After playing around with the new firmware (and new SER cvs snapshot 0.8.12dev-22-tcp_aliases) I'm seeing some very strange behavior from SER (ngrep trace follows):

^^^^^^^^ Is there really garbage before SIP or is this a ngrep artifact? (a tcpdump -s 1514 -w /tmp/dump would help) Apart from this the reply seems ok. It is fragmented and the whole message is huge (25017@0:1480).
Maybe the ATA doesn't deal well with packets this size, or a firewall drops the fragments.
