At the outset, the problem title suggests that:

(I) The solution may be related to how a telephone works.

(II) The author wishes to share some personal contact detail(s)
through the encrypted message.

Going back to (I), we observe that the numbers 2 through 9 in a
telephone keypad represents the following letters:

Number           Letter
2                  A, B, C
3                  D, E, F
4                  G, H, I
5                  J, K, L
6                  M, N, O
7                  P, Q, R, S
8                  T, U, V
9                  W, X, Y, Z

The numbers 0 and 1 do not represent anything, and so any one of these these can be taken to represent one blank space.

Thus, the given code can be further broken down into:

69 6263 47 584....

Thus, we have some possibilities of three word strings for "69 6263 47" , of which only "my name is" satisfies the contact details criterion in terms of (II).

Now, we know that the author's name is Juggler, and sure enough, the string "jug" is represented by 584

It is now trivial to obsertve that the string "gler" (represented by
"4537") must be affixed to the string "jug" to spell out the author's
name.

Consequently, the required next four digits are 4537.
