[Freeswitch-dev] VoIP Security

To be clear, I'm not advocating carrying around older libraries, but I am strongly advocating using a distro that is not based on package versions from 5+ years ago or a distro that is no longer actively maintained if you want any sense of stability or security.  There are many fixes that come in the form of new API's that simply are not possible to backport, or major fixes that do not meet the requirements for backport in other ways.  Using centos5 for example will become much much more difficult for the user in future freeswitch 1.4 releases because freeswitch simply needs capabilities added to libraries within the last 5 years, that are just not readily available on centos5.  This will require users to manually install more recent versions of libraries to meet dependency requirements, which of course negates all of the reasons you use a distro in the first place.
