Hint on multiple devices

Hi, I need help please.
How can I make 1 hint “watch” 3 lines?
As when any of the 3 lines is on the phone, it will show me.

Thank you

List all the devices, separated by &s. I hope it applies the correct logic for busy and inuse.

I didn’t understand

I have this

[hint]
exten => 900,hint,IAX2/sinet
exten => 9381,hint,IAX2/sinet
exten => 953,hint,IAX2/sinet

If it is possible I want to have the hint on number 951
Please wright me how to do druhého it

Thank you

You only have one endpoint there!

Are you talking about destinations reachable by sending routing digits to an intermediate point. In that case, I don’t believe Asterisk can see beyond the connection to the intermediate node.

What I meant is that, if you have three directly addressable endpoints, say IAX2/a, IAX2/b, and IAX2/c, you should be able to use:

exten => 951,hint,IAX2/a&IAX2/b&IAX2/c

Oh, I forgot… Sorry… It’s like this:

[hint]
exten => 900,hint,IAX2/sinet
exten => 951,hint,IAX2/oxo-pbx
exten => 9381,hint,IAX2/mstx-Ba

This means: ?
exten => 951,hint,IAX2/sinet&IAX2/oxo-pbx&IAX2/mstx-Ba
