Lua Script Remote-Party-ID

nikhilrajan — Thu, 17 Nov 2016 10:54:32 GMT

Hi All,

I need to modify this script to change this header. Can any one pls help me on this.

Remote-Party-ID "London Test" ;party=calling;screen=yes;privacy=off

Remote-Party-ID "London Test" ;party=calling;screen=yes;privacy=full

The script is

M = {}

function M.outbound_INVITE(msg)

local fromtag = msg:getHeaderValueParameter("From", "tag")

local pai = msg:getHeader("P-Asserted-Identity")

local uri = string.match(pai, "(<sip:%+4420.+>)")

local uri2 = string.match(pai, "(<sip:%+441785.+>)")

if uri or uri2

then

msg:modifyHeader("From", "Anonymous <sip:anonymous@anonymous.invalid>")

msg:addHeaderValueParameter("From", "tag", fromtag)

msg:addHeader("Privacy", "id")

end

return M

I tried applying below but it failed.

function M.outbound_INVITE(msg)

local remote = msg:getHeader("Remote-Party-ID")

local privacy = string.find(remote, "off")

local target = string.sub(remote, privacy)

local replace = string.gsub(target, "full")

msg:modifyHeader("Remote-Party-ID", replace)

end

return M

Can anyone pls help me on this?

Regards,

Nikhil

It would be easier if you don't try to use the indexes returned by string.find:

local remote = msg:getHeader("Remote-Party-ID")

local replace = string.gsub(remote, "privacy=off", "privacy=full")

msg:modifyHeader("Remote-Party-ID", replace)
