[cisco-voip] SIP Normalization Script

[Roger Wiklund]

Check out the dev guide for SIP transperency and normalization:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/sip_tn/8_5_1/sip_t_n.pdf

page 27, modifyHeader

Here is my Diversion header normalization script, if you wanna use it
as base and modify to your needs, not that this uses the
applyNumberMask function because I modify number and not the IP.

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.
