Yes, our plan is to order a PRI/T1 with 24 channels of voice from the  
local telco and connect it to an ethernet device called a "Primary  
Rate Interface (PRI) ISDN gateway"
the list of choices is here:

I believe that a cisco 2600 router with a NM-HDV card install is one  
of the choices. I am still researching this topic.

Plain Tiger is fine. (see Ken's email)

We thought about the linksys, but I already love the 7960 cisco phone  
and they are only about $160 on ebay these days.

Yes, for testing and for some remote calling for travelers.  Have you  
tried LoudHush ? I like the idea of an IAX based softphone since it  
seems like IAX is gonna be better through various firewalls.

Yes, lets get a dialog going.

So far, we have Asterisk 1.2.10 running on os x server with about 13  
cisco phone connected,  the main issue is we have a link from the new  
system via an SPA 3000 and and SPA-3102 to allow people on the "old"  
phone system to call the new one, This works, but we get a lot of  
line noise, and dropped calls, etc. This bridge to the old phone  
system will go away when we fully deploy.  The other issues are the  
timing issues with music on hold and meetme
