optionTagInRequireHeader
| Use this control to suppress REPLACE tag in the Require header.
If the Replaces header is present in a received SIP REFER request, the SBC includes the contents of the Replaces header (callID, From Tag and To Tag) in the outgoing INVITE without a full ERE query. This enables one SBC to transfer two independent calls and connect them together using IP trunk group (IPTG) routing. IPTG routing must be enabled for this feature. suppressReplaceTag – Controls the content in Require headers to be sent to the peer. When enabled, the REPLACE tag is suppressed in the Require header. If disabled, the REPLACE tag is included in the Require header.
