Can anyone tell me what the CISCO-ISDN-MIB: ciscoIsdnMIB value (OID:1.3.6.1.4.1.9.9.26 ) polls. There isn't a description in UnDP for it. Also can anyone provide me with the OID for number of active calls on a voice gateway ( CISCO 2821 router). We are running orion npm 9.1 sp3 on our network.Thanks
