If we fix this, we should have named pickup groups that can have other attributes as well in the future, possibly using ast_objects. Using bitmaps and numeric matching was something useful when CPUs had less power than today, when people have dual core in their pockets. This patch is just a short-term patch, not the solution to the problem for me.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Personally I believe that the old callgroup/pickupgroup system should be replaced completely by Pickup(@PICKUPMARK) and only remain for backwards compatibility for a while.
However, you can have multiple callgroups while one channel can only be assigned to one PICKUPMARK (fortunately Pickup handles 123@PICKUPMARK&134&PICKUPMARK). If it was possible to add multiple PICKUPMARKs somehow, it would be possible to deprecate callgroups/pickupgroups with no loss of functionality. If we can find someone to do the coding, I can probably find a sponsor for the work :)
In the meantime it is difficult to argue against code which is already written. The only objection I have is why not use long or long long? int is 32-bit on all the 64-bit systems supported by Asterisk right now, whereas long is 64-bit on those except on Windows. Long long is 64-bit everywhere even on Windows, at the cost of software emulation on 32-bit.

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The suggested fix on basis of named groups without a fixed limit is going to make it into Asterisk 11 now.
Please see https://reviewboard.asterisk.org/r/2043 'Extended maximum number of pickupgroups (callgroup/pickupgroup)'</pre>

<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;">Currently the number of callgroups/pickupgroups is limited to 63, because the variable type that holds the group bits is a long long.
Here's a patch that extends this variable to an arbitrary-length (determined at compile time) int array. It currently sets the max number of groups to 1024.
It implements this for all channels, but I only tested SIP and DAHDI.
Some people might object to implementing this as an array of ints, because it introduces a loop. But I think call pickups are not done often enough for this to become a problem.

I ported it over to 1.6.2 and tested it there. The patch uploaded here is against trunk which is currently being tested by a colleague of mine, but they are all basically the same patch. </pre>
