Universal Intercom Incompatibility with Cardo Headsets

Hi, 
I can´t pair my Sena 30K (P/N 30K-03), using the Universal Intercom with any Cardo from the last Generation. I proceed with Universal Intercom from Sena side and Phone Pairing or Intercom Pairing in the Cardo side and both don't work. The only way that can these devices pair is Cardo in Universal Intercom mode and Sena in the phone pairing. This is not useful for this device because I can´t add any other device to talk together.
