Hello,
the current server hosting the apt repositories for debian and ubuntu is scheduled for replacement. It hasn't been updated with new packages in a while.
Courtesy of Sipwise, a new build system is under development and should be available in the near future.
Meanwhile, we plan to clone the existing packages to another server and have them available till the new system is up and running.
As all these involve operations requiring DNS change and file transfer, the repositories might be unavailable from time to time.
Many thanks to Jon Bonilla that took care of building the deb packages so far and Inaki Baz Castillo for hosting the afferent repositories.
Note also that all Kamailio packages for latest version are also available via the official repositories from Debian unstable (sid) - thanks to Victor Seva for the work on it. Perhaps testing will get them soon and with the next stable version, should be no longer needed to use our repositories by users of Debian. We plan to keep ours as well.
Cheers, Daniel
