Got it. Anyway it more looks like a Polycom problem cause it happens only first conopal connection with a RealPresence acting as a mini-mcu (being on call with a third party). On first conopal connection problem is present but if I do disconnect, restart conopal and reconnect to RealPresence everything works as it should. Also SIP connections works fine.
