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 rein-

vite 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 be-
tween multiple SIP

INVITES

. This setting serializes all dials and specifies the

minimum time between dials across all channels. In effect this limits the calls-
per-second to 1000 ÷ sip_invite_delay_msecs. A value of 0 imposes no artifi-
cial rate limit and IP_Fax will send calls as fast as possible. Default:

100

sip_retry_invite_count [dword 0–1000]: This is the max number of times to
retry for a when doing the

sip_retry_invite_error_numbers

logic. Default:

sip_retry_invite_delay_msecs [dword 0–1000]: This is the time to wait be-
tween sip_retry_invite_error_numbers retries. Default:

500

sip_retry_invite_error_numbers [string]: Some services return an error if
they are busy and if the

INVITE

is sent again within a short period, it should

succeed. This is a list of the error that and

INVITE

should be repeated for. This

is a list of comma separated IP_FAX error numbers (

not

SIP response codes)

Format: comma separated list of hexadecimal numbers. Default:

28675,28496

start_port_number [dword 1–65535]: First UDP port to allocate for RTP and
T.38. Default:

49152

t38_fax_max_buffer [dword 0–65535]: Buffer size to specify in the

a=T38-

FaxMaxBuffer

SDP attribute. Default:

200

t38_fax_max_datagram [dword 0–65535]: Datagram size to specify in the

a=T38FaxMaxDatagram

SDP attribute. Default:

t38_control_redundancy [dword 0–65535]: Levels of redundant data to in-
clude in each T.38 “low speed” control packet. Default: 5.
t38_image_redundancy [dword 0–65535]: Levels of redundant data to in-
clude in each T.38 “high speed” image packet. Default: 2.
t38_qos_token_rate [dword 0–65535]: TokenRate of sending T.38 RSVP
FlowSpec. Default:

9250

t38_qos_peak_bandwidth [dword 0–65535]: PeakBandwidth of sending
T.38 RSVP FlowSpec. Default:

13875

t38_qos_token_bucket_size [dword 0–65535]: TokenBucketSize of sending
T.38 RSVP FlowSpec. Default:

680

t38_qos_latency [string]: Latency of sending T.38 RSVP FlowSpec. Default:

QOS_NOT_SPECIFIED
