Hi,
I am trying to remove all the video lines from an invite that is sent out via a sip trunk in cucm.
Here is my script
Before outbound SIP Normalization msg is:

The script is the following
--------------------------------------
M = {}
function M.outbound_INVITE(msg)
local sdp = msg:getSdp()
if sdp
then
local video = {}
for i=2,4 do
video[i] = sdp:getMediaDescription(i)
if video[i]
then
--remove the video media description
sdp = sdp:removeMediaDescription(i)
--set the modified sdp
msg:setSdp(sdp)
end
end
end
end
return M
---------------------------------------
Can somebody tell me what is wrong with the script ?
The output of the cucm does not make sense to me
