Trying to pack all the UDP (SIP + RTP ) into a TCP packet before sending

Hi guys,
I am working on pjsip on symbian . I am trying to pack all the SIP and RTP
data generated by pjsip into a tcp packet and send it to a single port proxy
server .
In order to do that which file should I be modifying ? I am looking at  the
in the pjlib/pj/src/sock_symbian.cpp and looks like that is where the msgs
get sent .
So is it enough if I modify this file? or should I be  considering other
factors here as well ?

Don't expect a TCP transport to be working for media on high latency
networks such as EDGE or GPRS, or even on networks with packet loss
(just 0.5% BER will kill the flow) where TCP congestion will occur and
block the audio flow.
