Cisco seem to sell two different types of device license units with one being for Cisco devices (e.g. LIC-CM-DL-100
) and the other being for third party SIP phones (e.g. LIC-3PTY-DL-100=
In the CUCM6.0 System > Licensing > License Unit Report window the system does not seem to differentiate between the two types but just lists Phone License Feature units.
My question is therefore is it important which type of DLUs I buy and, if I buy the one for Cisco devices, are they usable with third party SIP phones and vice-versa?
