Maxis VOIP phone not working tried on 2 routers.

Need help, sorry for disturb. But trying searching also unable to solve. Even bought 2 Router to try (Tp-Link AC3200 and Asus N300 RT-N14UHP)

I have been trying the way from Maxis Custom Router setting by connecting LAN 4 (AC3200) to Thomsen WAN, but THOMSEN still not able to link to Telephone.


And try Asus from the Asus Router to Maxis Home Fiber by connecting LAN 3 (N14UHP) to WAN of Thomsen. Still no luck.

Hope any of you can help me. or I can open Team Viewer to check my setting

I did try the way posted by Peacelover1992 Post #01, but I'm unable to connect to Huawei EchoLife HG850a setting page to do the setting.

All above, tested on above 2 routers, I'm able to connect to Internet, just the VOIP phone no connection.

Your help are much appreciated.

Many Thanks

Teo
