header will be omitted so that it can be selected by the negotiation
mechanism. The default setting is "Omit".
UAS Specify Refresher
Specifies which party will refresh the active session if the phone receives
inbound calls. If it is set to “UAC”, the remote party will refresh the active
session. If it is set to “UAS” and the remote party does not support refresh
