External Alerts for Calling Groups 1

A quick question regarding external alerts for calling groups. I designated analog exts as external alerts for two calling groups, planned to just put ordinary ringers on them. I set the threshholds all to 1. An SLT on these ports can make calls etc., no problem. However, with calls queued, they don't ring. Any suggestions what to check? Seems like it should be straightforward enough but obviously I have overlooked something.
 
Well now I feel silly :) Thanks for the help.
 
Don't feel silly: Jack is smart and this is how he put bread on the table for many years.

Also don't forget that an external alert could just as easily be a police light, strobe or other silent flasher. I don't know if that suggestion is meaningful to you or not...all I'm saying is that it doesn't have to be a bell or horn. Sorry if you already knew that.

Thanks, Tim, I was actually thinking a strobe would be best here - continuous ringing when there are a lot of calls would probably drive everybody nuts.

Unfortunately it is probably a moot point. I have ports on 412 cards available, and 016 TR stations available, but no MLX ports, and no open slots, and it probably isn't going to be worth adding a cabinet over. As I understand it, that means I'm not going to have external notification on this system.

Hope this doesn't violate any forum spam guidelines but let me pass along a nice bargain, at least something I can do to pull my weight around here :) I like to keep some ringers in stock and at this price I can afford to:

 
We actually used a 4400 TDL "Single Line" phone as an external alert once. It didn't so much ring as emit a continuous tone when activated. Placed outside of the immediate area, it could be heard but not obnoxious.
 
I had a customer who had a remote site that was supported by an MCK extender. As such, he only had 44xx sets to work with. The site had sheet metal machines running all the time and desperately needed an external alert.

I solved it by buying this funky little VOX type product from Viking, which I wired in parallel to a 4406D's speaker. Call the extension, ring is "heard" through the speaker which causes the VOX to trigger a loop closure and activate a strobe. It works surprising well. I'd also considered skipping the "surgery" of the 4406D and instead use the headset port. It's another way to squeeze analog from a digital set, but you have to keep the headset active. Anyone wishing to answer the phone would have to first hit the Headset Status button before answering, which I thought was a bit messy.

I've got just one customer that has alerts for Call Queue depth, but I don't entirely recall the challenges behind it. I KNOW that I had to call Jack to ask him a few questions about it for sure. Anyway, if it's not going to be used as a Queue Alarm, maybe there's another way around it with an alternate like Tom or I have suggested.
