Dual WAN with BSNL FTTH and VoIP

[networkwhisperer]

So I was hoping someone here could help or provide advice on something I'm looking to do:
I recently got BSNL FTTH as a back up broadband connection. It came bundled with a new BSNL number, delivered over VoIP.

I have an Asus ac87u set up to do dual WAN with failover between my primary broadband provider and BSNL FTTH as secondary. The primary connection comes in as PPPoE on an incoming ethernet cable, and goes directly into the ac87u's WAN port. The secondary (BSNL FTTH) is an incoming optical cable, terminated by a BSNL provided Optilink ONT cum router. The Optilink router plugs into the ASUS ac87u on one of the ASUS' LAN ports. I use 192.168.2.XXX as the subnet for all my devices; the ASUS is the gateway for this. I've put the Optilink on 192.168.1.XXX and it serves as the gateway for the secondary connection.

There is VoIP set up in the Optilink and an RJ-11 jacked cable that come out of the Optilink and into a POTS instrument for calls on the number that came with the FTTH.
From what I can make out, the Optilink VoIP end point is given a static IP on a 10.XXX.YYY.ZZZ private network, with the SIP server it's supposed to talk to also on the same 10.XXX.YYY.ZZZ private network

All of this works right now; I can make and received calls on the new number and the broadband fails over to the secondary when the primary fails.

What I'd like to do:
1. I'd like to avoid the additional hop (ASUS --> Optilink --> Internet) for the failover case, and get rid of the 192.168.1.XXX subnet entirely.
I'm assuming this would involve putting the Optilink into bridge mode and having the ASUS do the PPPoE etc.

2. I'd like to be able to use the VoIP number with VoIP apps on smartphones or IP phones on the 192.168.2.XXX subnet, and do the fancy things that SIP/VoIP allows.
In particular receive incoming calls on the VoIP number on any chosen device, and call out from any device etc.

So on to the questions:

0. It is possible to do both (1)and (2) together, correct? (Obviously I'm assuming it is)
1. A route between 192.168.2.XXX and 10.XXX.YYY.ZZZ will need to be added, correct? Is this all that's needed for a VoIP client on 192.168.2.XXX to reach the BSNL SIP server and make/receive calls ? (Assuming route is necessary but not sufficient...)
2. Will I need to run my own SIP server or something? (Does/can the Optilink act as a SIP Server or proxy by the way? I can see a Dialplan as an advanced configurable option in the Optilink's configuration interface)

What's primarily causing confusion for me right now is how to set up for the effectively two outgoing networks for the BSNL (the internet one and the VoIP one) in bridge mode, while not messing up the dual WAN etc...

Any tips/advice/pointers appreciated !

There's no VoIP on BSNL DSL from BSNL, it's DSL. We were all talking strictly about VoIP on FTTH aka Triple Play systems.

Is BSNL DSL also unencrypted (easily snooping possible like bsnl ftth unencrypted voip)?

Nope not 1 Billions idiots, they are people who are not so blessed in life to afford 500 INR internet plans, people who recently got access to this world, I always thought that typing smalls stuff on MS-Word and saving it is no big deal,.

Every kid can do it and kids who were my peer could do it but then one day I came across some people who are adults(not kids )from not so blessed background and they requested a staff at some place to let them use the computer so they can learn using it(they were not idiots..just trying hard to get jobs to support their preparation for govt exams).

I could see the sparkle in their eyes when they received permission, MS-Word was like something other from this world and smallest of system errors scared them.

You don't appreciate the ideas of freedom of expression when you are in china/dictatorship, only when you get exposed to such ideas, better say educated about those rights and given the taste of what it is to exercise those rights and what happens when someone breaches them only then you appreciate the ideas of such rights

Same goes for privacy especially in context of digital privacy.

We should try to educate them of their rights with utmost care and sincerity.

You want to teach HTTP vs HTTPS, give a real life example of how it may affect them like let them fill a demo govt service/exam formovver HTTP and then MITM it show how easy it was for you.(and their consequences)

Privacy: It takes nuance, while a person can understand someone they know or a re local to them defacing their privacy they don't get how when their privacy is defaced by Govt/Corporation to affect them, remeber experience is the best teacher, history is only for academics to debate, major of grads in India are BA history they know about Stasi states and its state mass surveillance and so on but when you are so distant from that experience.

We shouldn't brigade over people who are not so technically nuanced, all are trying to make ends meet. We should be like a compassionate teacher with all the patience in the world if want people to appreciate rights fundamental in nature but continusly evolving their form in this fast forward digital world

Are you stupid or what? Governments have been monitoring landline phone calls since World War 1 era.

Dude, India has the second-largest internet users: List Of Countries By Internet Users

Being poor has nothing to do with ignorance.

Indians were always subservient to authority since ancient times, just like the British Era. They conquered India without any war. That only happens with Indians.

@Dark_Nate Is Jio fiber voip also unencrypted like Bsnl ftth voip ?

What's the point of jio having encryption.
Motta bhai can hear us all.
