Invalid enum CallingPartyCategory ?

[kpouer]

/kind bug

What happened:
The interface org.restcomm.protocols.ss7.isup.message.parameter.CallingPartyCategory seems to have an invalid value :
byte _PAYPHONE = 14;
but if I read the Q.763 3.11 it seems the good value should be 15 :
0 0 0 0 1 1 1 1 payphone

14 is 0 0 0 0 1 1 1 0 IEPS call marking for preferential call set up

thanks
