Below is the whole exchange in between the two connecting events, the Caller (A) and also the Callee (B), through the Telegram servers (S).

A chooses a random value of a, 1 < a < p-1, and also calculates g_a:=power(g, a) mod p (a 256-byte number) and also g_a_hash:=SHA256(g_a) (32 bytes long). An invokes (sends to web server S) phone. demand, Call, which has the area g_a_hash: bytes, to name a few. For this phone call, this field is to be full of g_a_hash, g_a itself.

This upgrade, in addition to the identification of An and various other pertinent criteria, contains the g_a_hash field, full of the value acquired from A. B accepts the phone call on among their tools, stores the obtained value of g_a_hash for this instance of the voice telephone call creation procedure, picks an arbitrary worth of b, 1 < b < p-1, computes g_b:=power(g, b) mod p, carries out all the needed safety and security checks, and also conjures up the phone.
