Parameter
voIpProt.SIP.header.warning.codes.accept
Specify a list of accepted warning codes.
If set to Null, all codes are accepted. Only codes between 300 and 399 are supported.
For example, if you want to accept only codes 325 to 330:
voIpProt.SIP.header.warning.codes.accept=325,326,327,328,329,330
Text will be shown in the appropriate language. For more information, see lcl_ml_lang_menu_x.
voIpProt.SIP.header.warning.enable
If set to 1, the warning header is displayed if received. If set to 0, the warning header is not displayed.
voIpProt.SIP.IM.autoAnswerDelay
The time interval from receipt of the instant message invitation to automatically accepting the invitation.
voIpProt.SIP.keepalive.sessionTimers
If set to 1, the session timer will be enabled. If set to 0, the session timer will be disabled, and the phone will not
declare "timer" in "Support" header in an INVITE. The phone will still respond to a re-INVITE or UPDATE. The
phone will not try to re-INVITE or UPDATE even if the remote endpoint asks for it.
voIpProt.SIP.lcs
If 0, the Microsoft Live Communications Server (LCS) is not supported. If 1, LCS is supported. This parameter
can set for a specific registration using reg.x.lcs.
voIpProt.SIP.lineSeize.retries
Controls the number of times the phone will retry a notify when attempting to seize a line (BLA).
voIpProt.SIP.local.port
The local port for sending and receiving SIP signaling packets.
If set to 0, 5060 is used for the local port but is not advertised in the SIP signaling.
If set to some other value, that value is used for the local port and it is advertised in the SIP signaling.
voIpProt.SIP.ms-forking
If set to 0, support for MS-forking is disabled. If set to 1, support for MS-forking is enabled and the phone will
reject all Instant Message INVITEs. This parameter is applies when installing Microsoft Live Communications
Server.
Note that if any endpoint registered to the same account has MS-forking disabled, all other endpoints default
back to non-forking mode. Windows Messenger does not use MS-forking so be aware of this behavior if one of
the endpoints is using Windows Messenger.
voIpProt.SIP.mtls.enable
If 0, Mutual TLS is disabled. If 1, Mutual TLS is enabled. Used in conjunction with Microsoft Lync 2010.
voIpProt.SIP.musicOnHold.uri
A URI that provides the media stream to play for the remote party on hold. This parameter is used if
reg.x.musicOnHold.uri is Null.
Note: The SIP URI parameter transport is supported when configured with the values of UDP, TCP, or TLS.
