Hey all,

  Hoping to get a little advice. I am about to roll out a new project at a remote site. The remote site will consist of a dedicated T1 circuit back to HQ This will actually be 2 bonded T1's. The remote site has no server what so ever, no direct connection to the internet, no dns, dhcp etc. The remote site will consist of cisco IP phones and some PC's. It should look something like the below diagram.

              HQ                                                               Remote
                | --------------------------------------------|
         Cisco 2851                                 Cisco 2811 (Networks will be learned via EIGRP)
                |                                                                       |
   Cisco 6509 switch                Cisco 3560G   Vlan's 2,3,4,5 (4&5 are Voice) VLAN 100(MGMNT)
                |                                                    /        \----Fiber
   Call Manager/Unity            2 2960's Stacked     single 2960
                                                                 |                          |
                                                      VLAN's 3&5          VLAN's 2&4

I'm a little confused as to where I would configure DHCP for the IP phones and PC's at the remote office to reach the Call manager/Unity servers and also for the PC's to get internet?

Here's what I have so far for IP's on the 3560 at the remote site
vlan 2 = 10.2.2.1/24 - Data
vlan 3 = 10.2.3.1/24 - Data
vlan 4 = 10.2.4.1/24 - Voice
vlan 5 = 10.2.5.1/24 - Voice
vlan 100 = 10.2.6.1/24 - MGMNT


2811 fa0/0 connection to the remote local lan = 10.2.6.2 - port in Vlan 100
2811 multilink T1 interface = 10.2.7.2
2851 multilink T1 interface = 10.2.7.1
2851 fa0/1 port is configured for vlan 61
6509 mgmnt vlan = 10.1.61.1

Can this setup work with what I have? Any help is appreciated.
