ScopTEL implements an Asterisk version switcher in our Packages Manager.
The version switcher easily toggles between Asterisk versions 1.4, 1.8 and 11
Each Asterisk version may have its place in the real world scenarios even though Asterisk 1.4 is discontinued.
Version 1.8 added great new features in Connected Party updates, CCNB, SRTP
Version 11 finally gives Asterisk T.38 gateway support.
Now you can choose which Asterisk version to deploy and quickly switch between versions to choose which version is best for you.Module 4 - ScopTEL - Version Switcher for Telephony Server
