Complicated answer, that one.

In this case, when the agent answers the call, app_dial invokes a copy of ast_bridge_call() to bridge the Local,2 channel with the SIP channel it created. It then sends 'answer' to the Local,1 channel, which causes app_queue to invoke a copy of ast_bridge_call() on the original channel and the Local,1 channel. This then causes chan_local to masquerate the SIP channel on top of the Local,1 channel, and the Local,2 channel is destroyed. When this occurs, the ast_bridge_call() that app_dial invoked is exited, but the channel no longer exists, so dialplan execution cannot continue.

If you want this to work, you'll have use the '/n' option for chan_local, as in:

AddQueueMember(Local/99 at AgentQ/n,...)
