ExtensionStatus with Zap/1r1

hi !

I need some help (with my very bad english).
If I call an FXS extension with Zap/1, in the manager, I get an ExtensionStatus Event.

[code]>>>>-----------<<<<
Event: ExtensionStatus
Privilege: call,all
Exten: 101
Context: ext-local
Status: 8

-----------<<<<
Event: ExtensionStatus
Privilege: call,all
Exten: 101
Context: ext-local
Status: 0[/code]

If I call the same extension with Zap/1r1 (to have CID on my french DECT phone), I don’t get any ExtensionStatus Event.

I can’t find what I can try to get it again.
Any help appreciated.
