Most SIP routers with in-built ALGs that old are probably poor implementations. It may well have messed about with the SDP offer but not changed the content length in the SIP header. I use Draytek's and frequently find I have to change the local SIP port to anything other than 5060 to stop it messing about with the signaling. FreeSWITCH does a much better job at NAT traversal from the far end than most modems can achieve at the near end. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Reasons-for-a-SIP-2-0-400-Bad-...
