Only the latest versions are available in the repos. It is not recommended to run an older version as many many bugs are fixed between versions. If you are running into a bug you should open a ticket on jira for that.

If you are in need for rapid pro help to address a bug, email consulting@freeswitch.org and get the pros to help

Hi!

Is there a way to set up different version of FreeSWITCH from repos? 

Means for ex I want to use not 1.6.19, but 1.6.8?

Or compile is the only way?

Regards, Igor
