Do you purchase the UTAM credits (Radio credits?) directly from UTAM, if so does anyone know how much they cost? Also I am installing companion phones on my MICS XC4.1 and do not have a Companion ID number, where do I get this (UTAM or Nortel). The install guide says you need the Companion ID Number before contacting Nortel to purchase the system credits and activation codes. Also do I just purchase from UTAM 2 credits for each base station?
