Outbound arbitrary SIP headers

The Blueworx Voice Response APIs can be used to specify headers and header data that are sent in certain outgoing SIP messages. This allows the state table, VXML and CCXML APIs to specify headers and associated values in outbound SIP messages:

Headers and associated values in the following situations on the identified outbound SIP messages:

Outbound call (initial INVITE message)
Blind transfer (REFER message)
Attended transfer (INVITE message used to establish second leg of transfer)
Near end disconnect (BYE message)

As with inbound headers, up to 10 outbound headers can be defined in file

 /usr/lpp/dirTalk/db/sys_dir/voip/siphdrtags.cfg

Duplicates, and any exceeding 10 are ignored. Header entries are treated as defining both inbound and outbound headers. The following standard tags supported by state tables are exempt from this limit of 10 headers, and can always be sent:

TO_HDR, FROM_HDR, REQ_HDR, DIV_HDR, A_LANG_HDR, 
PRIVACY_HDR, PASSID_HDR, RPARTYID_HDR
