I'm getting an odd Via parsing error from SER 0.9.6:

When I look at the packet, it looks like the actual SIP data is somehow getting garbled... with odd characters showing up in the middle of headers, etc.
Any idea what might cause this?

All these things look garbled. Would this be a transmission error of some kind (the garbled headers are identical for each submitted packet, though, so it seems unlikely) ?

Unfortunately, it's not my UA, so I've no idea. I just happened to notice this in the logs, and started sniffing the packets and noticed this weird issue with the garbled data.
It caught my attention as we've been getting hit CONSTANTLY with fraud attempts through our service from various hacked IPs (proxied through). Most of them originate in Egypt, Jordan, Morocco, and Palestine, but lately, we've seen the IPs from all over (Germany, Sweden, Korea, etc). Some of these have been proxied and attempted 'manually-created' headers to try and fool our system. This caught my eye and I was wondering if there might be a legitimate reason for it before I disabled the account out of sheer paranoia. :)
