This started out as a firewall issue. I had reports that a remote site (connected to HQ by VPN) was having to reboot their firewall at least once per day because they were losing connectivity. After looking at the ASA 5505's connections table (show conn), it became clear that their ATA 186 and the ATA 187 at the site each had thousands of idle connections to CUCM (which is located at HQ) in the connection log. The SCCP phones, PCs, etc. all have normal numbers of connections on the ASA. It's just the ATAs. The ATAs are always using port 1031 on their side but going to thousands of different ports on the CUCM server. Any idea why the ATAs might be doing this?
That was it. I'm still not sure why two ATAs were capable of creating 20,000 idle connections faster than they could be flushed out of the ASA's connections table but as soon as I registered the 2nd ports on them with CUCM and reset the connections on the ASA, I never went over about 400 connections. Thanks for the help.
