How to configure ONT for VoIP softphone on Airtel Xstream Broadband?

Does this mean that (as I've mailed airtel for changing settings for VoIP ) VoIP is a part of my package and they can't deny it. Rather it is landline or soft phone
 
hey yo @tr1k0N4 .. i was trying to unlock this ont. but when was entering password. on multiple attempts it says request closed by foreign host. who is foreign host? A!rtel?
I am anxious rn. will a!rtel call me for tempering with ont?
 
can you help me in unlocking this. even if i dont know password to login i know how to revert this process. on another thread , i found bootcfg customer DASAN replace DASAN with A1rtel ( typo)
