If you do this in ast_rtp_write(), you'll be looking up and parsing the 
value of this variable for every single packet that is sent to the peer. 
Is that actually necessary?

More likely you could look it up one time in sip_call() or something 
similar, and then store the value in the rtp internal structure for 
future use during the call.
