Hello Robo242,
welcome to the Polycom Community.
The only supported configuration if using LYNC / Skype is to set the phone to Base Profile LYNC. If set into this mode only one line can be registered.
If set to Generic Base Profile LYNC / Skype is not supported and multiple SIP lines can be registered.
There is currently no hybrid support.
