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

Thu May 31 18:11:51 UTC 2012

Dear Gonzalo,
unfortunately your way to use the cic is not correct. The cic is a Tel URI 
parameter (defined in rfc4694 - http://tools.ietf.org/html/rfc4694) and it 
has to be placed in front of the @.
I don't want to repeat what Stephen already said . He is totally right.

>RFC 4694 defines the cic parameter as a tel URI parameter. Per 3261 when 
converting from tel URI to sip URI all tel URI parameters become userinfo 
parameters.
>Note, the user=phone parameter indicates that this is a sip URI derived 
from a tel URI.

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

The unfortunate thing is, that all simple SIP implementations out there do 
not support TEL URI parameters - you are lucky, when they can handle the 
SIP parameters in a correct way.

Mit freundlichen Grüßen / Kind regards

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.

Section 4. of 4694 provides the cic parameter.
Section 19.1.6 of 3261 details the conversion from tel to sip

tel:62450000000022;cic=+15050 

becomes

sip:62450000000022;cic=+15050 at example.com;user=phone

I can’t find anything in any RFC’s stating if it is ok for the placement 
of a CIC code to be placed like so:

sip:62450000000022;cic=+15050 at 172.24.165.80:5060;user=phone;transport=udp

We are interoperating with a vendor that states it is in the wrong spot 
but I have found several examples where other vendors have it in the same 
place.

Thanks,

Heather
