Re: [SR-Users] NATDETECT Flag 16

I have a doubt about the flag 16 used in nat_uac_test() belonging to the module NATDETECT.

In the documentation, the following is stated :

*16* - Test if the source port is different from the port in the “Via” header

I have some situations that I receive a request from port 5060 and the Via Header contains no port. I think it probably assumes that it is the default port.

Will this situation trigger the "16" flag ?

Hello,

I haven't tested it for you. :-)

But as I look to the code, it should then assume that its the default SIP port 5060.

nat_uac_test -> received_via_test -> check_via_address: "if (port==0) port=SIP_PORT;"

Best regards,
