Hi, I have been an user of SIP for a while, but never got into the need to extend it. I have tried to do an extensive research to see if there are any draft or RFC that handles the requirements that I am requested to do. Here is the scenario that I am trying to fulfill.
A UA (custom hardware/software) wants to place or change the call into a secure call. It notifies the other participant by an INVITE or NOTIFY and both UA agree on the change and the details of the security. There are several different method of securing the call, and that would be included in the parameter passed between the UA. If this is not possible is there a way to embed the parameters into the header of the INVITE or NOTIFY so at least both UA know of the request? There are a few phones on the market today some using SKINNY and others using SIP, but it appears that it is being done outside of the SIP traffic. If anyone can either tell me which draft or RFC to look at; that I missed. If this does not exist, is there others out there that are interested in this type of change to SIP; that would like to discuss it?
