanjay.
