This observed events descriptor "30 15 80 04 00 01 00 01 a2 0d 30 0b 80 02 00
01 a1 05 04 03 0a 01 02" is decoded wrongly:

   ObservedEvent
       eventName: 00010001  Generic H.248.1 Annex E (0001)
           Package: Generic H.248.1 Annex E (0x0001)
           Event ID: Cause (1)
       eventParList: 1 item

               eventParamValue: 1 item

               eventParamValue: 1 item
                   Generic Cause: UR (Unavailable Resources)
