Hello all,

I just want to ask a quick question regarding a forking scenario.

INVITE------------>|
                   |------>INVITE phone (1)
                   |------>INVITE phone (2)
                   |<------180 Ringing phone (1)
<---180 Ringing(1)-|
                   |<------180 Ringing phone (2)
<---180 Ringing(2)-|
                   |
a little later..
                   |<------480 response from phone 1
<---480 (1)--------|
----ACK (1)------->|

Imagine the INVITE forking to two endpoints and both return a
"180 Ringing".

Let's now say that, after a while, one of the endpoints return
a "480 Temporarily Unavailable" message.

So, my understanding is this:
This will stop the call on one of the forks but, on the
other fork, the phone will keep ringing.

Is my understanding correct?

Many thanks in advance,

Attila
