Audio from 2 different sources?

its not failing... the usb headset currently works. i want to add a secondary device that i can hear out of. thats it

If you change from " attach a second source to listen to the calls " to " add a secondary device that i can hear out of. " then you changed the spec.

Why can't you wire in a second set of headphones? It's basic electrical tech work.

if i owned this equiptment, i definately would try that. unfortunately the company owns these headsets and they run around $75 each. that would be an expensive lessons if by chance i messed up. any other suggestions besides modifying the actual hardware?

Not to dismiss that as cheap, the work is basic electrical stuff I'd expect your first year electronics college student to get done over lunch.

--> But here's the problem. Your first post and title differs from your later post as to the want or need.

As to USB switching and more, while I might expect a guru embedded designer to craft up a solution in 3 to 6 months the cost would easily reach 5 figures. This is why the old school analog solution should be considered here.

it might be cheap but slicing together 1000 headsets would take quite a bit of time. as for my first post, sorry that it wasnt clear but my followup post is what i need a solution to... which from what i understand... there is none?

My work involves writing up a document to make such cables. So from my vantage point the only thing that stops this from getting done are the folk that must have it done.

If this is your old need to listen in on the content issue, the old analog solution is the cheap exit.

-> But I have a question. Why did this company buy 1000 headsets that would not do the job?

Someone goofed on the spec.

thats a great question. there apparently wasnt much forsight in that decision was there? so we have a softphone system where our call floor receives calls through a program called Five9. their program isnt capable of running 2 usb softphones simultaneously. we have to use 2 computers to train 1 person. pretty lame huh?

We pay something less that 250 for a netbook for a training system so all the time and effort into fixing software at what is a few thousand is often dismissed and we pull in more PCs.

Sounds like the old balancing act.
