Creating static IPs on Cisco 851w

Is there a way to create static IPs through the web interface on a Cisco 851w? We are putting in a new phone system and the phone vendor needs three static IPs from us. Management is trying to accomplish this without hiring a high-priced Cisco certified tech. I have experience with configuring home routers, but no experience with Cisco, command line programming or the interface cable. I have gotten into the web-based configuration and looked around, but wanted to ask before proceeding.

Any help greatly appreciated!
 
provide static ips? wouldn't you just program the phones to have said static ips ?

if you are trying to setup a dhcp that gives the same ip address at all times to the same hardware, then yes you could do that:
!create a pool:

ip dhcp pool Wireless
import all
!define your ip pool here.
network 10.254.254.0 255.255.255.248
!your gateway is defined below
default-router 10.254.254.1
!your dns is defined blow
dns-server 4.2.2.2
!
ip dhcp pool PHONE1
import all
host 10.254.254.4 255.255.255.248
!you can also use hardware-address which would be
!mac addy of your IP phones
client-identifier 0100.2163.8a24.0e
dns-server 4.2.2.2

through SDM you should be able to achieve something similar, however my experience with SDM and 850 series was pain in the a$s.

are these phones connecting to a SIP sever? is it internal ? do you also need NAT setup?

We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.
 
I think what they are asking for is for you to exclude 3 addresses from DHCP on the voice subnet and then tell them what those 3 addresses are.

In your position, you should be asking for a detailed design before making any changes - this will protect you from any mistakes you may make when asked to guess WTF it is they want.

The voice implementers are often quite ignorant of IP networks and they try to just slap it in - their design should identify two seperate networks: data and voice. they need to be seperate on account of the voice quality of service requirements (QoS).

Make sure you know their design before starting to make changes.
