[SR-Users] no event received for call disconnection

Mon Nov 6 11:34:00 CET 2017

Hello,

only master branch got the patches, you have to install from:

http://deb.kamailio.org/kamailiodev-nightly

See the wiki for more about available debian/ubuntu repos:

  -
https://www.kamailio.org/wiki/packages/debs#kamailio_development_master_branch

If all works fine, then I will backport to 5.0. I didn't want to break
stable branch 5.0 without any testing, as I don't have a testbed to
replicate your use case.

Cheers,
Daniel
