Auto provision static ip address for IP Phone

[chumphol homsuwan]

Customer wants to deploy cisco IP Phone 7821  and 8851 altogether about 370 units. As being service provider, they don’t have dhcp service in the network. They want to have a way to provision static ip address to ip phone in bulk. They don’t want to manually set static ip address  by pressing the button on ip phone.

They claim that other vendors (Grandstream) can do this auto provision.

In Cisco world, you only have two options, DHCP and manual config (directly on the phone)

They would need to take the phones, hardcode them, and ship them. Once they're reachable, they would require a 3rd party app for remote control if they need to change any setting.

you can do so but eventually you have to configured the DHCP but will be binded to specific IP address to desired binded based on the mac address.

Example for one phone

ip dhcp pool Phone1
   host 1.1.1.1 255.255.0.0
   client-identifier 01b8.bebf.2365.d8<MAC address of the phone>
   default-router 1.1.1.2
   option 150 ip <Call Agent IP Call Manager>

Other way create a scripts and bind all phone mac address with desired IP address and applied to the router.

For such number of phones the most scalable approach will be using static mapping file.

1. Create a static mapping file in txt format. For example

    *time* Nov 22 2011 00:52 AM
    *version* 1
    !IP address       Type    Hardware address     Lease expiration
    192.168.97.5 /29  id      0100.3094.c3e5.ab    Infinite
    192.168.97.6 /29  1       0030.94c3.e5ac       Infinite
    *end*

2. Upload the file to the router flash using TFTP

3. Configure DHCP services on the router to point to the file. For example.

    ip dhcp pool POOL-192.168.97.X
       origin file flash:/dhcp_mappings.txt
       default-router 192.168.97.1
       option 150 ip 192.168.109.201 192.168.100.101
       domain-name test.com

Hi All,

I am looking for a solution that can statically set ip phone's ip address in bulk, not DHCP ip-to-mac-address mapping reservation.

Do you have any ideas?
