This video discusses and illustrates the use of DTMF post code dialing with RightFax and the SR140.

Hello my name is Jay Campbell with The Fax Guys for RightFax University. Today we will walk you through the steps to configure your Dialogic Brooktrout SR140 VOIP fax solution to use DTMF post code routing commands. This video was recorded at 1280 by 720 resolution for High Definition and is best viewed in full screen mode.

In RightFax, certain dialing codes may be required in order to send out from the SR140 (or OEM) fax board using FoIP through a PBX or other telephony device in order to validate/authenticate the call. These codes are typically done using DTMF Post Dialing.

To use DTMF Post Dialing:

For in-band Fax over IP calls using SR140, you can include an ampersand (&) in the dialing rule to initiate post-dialing. The ampersand indicates the beginning of a sequence of DTMF digits to be dialed as soon as the SR140 receives a SIP response code, such as SIP 183 or SIP 200, or a H323 message from the gateway.

You can include all dialing characters for PSTN Telephony in the post-dial string, except 'p', 't', 'w', and '!'. If you include another ampersand (&), processing of the string will be terminated.

the pound key # is also supported.

Let's take a look at the following example:

"@", where:

"@" is the gateway’s IP address.

"&" tells the SR140 to post-dial the digits 999 as soon as one of the following has been received from the gateway: a SIP 183, SIP 200, or H.323 message.

"999" are the digits dialed after the SR140 has received one of the above response codes or messages.

Commas may need to be added between the ampersand and the digits to adjust for delay.

Example: "@,,5555"

In addition, post-dialing must be enabled on the SR140 via the "post_dialing_enable" parameter within the BTCall.cfg and given a value of 1 (to enable) or 0 (to disable).
To do this, browse to .RightFaxDocTransportBrooktrout and open the BTCall.cfg using a text editor (i.e. Notepad). Scroll to the bottom of the list of parameters and enter: post_dialing_enable 1 (single space between enable and 1).

If this parameter is present but un-needed, change this parameter to: post_dialing_enable 0 (single space between enable and 0).

Save this file.

And now you can stop and restart the DocTransport module and test.

That wraps up configuring DTMF post codes for use with the SR140.

This is Jay Campbell with The Fax Guys for RightFax University saying thank you for watching.
