SIP PROXY / REFER PROBLEM

[gastoncoustau]

Hello, first of all; i' m new in this forum so i' m not sure if this is the right place to post this question. I' m using a FortiGate 300 as a SIP proxy between my LAN and WAN. The problem is that when i transfer calls with the REFER method, the refers fields " refer-to" and " referred-by" are not ip translated; so the transfer does not work. Am i missing something in the configuration? is this issue solved in further versions? (it' s working in V4.0 MR3) thanks!!!
