Pinned topic SIP/2.0 482 Loop Detected

‏2011-05-12T13:10:16Z |
Hi,

We're experiencing some SIP/2.0 482 Loop Detected on INVITES and INFOs. The strange thing is that we only start to experience the issues under a certain load (I wouldn't say high load), maybe this just increases the chance of us getting the issue.

Any ideas?

WAS logs:

    This looks like a MAC forwarding configuration issue at the SIP proxies but we are awaiting more info on this one.
