Steps to reproduce:

1. I would like to receive SNMP trap from AudioCodes M1000 to my Zabbix server
2. I have set the trap community string and the trap manager hostname as Zabbix server
3. My Zabbix SNMP version is 5.5
4. I have configured this as host and added SNMP items as well
5. SNMP trap key is snmptrap[<regex>]
6. And configured the trigger as well

Result:
Still not receiving the SNMP trap

Expected:
