It is sometimes possible to meet a multi-vendor and multi-client environment. For VoIP networks is not good but happen. A Network Admin can automate switch configuration in order to not provide the configuration of each individual phone and allow the voip team to install the devices by themselves.
In this example we have an HP A5130 switch a CISCO IP Phone and an AVAYA IP Phone:
