SIP, TCP and dialogs

Hello all. Can the LTM be configured (with or without iRules) to allow inbound SIP calls over UDP or TCP to be split into dialogs such that each dialog results in a distinct TCP connection to the servers in a pool? I'm interested in developing a SIP UA that can be implemented using a traditional fork scheme (ie, fork a child, accept SIP/TCP connection, negotiate RTP streams, handle call, exit). Regards, Iker
