G723.1 codec Audio problem in pjsip

No, no

my meaning is, what if i want to implement for example AMR-NB  .

Other than the codec interface in pjsip, it's required also to implement 
an RTP profile specific for such codec?

Like http://www.rfc-editor.org/rfc/rfc4867.txt ( 
http://www.cs.columbia.edu/~hgs/rtp/ )
