I wondering if discovering analog voice interfaces is intended on Cisco
platform or this is just bug?
Currently discovery will add interfaces with media type - voiceOverIp,
voiceFXO, voiceEncap, these interfaces doesn't provide any statistic
over snmp, except UP/DOWN state. So I see no reason to draw graphs for them.
Even better I'll be glad to get rid of them from regular IP ports, maybe
move to different group, or just have option to ignore state/don't poll
them?
