Integrate Cisco CP-9951 IP phone to work with current Yealink IP phones using Maxo.com.au hosted pbx SIP

We use [login to view URL] Hosted PABX with Yealink SIP -T22P phones; self install and was easy to set up. I have since bought 10 Cisco Handsets CP-9951 phones (with video function) and wish to add them to our network. With no experience with Cisco phones, I now need someone to show me how to set up one of the phones to add to our hosted PABX. You need to provide the solution by screen shots of how to set up and /or video. Or we can work through the setting up via Team View once you have a solution. The project can only be considered successful and concluded once the Cisco phone can make and receive voice and video calls. You must have experience in doing such a set up in the past with proof.
