assuming thi sis xslt1, you need two keys
1st level

<xsl:key name="byObligation" match="BillDetail" use="OBLIGATION_ID" />
second

<xsl:key name="byObligationAndPhone" match="BillDetail"
use="concat(OBLIGATION_ID, PHONE_NUMBER)" />


then just muenchian group as usual

<xsl:for-each select="BillDetail[generate-id()=generate-id(key('byObligation',OBLIGATION_ID))]">
 this is the group for <xsl:value-of select="OBLIGATION_ID"/>
 now further group this by phone
 <xsl:variable name="OBLIGATION" select="OBLIGATION_ID"/>
 <xsl:for-each
 select="../BillDetail[generate-id()=generate-id(key('byObligationAndPhone'
         ,concat($OBLIGATION,PHONE_NUMBER)))]"/>
  whatever
...
