Summary:                    [patch] Some issues with New SDP handling code and
T.38
Description: 
- Connection information defined at media level are not read. If SDP don't
define a (c=) at session level, process_sdp() fail with "Insufficient
information in SDP (c=)...". The patch add processing of (c=) defined at
media level for image too.

- As process_sdp() now use a dedicated "isin" sockaddr_in,
sin.sin_addr.s_addr stay null in case of T38 re-invite. This force to hold
the channel. If MusicOnHold is present, generator is setup on the channel.
This result in dropping all udptl frames... The patch add a check on isin
to avoid unwanted Hold state.
