I just change some settings told by sloj in his post-https://broadband.forum/t/203538/

1. Voice to voice internet (on Huawei modem it is disabled so I use to inspect element on the browser and enable via edit attribute) Screenshot (14).webp
2. Enable NAT
3. Created Static route
4. Setup the Microsip like you guys did see in the attachment

before that I use Primary SIP address, So I was able to receive calls but can't call anyone, and so figure it out accidentally when I put the Standby proxy server address in the Proxy box of microsip.

For Lucknow the upstream servers are at 10.232.133.130 and 10.232.134.130, and the sip password is the same as mentioned previously. These servers dont accept an expire time less than 3600 seconds. I had to setup a sip 'Options' request every 30 seconds to keep the connection alive.

Ya, that is the issue. I can call okay for the first time after starting zoiper or any other app. It's a Symmetric NAT issue from what I found searching the web. Restarting the app or waiting for the registration period to expire and register again fixes it. If you call instantly after the first call, there will be one way audio issue. YATE and MicroSIP have implemented methods to overcome this but other apps haven't.
