Parameter
voIpProt.SIP.conference.parallelRefer
If 1, a parallel REFER is sent to the call server. Note: This parameter must be set for Siemens Openscape
Centralized Conferencing.
voIpProt.SIP.connectionReuse.useAlias
If set to 0, the alias parameter is not added to the via header
If set to 1, the phone uses the connection reuse draft which introduces "alias".
voIpProt.SIP.csta
If 0, the uaCSTA (User Agent Computer Supported Telecommunications Applications) feature is disabled. If 1,

voIpProt.SIP.dialog.strictXLineID
If 0, the phone will not look for x-line-id (call appearance indec) in a SIP INVITE message, if one is not present.
Instead, when it receives INVITE, the phone will generate the call appearance locally and pass that information
to other parties involved in the call.
voIpProt.SIP.dialog.usePvalue
If set to 0, phone uses a pval field name in Dialog. This obeys the draft-ietf-sipping-dialog-package-06.txt draft.
If set to 1, the phone uses a field name of pvalue.
