Welcome to the world of ALG.
This is most likely (the way I see it) a Application layer Gateway (ALG)
that kills your signalling.

On SER 0.9.6, we get the following logged when a user
with an X-Ten Eyebeam softphone tries to register (IP addresses have been changed):
May 8 17:31:18 test ser[8877]: ERROR: parse_via: invalid via - end of header in state 6

An ngrep trace shows:
Via: SIP/2.0/UDP 1.2.3.4:35955;branch=z9hG4bK-d87543-2667f342e0038805-1--d87543-;.
Has anyone seen this before? Is there a change for either SER or Eyebeam to make them
work together?
