<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Prior to this patch, local channel names would look like this:
Local/exten@context-####;%
where #### is a four digit hexadecimal number picked completely at random and % is which index of the local channel created as part of that local channel creation event that channel belongs to.
This changes that to:
Local/exten@context-########;%
Where ######## is an eight digit heaxedecimal number picked based on a sequential order from when the channel requested its number. The value is incremented atomically so that the same number can't be grabbed by two parallel threads. This should make overlapping channel names a non-issue as long as we aren't keeping billions of local channels alive at the same time.</pre>

It just wraps back around. It appears to work identical to how it does with SIP as far as the identifying value is concerned.</pre>
