When using module admin to upgrade, AST cannot be upgraded because of the following:
Asterisk REST Interface Users cannot be upgraded:
Requires engine asterisk (>= 12), you have: asterisk 11.14.1
The problem with running asterisk-version-switch to 12 or 13 is BLF will cease to function as it does in 11 (currently at 11.14.1). By that I refer to the display on a SIP phone that has 1 or more BLF lines.
On a BLF monitored line under 11.14.1 the CallerID will be displayed on the phones screen. This is a very useful feature for people who pick up calls intended for another endpoint but don’t want the call to go to VM or some other destination.
When asterisk-version-switch is run and asterisk is upgraded to 12 or 13 what is seen on the screen of the phone is the extension number being monitored. Nothing else.
I am not certain if this problem has something to do with the script ‘asterisk-version-switch’ or with asterisk itself.
Perhaps someone can shed some light on this issue.
