Routers, Zen & Landline handsets

Flyingkidney

I've just switched to Zen & one of the things then engineers didn't check was the landline.
So far we can get incoming calls, but trying to make outgoing the phone reads 'line in use'
So can anyone recommend a good, reasonably priced VOIP phone other than Zens own recommend.
Also, routers, it seems co's are tying in routers, or restricting them these days. Has anyone upgraded/changed routers with Zen?
I've grown up with the web being a little more flexible, you got your deal, you could change routers!

So you are using your existing phone plugged into the Zen router and it doesn't work for outgoing calls? What have Zen said about that?

Yes, no dial tone, just the 'bips' and a message onscreen saying phone line in use.

Basically they've said 'I probably need a new handset'. Having gone through all the troubleshooting with them via phone. It is a relatively old handset, but I was assured it should work before taking the contract.
