To line route, run the Administration program and log in. Go to the User Administration section using
the View ⇨ User Administration menu. Select the user or group you wish to route to, rightclick on it
and select Modify User or Modify Group. Change to the Routing tab. In the Line box, select the line(s)
you wish to route to this user or group. Click OK. Note that if the line is already assigned to a different

2.5.1.3DID/DTMF/DNISRouting
The most flexible routing method is based on the dialed number. This is the actual number that the
sender dialed, which gets relayed through the phone system to the fax server. This means that each
user and group in the system can have its own individual phone number if you choose. Depending on
the telephony technology used the called number has a variety of names. This manual calls this number
a Direct Inward Dial number (DID number). When using a T1/PRI or VoIP provider, Dialed Number
IdentificationSystem(DNIS)isoftenused
.
T1, PRI and VoIP providers will usually deliver DNIS digits with no additional configuration needed in NET
SatisFAXtion. Analog devices on the other hand must use DTMF relay which need configuration on both
ends of the phone line, on the PBX / telco side as well as the NET SatisFAXtion side. See the DTMF
headingbelow.
To DID route, run the Administration program and log in. Go to the User Administration section using
the View ⇨ User Administration menu. Select the user or group you wish to route to, rightclick on it
and select Modify User or Modify Group. Change to the Routing tab. In the Identifier box, enter the digit
string you wish to route to this user or group. In order to route, the Identifier string must match
exactly. If you are getting four digits from a PBX, enter those exact four digits. If you are getting ten
digitsfromaPRI,enterthoseexacttendigits.
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

DTMF
DTMF routing is used when the fax server’s analog fax device phone lines are connected to a
PBX,andthePBXiscapableofgeneratingDTMFtones.
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,toallowDIDrouting.
With standard analog phone lines it is not possible to tell what number the caller 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.ThesetonesareusuallygeneratedatthatpointbyaPBX.
By default, a modem will not collect DTMF tones from the PBX. It is necessary to run the DTMF
Setupprogramtoenablethemtocollectdigits.
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

To strip a fixed length of digits from the front (left) of a number, set the following registry key.
