  • Page 326 Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series/CP860 IP Phones servers. Diversion/History-Info IP phones support the redirected call information sent by the SIP server with Diversion header, per draft-levy-sip-diversion-08, or History-info header, per RFC 4244. The Diversion/History-info header is used to inform the IP phone of a call’s history. For example, when a phone has been set to enable call forward, the Diversion/History-info header allows the receiving phone to indicate who the call was from, and from which phone number it was forwarded.
