The Xorcom product range are pretty handy for this. You can plug in to your box via USB and they look like Dahdi extensions, so you can see state change etc.

I had some issues with the latest kernel, but other than that they are great in the hotels
They are externally powered and have modules within the chassis so you can get a large chassis then add lines

We are using a 32 port in one hotel happily. 

I find the SPAs horrible to debug if there is an issue to do with actual call. They do work, but if something is not quite right with a call its really hard to see whats happening. 

I prefer to be able to see everything on the CLI

Cheers Duncan
