optionTagInSupportedHeader
| Use this control to suppress the REPLACE tag in the Supported header.
If the Replaces header is present in a received SIP REFER request, the SBC includes the contents of the Supported header (call ID, From Tag and To Tag) in the outgoing INVITE, OPTIONS, and INVITE/OPTIONS 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. This control suppresses this feature. suppressReplaceTag – Controls the content in Supported headers to be sent to the peer. When enabled, the REPLACE tag is suppressed in the Supported header. If disabled, the REPLACE tag is included in the Supported header.
