Ok have a system here running very well for 5 plus years no issues.
The system details is as follow
PBX Firmware: 10.13.66-21
PBX Service Pack: 220.127.116.11
Current Asterisk Version: 11.25.1
its behind on loads of updates
Now the issue arises is time conditions and and system announcement and IVR are need to be added.
the pbx server time is out of sync i believe this is to do with the core module and sysadmin update required, reading through old post.
i have run the updates cycle from the gui and lots of update needed
can anyone recommend the best way without breaking anything and doing extra work?
Just update !
want to stick with v13 for now, or should l upgrade to v14 using tool after all v13 updates installed?
