exact four digits. If you are getting ten digits from a PRI, enter those exact ten
digits.
When troubleshooting DID routing, remember that any fax that is not routed
will be sent to the Postmaster user. Check there, and look for the

DID

column,

that will show the exact digits NET SatisFAXtion received. If that column is
blank, then no DID digits were received.

DTMF

DTMF routing is used when the fax server’s analog fax device phone lines are
connected to a PBX, and the PBX is capable of generating DTMF tones.
DTMF (Dual Tone Multi Frequency) tones are also called touch tones. They are
the same tones that are used to dial the destination phone number when you
call out on an analog telephone. Only in this case, they are generated by a PBX
to relay to the fax server what the called number is, to allow DID routing.
With standard analog phone lines it is not possible to tell what number the call-
er dialed. Therefore some other mechanism must be employed to communicate
that called number to the fax server. In this case, when the fax server answers
a call it listens for a few seconds for DTMF tones. These tones are usually gen-
erated at that point by a PBX.
By default, a modem will not collect DTMF tones from the PBX. It is necessary
to run the

DTMF Setup

program to enable them to collect digits.

DTMF routing is not the same as DID, CallerID or ANI. While DID numbers can
be routed from your phone switch, PBX or CO, they must be translated into
DTMF tones that are passed to the modem when it answers. To test that
DTMF is available on the line, connect an analog telephone to one of the phone
lines that will be used for the fax server. Call a DID number. When that phone
rings, answer it and listen for DTMF tones to be played back. If you do not hear
the DTMF tones, work with your phone switch or phone vendor to get this
working first.

Strip Digits from Front or Back of DID

With some PBXs or VoIP systems, there are more digits provided in the DID
than are desired.
When using

AudioCodes

equipment, see

Protocol Configuration Manipulation

Tables

in the web interface of the AudioCodes device.

To strip a fixed length of digits from the front (left) of a number, set the fol-
lowing registry key. Note that in Administration and Reports the full string will
still be visible, but this many digits will be ignored for routing purposes.

[HKEY_LOCAL_MACHINE\SOFTWARE\FaxBack\CASDrive]

"DtmfRouteStripCount" = <NumberToStrip>

To strip digits from the end (right) of a number, configure the number of DTMF
digits collected to be less than the full digit string being sent from the PBX.
