FaxBack NET SatisFAXtion 9.0 - Fax Server Manual - Manual (Page 188)

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 (non­fax) 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 minimum time between dials
across all channels. In effect this limits the calls per­second to 1000 ÷ sip_invite_delay_msecs.
A value of 0 imposes no artificial 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: 20.
sip_retry_invite_delay_msecs [dword 0–1000]: This is the time to wait between
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=T38­FaxMaxBuffer
SDP attribute. Default: 200.
t38_fax_max_datagram [dword 0–65535]: Datagram size to specify in the
a=T38FaxMaxDatagram SDP attribute. Default: 72.
t38_control_redundancy [dword 0–65535]: Levels of redundant data to include in each T.38
“low speed” control packet. Default: 5.
t38_image_redundancy [dword 0–65535]: Levels of redundant data to include 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
