Guillaume,
your understanding is correct. These traps are not handled by IRSNMPTR collector and hence we look for specific traps in the contact center collector.
VARBIND:1.3.6.1.6.3.1.1.4.1.0 MATCHES %3.6.1.4.1.6889.2.17%
Also, count of all these traps is used to feed into SNMPTPCT field of ACCSUM summary record. It is however not used in threshold. But if you ever wanted to alert when an AEP has more than X total traps (all seventies), then it may become handy.
Let me know that answers your question.
