We are likely (very likely) going to deprecate the usage of AgentCallbackLogin in the Asterisk 1.4 release. With the proper dialplan logic, the entire function it provides can be done without the use of proxy channels and additional locking. When the deprecation occurs, we will also include a file in the doc/ directory showing an example dialplan of how to replicate the functionality.

We (Digium) just converted our PBX from using chan_agent callback mode to using dynamic queue members via dialplan logic and it solved a number of problems we were having, with no loss of functionality. This mirrors the experiences of other customers we have helped (through our support department) do the same thing. Given that, it seems to be a significant waste of resources to try to fix the locking problems caused by chan_agent when it provides no additional value.
