Header
Lets you use compact SIP headers in outbound SIP
messages. Select yes or no from the drop-down menu. If

outbound SIP messages. If set to no, the ATA device uses
normal SIP headers. If inbound SIP requests contain
compact headers, ATA device reuses the same compact
headers when generating the response regardless the
