FINALLY, after 1.5 month, 3 installation (2 failed), total 10xTM installers/staff, numerous calls/complaints/hours, 1xCFM letter, 1xTM letter to P1 .... then only I get my P1 Fiber ForBiz
Somemore there is NO new fiber line installation & NO change of BTU for me as an existing UniFi user, and I have to go through all these
nonsense bloodly journey with TM ......
Obviously, TM is the main culprit in my case, they could have done it remotely without the need to deploy anyone on site for any existing UniFi user....

After some struggling work last nigth (I'm not expert in this)

, managed to get both WAN running:
But definitely the dual-internet is still not perfect, am still struggling to research/fine-tune ....
Generally at this moment, both the internet lines speed seem to be the same, I do notice the P1 has slighly higher ping than UniFi, but it's very minimal in my case.
Btw, to use own router and make the P1 stock RG act as VoIP only (vlan.920) per above diagram, need to setup as follows:
I've just tested it on my RB750 vlan.920 bridging to P1 RG, the VoIP works!
Actually I'm thinking whether can do away the stock RG completely, wanted to test the VoIP on my
Yealink SIP-T20however P1 didn't provide my SIP account details during installation, so I called P1 to request, now waiting for them to provide .....
That's all my experience sharing now, enjoy P1 folks!
