I would love to use my Mikrotik router over the original Thomson router given by Maxis. I manage to configure my Mikrotik router to establish a connection with the BTU but my problem is, I can't get my VOIP phone working because the port is on the Thomson router

I think it is case to case basis. Some people stack the BTU and router, place it in a hot/pack area, etc. As usual, any IT related component if exposed to long term heat will cause it to be unstable and malfunction.

My advice is NOT to stack the BTU/router and try to put it in a place where it's exposed to open air. This is recommended if you want to turn it on 24/7

I was given Alcatel Lucent BTU which does not have a user interface like Huawei Anyone knows how to telnet or access the BTU so I can use my own router for data?

I manage to configure my Mikrotik router to make a connection and it works The problem is, I cannot use VOIP because the phone port is connected to the Thomson router. Any ideas how I can get VOIP working?

If that is the case then I need to logon into Thomson and turn off DHCP and change it's IP address I can't seem to find the right command to change the IP address for Thomson router. I wonder why they give us all these troubles, sigh.
