I have noticed this not sure if is just a limitation of IR Prognosis But I have noticed since that there is difference in the ability to monitor IP Groups or Trunks on a AudioCodes compaired to Sonus / Ribbion. Here is a example I have gone through the configuration guide and set this up to use RTC-XR and SNMP and noticed that first a few things.
1. Description Field doesn't work on AudioCodes SBC's older than 6.8 firmware its because the SNMP value changed after the 6.8 firmware. I have a request for a fix for that.
2. I noticed that everything right of Status in this screenshot has never populated with data or gives me how many sessions there are on that trunk / Signaling Group.
Currious if I am missing something or just a limitation to AudioCodes Monioring.
Thank you for your posts.
1. As you already have a ticket request fix for Description field not working on AudioCodes with FW older than 6.8, I will leave it with your Support engineer.
2. My understanding is that Prognosis obtains "In Attempts", "Out Attempts", "Out Failed" and "IN Failed" stats using the following table in AC-PM-Control-MIB:
acPMSBCIPGroupInAttemptedCallsTable OID: .184.108.40.206.4.1.5003.10.8.2.54.3
acPMSBCIPGroupOutAttemptedCallsTable OID: .220.127.116.11.4.1.5003.10.8.2.54.6
acPMSBCIPGroupInAdmissionFailedCallsTable OID: .18.104.22.168.4.1.5003.10.8.2.54.12
acPMSBCIPGroupOutAdmissionFailedCallsTable OID: .22.214.171.124.4.1.5003.10.8.2.54.15
You may validate the values by snmpwalk these tables to the SBC, and that should confirm if Prognosis is reporting what it recieves.
I also include Supported UC platform link below for your information.
