Looking at ETSI TS 129 414 V7.2.0 (2007-03) Figure 7: UDP/IP Packet with
multiplexed RTP/NbFP payload PDUs without RTP header compression

T=0

Further down in the text:
- RT bit.
The field has two possible values, 0 for indicating full packet and 1 for
indicating compressed packet. Value 0
shall be used for an uncompressed RTP header, as decribed in the present
sub-clause.

Figure 9: UDP/IP Packet with multiplexed RTP/NbFP payload PDUs with RTP header
compression
T=1

So yes if the T bit is one RTP header compression is used.

>How to proceed further to add the code to final build.
???
The code is in TRUNK/HEAD when a new release is made TRUNK is branched of
and released, the upcomming release will be 1.4.0 there may be a development
snapshot (1.3.4) before that. I don't know when 1.4 will be released. Probably
at SharkFest in June as the previous two releases.
Regards
Anders
