sip_max_forwards [dword 0–256]: Specifies the value that the IP fax driver
will set for the Max-Forwards: field in SIP messages that it sends. Default:

sip_sdp_username [string]: The name to use in the

owner attribute in the

SDP. Default:

IPFax

sip_proxy [string]: The IP address or host name to use as a SIP proxy.

sip_proxy_password [string]: If the SIP proxy challenges for authentication,
use this password.

sip_proxy_user_name [string]: If the SIP proxy challenges for authentication,
use this user name.

sip_registrar [string]: The IP address or host name to

with (the

“registrar”).

sip_registrar_aor [string]: The AoR to use for the

message. Typically

set to the same as the user name.

sip_registrar_password [string]: The password to use for the

message.

sip_registrar_refresh_seconds [dword 0–65535]: When registration is
enabled, refresh the registration after this many seconds. If set to zero, the
refresh is sent after 80% of the registrar’s “expires” response. If the registrar
does not specify an “expires”, then the registration is refreshed every 60
seconds.

sip_registrar_user_name [string]: The user name to use for the

message.

sip_remote_ip_address [string]: Specifies the IP address, and optionally
port number, of the T38 router/gateway that the IP fax driver will use when
sending faxes. The router/gateway must support SIP 2.0 over UDP. If an IP
address is provided without a port number, for example,

10.0.0.15

, then the IP

fax driver will use a port number of 5060. To provide an alternate port number,
append a colon (

) then port number to the IP address, for example,

10.0.0.15:5061

sip_mode [string]: This governs alternate behaviors for IP_FAX initial

INVITE

Format: Comma separated list of the following:

T38_INVITE

– Outbound initial

INVITE

will specify both G.711 µ-law

and T.38 in its SDP.

G729

– Outbound initial

INVITE

will specify G.729 as the only media.

Cannot be used with any other setting.

USE_DIVERSION_AS_DNIS

– Uses the SIP “Diversion:” header as DID

instead of the request URI.

USE_TO_AS_DNIS

– Uses the SIP “To:” header as DID instead of the

request URI.

T38_ORIGINATE_REINVITE

– On an outbound call, initiate the reinvite

to T.38 on the fax server side rather than waiting for the media
gateway. Note that this will alter the error codes generated when
calling voice (non-fax) numbers.

GATEWAY

– Not used.

PROXY

– Not used.

REGISTRAR

– Not used.

sip_invite_delay_msecs [dword 0–30000]: This is the min time to delay
between multiple SIP

INVITES

. This setting serializes all dials and specifies the
