Attribute

Values

Default

Interpretation

 

 

 

 

voIpProt.SIP.useContactInReferTo

0, 1

0

If set to 0, the “To URI” is used in the REFER.

 

 

 

If set to 1, the “Contact URI” is used in the

 

 

 

REFER.

 

 

 

 

voIpProt.SIP.useRFC2543hold

0, 1

0

If set to 1, use the obsolete c=0.0.0.0

 

 

 

RFC2543 technique, otherwise, use SDP

 

 

 

media direction attributes (such as

 

 

 

a=sendonly) per RFC 3264 when initiating

 

 

 

hold. In either case, the phone processes

 

 

 

incoming hold signaling in either format.

 

 

 

 

voIpProt.SIP.useSendonlyHold

0, 1

1

If set to 1, the phone will send a reinvite with

 

 

 

a stream mode attribute of “sendonly” when a

 

 

 

call is put on hold. This is the same as the

 

 

 

previous behavior.

 

 

 

If set to 0, the phone will send a reinvite with

 

 

 

a stream mode attribute of “inactive” when a

 

 

 

call is put on hold.

 

 

 

NOTE: The phone will ignore the value of this

 

 

 

parameter if set to 1 when the parameter

 

 

 

voIpProt.SIP.useRFC2543hold is also set

 

 

 

to 1 (default is 0).

 

 

 

 

voIpProt.SIP.lcs

0, 1

0

If set to 1, the proprietary “epid” parameter is

 

 

 

added to the From field of all requests to

 

 

 

support Microsoft Live Communications

 

 

 

Server.

 

 

 

 

voIpProt.SIP.ms-forking

0, 1

0

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 relevant for

 

 

 

Microsoft Live Communications Server

 

 

 

server installations.

 

 

 

Note that if any end point registered to the

 

 

 

same account has MS-forking disabled, all

 

 

 

other end points default back to non-forking

 

 

 

mode. Windows Messenger does not use

 

 

 

MS-forking so be aware of this behavior if

 

 

 

one of the end points is Windows Messenger.

 

 

 

 

voIpProt.SIP.dialog.usePvalue

0, 1

0

If set to 0, phone uses "pval" field name in

 

 

 

Dialog. This obeys the

 

 

 

draft-ietf-sipping-dialog-package-06.txt draft.

 

 

 

If set to 1, phone uses a field name of

 

 

 

"pvalue".
