Lots of Active Lines

Total active calls 163

Total active channels 163

I only have 8 Lines, and it is using about 2mb of upload. Anyone have any ideas?

With that huge amount of information it would only be a guess.

How about you start by reading this post:

Then tell us about your system and post the output of ‘core show channels’ and ‘sip show channels’ please.
