LLD discovery with SNMP (What OID string to use)

[SaraXxin]

Hi there.

I've been struggling to get my discovery rule working and I'm really hoping someone might be able to assist me.
I've managed to get a whole range of errors depending on what I try use and I'm currently at the point where I'm getting the below error.
It's pretty obvious as to what's wrong but I don't know what to do in it's place? I've followed the guide as per the below link as well as some suggestions on forums etc.

https://www.zabbix.com/documentation/3.4/manual/discovery/low_level_discovery/snmp_oids

This is the current error on the log.
12858:20181220:141449.179 item "vibe01.convergedgroup.net:vibeRemoteQuality" became not supported: Invalid SNMP OID: macro "{#SNMPINDEX}" is not allowed.

This is my OID string.
discovery[{#SNMPINDEX}VOIPEX-VIBE-MIB::vibeRemoteQuality]

This is the info I get back when I run snmpwalk

root@dev-zabbix:~# snmpwalk -v2c -c 'converged' -m+VOIPEX-VIBE-MIB 10.255.2.50 vibeRemoteQuality
VOIPEX-VIBE-MIB::vibeRemoteQuality.1 = Gauge32: 65535
VOIPEX-VIBE-MIB::vibeRemoteQuality.2 = Gauge32: 65535
VOIPEX-VIBE-MIB::vibeRemoteQuality.3 = Gauge32: 0
VOIPEX-VIBE-MIB::vibeRemoteQuality.4 = Gauge32: 0

I have also tried several discovery rules using the actual OID but still no luck.

Please if someone could give me the correct string to use I would really appreciate it!
