[SIPForum-discussion] Placement of "cic" Field in Request URI

[Gonzalo Gasca]

Hi Heather 
We use cic option quite often in our SP solution, (CTX with Cisco SBC)
Here an example or how we use it:

INVITE sip:18881112000**11111111 at 10.22.132.10:5060;cic=101 SIP/2.0

We normally place it in request URI after user at domain before SIP version as
a uri-parameter
Part of my LUA script to insert it after request URI.

local cicnumber = scriptParameters.getValue("cicnumber")

M = {}
function M.outbound_INVITE(msg)
    local isInitialInvite = msg:isInitialInviteRequest()
    if isInitialInvite and cicnumber
    then
        local method, ruri, ver = msg:getRequestLine()
        local uri = ruri .. ";cic=" .. cicnumber
msg:setRequestUri(uri)
    end
end
return M

Hello,

You have to dial the number and cic value [6245000000002215050] , and cic
value most be configured in the system(SUT),
The URI will be 
sip:+6245000000002215050 at example.com;user=phone

Thanks&Regards,

Life is no brief candle for me. It is a sort of splendid torch, which I have
got hold of for the moment, and I want to make it burn as brightly as
possible before handling it to future generations.
