Hello,

do you use force_rport()? Normally, the reply is routed using Via header address.

Cheers,
Daniel

Hi,

I really do not know what is happening but when I'm sending SIP INVITE form port other than 5060, if it reaches sl_send_reply("403","Forbidden") response is sent to 5060 and not to the source port of the initial INVITE.

I am not changing anyhow $du or $rd ...

Mino
