"If you need to use the 5366 for Optus VoIP you can have it behind the Asus you just need to port forward 5060-5061 UDP & TCP, and disable SIP Passthrough on the Asus."
Hi so I am currently not using the Optus supplied modem\router (f@5366TN) but i am using the Asus RT-AC68U with a Technicolor Moden, so i don't currently have VOIP functionality.
Reading this post from what I am getting is that we go from (in my case) the modem into the Asus router as the main router then plug the 5366 into the Aus router and forward ports form the Asus (5060-5061) to the 5366 both TCP and UDP
Then disable SIP passthrough on the Asus, and obviously the phone would be plugged into the 5366
Have I got that straight?, this will really help there is 3 of us with the same setup and the same issue
What type of NBN connection (FTP, FTTC, etc) do you have?
I'm assuming you are on either FTTB or FTTN since you are using a Technicolor Modem, is that correct? If so, is the Technicolor Modem in bridge mode?
Hi, yes we are using FTTN and the have bridged the Technicolor
OK, so nothing needs to be done to the Technicolor.
I assume this whirlpool post is from one if your group. RedSector's first set of instructions spells out what needs to be done. While he stated he needed to disable RTSP Passthrough I did not have to do that, and I've been running Optus VoIP fine since late last year. He correctly states that you only need to do port 5060. My reference to 5060-5061 is incorrect as that was based on some conflicting info I was getting at the time.
My FTTC setup is: NBN Box->Asus RT-N66U->PAP2 Voip Adapter
