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

[Stephen James]

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.

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

nobility must be earned.

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
