Configure Quality of Service on a Cisco 3800 and 2800 Router

I have two locations with the IP Addresses of 192.168.3.0 and 192.168.5.0.

I would like to configure Quality of Service between the two locations.  Between the two buildings we will have Two T1 Lines.  

Would it be better to share the two T1's and configure Quality of Service or dedicate one T1 for data and one for Voice and set Quality of Service on the Routers?

Can someone give an example of how to set Quality of Service on the Routers in two locations.

Also, will this effect any other network protocols such as EIGRP between these two buildings and a third location.


Thank you for any help!

Here's the senario...

One Router will be connecting to 3 other Cisco routers.  Two out of the three will be passing voice as well as data.  

Router 1 ---> router 2 voice and data (Multiple T1s)
Router 1 ---> router 3 voice and data (Single T1)
Router 1 ---> router 4 data               (Multiple T1s)

Between Router 1,2 and 3 voice is the most important traffic.
Between Router 1 and 4 data is the only traffic.

How would you go about setting this up?  
I've gone through those links and one of the sections said to run ip cef with EIGRP or IGRP.  


Thanks.
That depends on where your voice is coming from. Do you have an IP enabled PBX at each location, at just one location with IP phones, or are the routers themselves making the VoIP calls? Are they analog phones or IP phones? How are you setup internally? Do you have separate vlans for voice and data?

Here's a good reference document on load-sharing with 2x T1's with CEF. This example uses OSPF but EIGRP works just as well.

"Related Information" at the bottom of that doc has more links to other documents like how to set it up.

Two locations have enabled Phone Systems that handle the Voice over IP (the phones are digital) and the third location has a handful of Voice over IP Phones.  (The third location is a small building with about 7 VoIP Phones)

The way the phone systems are setup is that only the Phone System itself is on the network.  

For our Dial Tone we have Two PRI's coming into location #1.

Location #2 and #3 will be connected to site #1 and make their outbound calls through site #1 as well as interoffice calls.

No Vlans on the switches.


Thanks
