[cisco-voip] SNMP number from 3800s

[Norton, Mike]

I dunno… In my environment, I get a lot of <20 second calls. “Hello, school? Little Johnny won’t be in class today. Okay, bye.” The chance of that not landing on the 2-minute boundary seems good, especially if there’s a lot of it.

yeah, but it also has to mean that these <2min calls are always happening in between the 2 min cycle, which seems very odd.

I don’t think it’s that odd. If it’s double, then I interpret that as basically meaning that for every call >2 minutes, you also have a call <2 minutes. Doesn’t seem unreasonable to me.

I'm using the following two OIDs to get call status information from two 3800s using MRTG with 2min captures.
1.3.6.1.4.1.9.10.19.1.1.4 (the total number of lines in use)
1.3.6.1.4.1.9.10.19.1.1.8 (the high water mark, max lines in use)
I've recently reset the high water mark (thanks Mike), but I'm seeing about double the use of channels with the high water mark vs. lines in use. I know that with a 2min grab, you're gonna miss some, but this seems odd.

Anyone else see this sort of behaviour? Are we actually using that many lines?
