Bsnl Provided with this info:
SIP domain : mp.ftth.ims.bsnl.in , Vlan - 1849 only. Not this info outbound proxy, Ip address, default gateway, subnet and Dns like seen in other threads.

These are images of my configuration .
I have wired only Ont of Lb-link and TP-Link access Point.

Help me out, or tell me if it's hopeless, i followed tutorials but didn't understand the reasoning behind.

Voip configuration images, static routing image and voice setting images.

I tried both DHCP and static method, DHCP generate following info IP address , gateway, subnet and dns.

Static route settings.

Hey from what i can see here You have successfully configured the wan and you are able to register your number for voip since in last image its saying i up, now to clear your queries we will get to know what you configured earlier better

1- bsnl will allow only 1 simultaneous connection to voip in any ftth plan aka you can only connect 1 softphone or hardware phone to bsnl at a time

2- the settings you configured for voip in your router is for hardware phone which you can connect to tel port in your router.

now for setting up a soft phone first delete the config on 2nd last pic dont delete the wan profile

and follow the steps i have written in my blog, Here, its for jharkhand but the steps will be same (I was also confused at 1st so decided to write a post about it)

if you have any more questions feel free to ask here
 
Hi, I have read your article and followed the steps but I still can't get VoIP working. I am using Zoiper on Android and the error message is "Registration failed. Request Timeout (408)".

This is my ONT settings:

OHtmoXE.webp


This is the static route I set:

hYhYyJx.webp


These are the settings on Zoiper/Android:

AziWAIG.webp

I tried Mizudroid and Yate.

Mizudroid says: Register rejected. Forbidden.

Yate says:
Code:
SIP/2.0 403 Forbidden
Warning: 399 [some numbers and letters].ims.bsnl.in "Invalid User"


I am using the following:

username: +91<no lead zero STD CODE><8 digit phone number>
password: ftth@<last 4 digits of phone number>

@local_testnet I was successful in setting up voip softphone in zoiper using ONT as router.
Currently i'm using ONT in bridge but VOip not working in bridge mode with same settings.
What could be done to make it work in bridge mode?
 
@bnee that depends on your 2nd router have you made the same settings in your bridged router too ?? and what os it running on i have used openwrt and it works rock solid , another thing can you check if you have any lan bindings or not it might cause issuer other than that without some screenshots or error codes i cannot help you with guesses
 
Is BSNL providing Websocket URL along with the SIP account which includes the domain, username and password?
