Need to modify Via header


Hi,

I am running my SIP entity behind the NAT. I want to send the public IP in Via header by just modifying the "send-by" parameter with public IP so that we can receive the response on same IP . I did the same by modifying the Via but Stack fails and do not send the request out. It gives error as follows:

TransportSelector.cxx:1463|Can't find matching transport [ V4 172.23.71.224:5060 UDP target domain=unspecified mFlowKey=0 ]

​Please help me to meet my requirement.

​Thanks,
Alok
