The SL4020 supplementary calling features of selective call forwarding, distinctive ring, caller id blocking, and do not disturb require specification of the calling party. There are several places in the SIP invite header that could carry that caller information. The “FROM” header of a SIP Message is as follows: From: CallerId;tag=G1024jh3-NXr3s…… The CallerID field of this header is used in the “Caller ID” fields of supplementary service features. Some implementations identify the callerID as the “Display Name” For example: The “FROM” header of a SIP Message may look like: From: 123;tag=G1024jh3-NXr3s…… To use call forwarding, distinctive ring, caller id blocking and do not disturb specify “123” as the caller id.
