If you are on 8.6.2 you have a Transformation CSS for Diversion header
on the SIP trunk.
If you are on 8.5 you can use SIP normalization script for Diversion header.

Sample script:

M = {}
local mask = scriptParameters.getValue(“Diversion-Mask”)
 function mask_diversion(msg)
    if mask
    then
      msg:applyNumberMask(“Diversion”, mask)
    end
end
function M.outbound_INVITE(msg)
mask_diversion(msg)
end
return M

It defines a “variable” called Diversion-Mask.

Under the SIP trunk config, select your script, and enter
Diversion-Mask in the Parameter Name
In the Parameter Value enter your mask, for example if 4685661XXXX.

I prefer to normalize digits/headers on the SIP-trunk in outbound
direction. If that's not possible, do it in the CUBE like Bill
suggested.
I'm in the process of writing what I think is optimal Verizon
SIP-trunk design with multi countries with CUBE, extension mobility,
TEHO etc.
