I’m having a very real problem with SIP channels not hanging up at one particular site… they have the exact same hardware/config that we use everywhere, nobody is experiencing problems like them, and I can’t find what’s causing the problem.
This appears to be a station-side problem, but does not matter if the extension is local or remote. I’m getting open channels with all extensions.
Here’s what I’ve done
Replaced entire chassis, hard drive, etc.
Originally TB 2.2, then did fresh build of 2.2.1
Replaced router
Moved from Cable to T1
P.S.
I’ve provided sample logs/conf below, and if you look specifically at the ‘sip show history’ xxxxxxxx, I think that’s where the problem lies (notice the 487 and continuing ACK)… I just don’t know what to do about it.
Any ideas?!?
