Despite doing everything correctly, I get the error '*SIP gateway failed to connect call*'. Call ID:

14355851-24b7-4314-bfbf-af53b14a8cbe

As you can see in the picture, I can call for a number by entering the SIP address of Zadarma in Zoiper, but why do I get this error when I call for a number after entering the same information in Vapi? Can you please help me? I don't think there is a problem with Zadarma, there is a problem with Vapi. Thanks. @Vapi @Shubham Bajaj https://cdn.discordapp.com/attachments/1344704688313864325/1344704688783888535/image.png?ex=67c1e155&is=67c08fd5&hm=898a8370676b0690a2810b978a772fce68f298545f6a5b66371676d3c2989404& https://cdn.discordapp.com/attachments/1344704688313864325/1344704689056383059/image.png?ex=67c1e155&is=67c08fd5&hm=8e1e8f69168b8eb38f00a10e157209d273ab402abbdff6446ac54299902e2982&

As you can see in the picture, I have already entered the information correctly. Can you please help me to enter it more accurately or if I have missed something?

@Hamza your correct but this is what I am getting back from the system, let me see what else i can get for you.

Added a documentation around it
