It is hard to tell from the above information what may be happening. Lets start with your configuration.
- Do you have a UDP virtual server listening on port 5060?
- Do you have a SIP profile attached?
- Does the SIP profile have the option Insert: via Header option selected?
- Is the virtual server using SNAT?
See SIP Profile from the manual for 11.2

Please show tcpdump command you use.

Please use tcpdump -i vlan_name host x.x.x.x and see if that works for you.
