While looking at the traces i noticed that there is *wild space* in FROM header between *u...@domain* part of intial invite. And because of this whenever UAS is sending 100 trying with same space then my SBC is unable to understand that provisional resposne to reset the timer and hence its keep sending the invite to termination side on leg 2.

A space is not allowed at that location (see RFC 3261 section 25.1 for the BNF). - There are two '#' characters in the user of the request-URI of the request line. '#' is not allowed directly in the user of a URI, it must be represented as '%23', as in : INVITE sip:%2308864%[email protected]<mailto:[email protected]> SIP/2.0 - There is no User-Agent header describing the UAC that generated this INVITE, so it is difficult to know to whom to send a problem report. I suggest that you correct or replace the UAC.
