I'm working on a custom SNMP probe for Cisco AS5300's that displays active SIP/PSTN call legs.

 

If I use snmpwalk from the OID .1.3.6.1.2.1.10.21.1.3     I see the first 4 entries are as follows

 

transmission.21.1.3.1.1.3.242813078.1 = "2125551234"

transmission.21.1.3.1.1.3.242813083.1 = "2125556789"

transmission.21.1.3.1.1.4.242813078.1 = ""

transmission.21.1.3.1.1.4.242813083.1 = ""

 

I see the numbers of both calling and receiving, and some other info.  However, part of the OID (242813078) is the time tick the call was created.  I don't find any OID that references all the time ticks that calls were created, so my only solution appears to be to use snmp-get-next to get this info, but how can I do this in a custom probe?  And how can I neatly display the results?
