I hope this is not an FAQ, I've tried searching
the available info. Using
Ser 0.8.12, Cisco AS5300 with IOS 12.3.6 & a ATA-186.
ATA-186 (behind NAT) -> SER -> AS5300
On the INVITE, we get:
10w6d: httpish_msg_process_network_msg: Content Length 261, Bytes
Remaining 256
10w6d: HandleUdpSocketReads: SIP Message incomplete, trashed
If you are using Cisco NAT, I'd suggest sticking a sniffer either side of
it and checking it's not trashing things. The default Cisco NAT helper, at
least on some IOS versions, is less than helpful and trashes packets
(specifically truncated SIP_INFO packets so that their content length is
zero). This causes incomplete packets. Turning off nat-helper fixes this
(it is on by default).
