Hi,
 
I am an infant in the field of Telecom. Please excuse if the query is
too basic.
 
I know T.38 is a protocol for sending FAX over Internet Protocol. 
But i wanted to know what codec it uses for encoding the data(i.e.
whether T.38 itself is a codec).
Is it necessary to use any codec (eg. PCMA, PCMU, G729) for encoding the
data when i want to send FAX from one endpoint to another?
 
regards,
san
