Hello H&R,
there is a huge difference between a bug aka something broken on our end or simply a feature not 100% working or ever tested on an open source platform.
Asterisk uses the Attendant functionality as described in this FAQ post:
Jun 29, 2015 Question:How can setup a Call Park Feature using an Asterisk Server?
Resolution: Please check => here <=
As there is no Feature syncronisation between the server and the phone this may be the result of being able to connect two people together.
Someone from the open source community would need to work with Polycom engineering to either utilize a functionality which we already use with our interoperability partners like Broadworks or provide a relevant business case to create a new functionality.
At least you should open a support ticket via your Polycom reseller and provide a working example from another SIP phone and then in comparison your failing example.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
