Airtel Mobile now billing VoIP Calls separately on Cellular Networks?

[talyan]

Does this move affect instant messenger services without Voice/video calling support. E.g Telegram,Hike?.

I don't think so.

Just voip calls. Video calls are free for now I think.

Airtel will use Deep Packet Inspection technology to look for VOIP data.

Exactly, there is no way to detect unless they sniff the packets, which would be violation of user privacy.

TRAI however does not understand this point. (or unwilling to use it on purpose?!)

They are going to look for one of this:

List of SIP request methods - Wikipedia, the free encyclopedia
List of SIP response codes - Wikipedia, the free encyclopedia

Once they see "INVITE" or "180 Ringing", they will treat connection as VoIP.

Are all these apps are not using https port.facebook messenger uses https port then how they will identify data.अँधेरे में तीर चला रहा है लगता है।

if they use https and default port 443 then i dont think ISPs can do anything about it.but i guess either they dont use https so ISPs can scan packets or they are using a different port of Voip.

Voips calls(voice and video) travel through a dedicated port.

Here is my confusion.

I'm assuming a call made from my skype app(samsung phone) to a landline phone in germany uses a dedicated voip port. Thik hai. Airtel computers can spot this and impose standard charges.

But what about a call that does not involve a landline/mobile number?

Examples: calls between:

computer(skype soft) to phone (skype app)
computer to computer
phone app to phone app

Skype does not use single port. Skype uses ANY RANDOM port. (above 1024)

Microsoft support question:
Which ports need to be open to use Skype for Windows desktop?

When you install Skype, a port above 1024 is chosen at random as the port for incoming connections
