Write down before changed anything old settings of tftp ip and call manager ip, extension, name or take photo of screen
Cisco 7962 to change tftp
Step 1 Choose SETTINGS
Step 2 Scroll down and Select Network Configuration
Step 3 Select IPV4 Configuration (if have)
Step 4 Scroll to TFTP Server 1 (there will be lock on top of the right corner)
Step 5 Enter **# to unlock (Settings unlocked)
Step 6 Edit TFTP Server 1: field, enter the IP address of TFTP Server (mostly Call Manager ip address 10.92.253.23)
Step 7 Edit TFTP Server 2: field, enter the IP address of TFTP Server
Step 8 Validate to save the entry
it will reload or reboot the phone and check correct extension and name on the screen.
Option 2.
if you can not see lock key at settings, reboot the phone or unplug the phone when you see configuring or configuring vlan press Setting and if you see lock at the corner press **# to unlock and change tftp ip address.

1. The bottom 4 entries are very similiar....The highlighted line means that if the router gets anything that starts with 791 it will send it down port 1/0:0 as the first preference, the line below states that as a 2nd preference use port 2/0:0. The following 2 lines state a similiar thing except this is for phone numbers starting with 792. What we can ascertain from these four lines is that the local numbers for this site start with 791 and 792.
2. The .T states that for anything other that 791 or 792 then the router will need to get more information from the Gatekeepers.The 2 IP addresses are the Gatekeepers. The Gatekeepers keep dial plans for all customers. More information on the Gatekeepers below.

GATEKEEPERS
The Gatekeepers keep a list of all numbers for each customer. When a customer router receives a request for a call and it is mapped to ".T" it will request more information from the Gatekeeper. The Gatekeeper translates a telephone number prefix to an Ip address and advises the router, the router will then route the traffic as per normal and the Gatekeepers participation is finished for that call.
There are 2 Gatekeepers
Paris 57.210.105.204
Reston 57.210.105.236
If you want to ping to Gatekeepers then you need to use the Loopback 323 address of the router as the source
The following website will take give you the information that the GK's use
http://57.210.105.230/voipvpnMgt/index.html
Login: gcsc
P/W: gcsc#gen
1. Go to VPN data and find your customer - click on the customer
2. Click on VPN site data and this will list all the voice routers for that customer.
3. Click on the router you require
4. You can now go through the tabs to find out more information.
Best info is under the "Site Gateway Group" which shows the max amount of calls allowed at one time, and the IP address of Loopback323 (voice loopback). This other good tab is "Site Extensions".

Cisco Interactive 3D Products how the cisco products look like b4 buying
Go to the CISCO site and type “Interactive 3D” and the model number of equipment you are interested in.
This is a fantastic tool that our engineers and support teams can use to see what the physical equipment looks like before they go to site. The model allows you to move, turn, tilt, zoom, measure, and do just about anything but physically touch the equipment. It will even demonstrate removal of cards and let you zoom in on
