[OpenSIPS-Users] Handling of non-SIP messages

[Taner Sener]

Hi Iñaki,

I'm using tcpdump to see UDP messages. Using

tcpdump -i eth0 -n -s0 -vvv udp port 5060

i see the following message. A message containing text 'default send
string'.
-----------------------------------------------------------------------------------------------------------------------------
14:13:55.973673 IP (tos 0x0, ttl  64, id 52296, offset 0, flags [DF], proto:
UDP (17), length: 49) 10.10.7.10.42042 > 10.10.7.7.sip: [udp sum ok] SIP,
length: 21
    default send string

    0x0000:  6465 6661 756c 7420 7365 6e64 2073 7472
    0x0010:  696e 670d 0a

the following trace belongs to a SIP OK message sent to opensips:
-------------------------------------------------------------------------------------------------------------
14:18:52.634149 IP (tos 0x0, ttl 128, id 19912, offset 0, flags [none],
