[Serusers] ser and History-Info (RFC 4244) for VM/UM application

hi, does anyone have experience in using ser in processing call-forwarding/redirection signaled in the History-Info section (as per RFC 4244)? the application context is ser as a means to interpolate signaling between an IP PBX and a SIP-speaking VM/UM platform (I3 Communite -- v2.3.1). the problem i am trying to solve (at least in the near-term) is that the PBX is using History-Info to signal call-forwarding events (ex: CFNA, CFB) while Communite is expecting call-forwarding to be signaled via Diversion. until the platforms support have a call-forwarding signaling method in common, i would like to be able to insert ser into the signaling path -- more or less as a translator between the two platforms. tia, john john hess <jhess(a)berkeley.edu> nocman ist, uc berkeley 510 643-6401
