[VoIP] Cisco 3810's

[Shane Young]

The docs say the can do DP as well as DTMF.  I'm curious to see how  
well that works as some of Cisco's other stuff doesn't do DP very well.

I think this is available in many different configurations, but yes,  
it seems that you could use it as a simple voice gateway in front of a  
channel bank, or just use the analog ports on it.

You might need to configure it "statically" in your Asterisk system.   
I don't know that the code for these supports registering like an ATA  
does.  That is one of the things I want to find out when I get them.   
This is easy to do when you are on the same LAN, but if you want to  
put it behind something that does NAT *and* may change it's WAN-Side  
IP address, it could be a little more difficult.

In an ideal world, these could be packaged up for non-IP savvy  
switchers to tandem off of somone elses system.  Just send out the  
3810 pre-configured and ready to go!
