Here are the rules of the game:
|
|
1. The chan and peer channel pointers will not change
|
|
during the life of the bridge.
|
|
2. But, in transfers, the channel names will change.
|
|
between the time the bridge is started, and the
|
|
time the channel ends.
|
|
Usually, when a channel changes names, it will
|
|
also change CDR pointers.
|
|
3. Usually, only one of the two channels (chan or peer)
|
|
will change names.
|
|
4. Usually, if a channel changes names during a bridge,
|
|
it is because of a transfer. Usually, in these situations,
|
|
it is normal to see 2 bridges running simultaneously, and
|
|
it is not unusual to see the two channels that change
|
|
swapped between bridges.
|
|
5. After a bridge occurs, we have 2 or 3 channels' CDRs
|
|
to attend to; if the chan or peer changed names,
|
|
we have the before and after attached CDR's.
