Description:On a zap channel, if you have an established call and then dial Recall you obviously get dial-tone. Now if, within one second of having done that, you go on-hook, the party on hold immediately gets busy-tone.

(If you wait for more than a second before going on-hook, your phone rings, and when you pick it up, you're re-connected to the origial party on hold - ie the expected behavour.)

****** ADDITIONAL INFORMATION ******

It may or may not be related, but in South Africa (za) the timing of a Recall is 100ms, so the bug may not be reproducible for countries where * has to wait for up to 1250ms for a recall.

This is not a bug.  This is actually the intended behavior because some hook switches are noisy and create a hook flash before going on hook.  Without that behavior, it would cause the line to ring back with a "phantom ring".
