[pjsip] via header and TLS on a Freeswitch PBX

Thank you, 

Do you have an idea when the 1.x series from the trunk will reach the
1.0.x series ? We are shipping our software with the 1.0.3 but might
switch to the trunk momentarily because of that. 

Also, we are in touch with Francois Marier <francois at debian.org> so that
we could integrate the Debian/ubuntu repos. Packaging PJSIP is a
pre-condition and the 1.0.x is obviously going to be chosen over the
version from the trunk. This is expected to happen in the next few
weeks.
