Agent announcement patches available and stable?

Hi,

I have implemented a tech support calling queue for my company that works almost exactly as we want it to.

The one problem is that our support techs often rely on their cell phones to retrieve the calls. It is rather bad form for them to hear silence when they answer. I know, all they have to do is press the # key. But this is not a good solution.

I have seen discussions about “Agent announcement” patches. The two particular ones that I remember were implemented with the agent.conf parameters of ‘preackannounce’ and ‘acksound’.

Are these patches safe to add to a production system? What gotchas are there, if so.

Is there any plan to include this functionality in an Asterisk release?

Thanks
