From: "Sunil Kumar Verma" <[EMAIL PROTECTED]> In case of BBUA, is it possible for proxy to generate 1xx response for an INVITE, before receiving any reply from terminating SIP client.
For Ex. SIP client A calling another SIP client B, and before receiving any reply from the SIP client B for the initial INVITE, can proxy generate 180 RINIGING reply? A proxy actually can generate a 180 response. (In principle, it forks the request to an internal UA which generates the 180.) The to-tag on the response will be different from the to-tags of any responses from "real" destinations, so it will create a separate early dialog. That may suffice for your purposes.
