[asterisk-users] Ring back when free?

[Dean Collins]

Hey Tony, in the pbx space that feature is called "camp on"

I have no idea why - just thought I'd let you know.

> 
> 1. A calls B. B is engaged (busy).
> 2. A hears "The number you called is busy. To use ringback, press 5"
> 3. A presses 5, and hears "Your ringback request has been accepted".
> 4. A hangs up.
> 5. Later, B hangs up. The system then calls A (if A is now busy, it
>    waits until A is clear again).
> 6. If/when A answers, the system calls B on A's behalf and A hears
ringing.

> Any implementation has to cater for the fact that when B is busy, he
> could be either the calling or the called party on his current call.
> If he is the calling party, he will execute 'h' when he clears, but
> if he is the called party, he won't be in the dialplan to execute 'h',
> so we need some other way to invoke the ringback (step 5).
