This is the Cisco IP Phone Biggest Feature of all
Video Conference is one of the Major thing in Business were Some Employee reside in another City and you can save time and Money with Video Conference and for Some Business an MCU is not an Option.
The Best thing for it to work You don’t need TelePresence or Meeting Server, All what you need is a PVDM3 Modules weather it PVDM 3-128 or PVDM 3-265 in your Router and Configure the Conference in the IOS Similar like you do the Normal Conference i already Explain it in an Earlier Blog
I will be configuring Video Conferencing for Cisco 8941 IP Phone and 2 of 9971 IP Phones.
So Let Start Configure the IOS
first i Set the DSP reservation for voice related services Integer is a percentage which is 60 in this Example, That Leave me with 40% to video resources
Then Configure the Video Conference Profile
Its Important to Define the conference-participants parameters and Maximum Sessions so I Define how Many Parties Per Conference and I define Also the maximum sessions
Now the SCCP Configuration Part
i Define my Call Manager
and here i Associate the Video Conference Profile to the SCCP Group
Now the CUCM Part
Go to the Media Resource – Conference Bridge – Add New
Then Go to Media Resource – Media Resource Group – Add new and Select the Video Conference Resource that you Just Configure
Then Go to Media Resource – Media Resource Group List – Add New and Select the Media Resource group
Finally Assign the Media Resources Group List to the Device Pool
Now make a Call to from Phone A (7156) to Phone B (4119) then i Add by Using the Conference Button and Add Phone C (2131) and Press the Softkey Conference and Just Like that you have a Video Conference
