General Settings

Call from Fax Voip T.38 Modem

You can specify whether the rule should be applied to all, single or several Virtual COM Ports (modems).

From any modem

The rule applies to all Virtual COM Ports (modems).

From selected modems

The rule applies to one or several Virtual COM Ports (modems). Virtual COM Ports for which the rule applies should be selected from the list. Note, that in the case of using Fax Voip driver for Virtual COM Ports, external ports (connected to fax program) are listed in the right panel. In the case of using 3rd party driver for Virtual COM Ports, internal ports (connected to Fax Voip T.38 Modem application) are listed in the right panel.

Outgoing Number Format

These options allow you to apply the rule to all, to single or to group of dialed numbers.

If Number =

Select this option to apply the rule to all dialed numbers or to single dialed number.

Select <any> to apply the rule to all dialed numbers.

Enter the phone number to apply the rule to that number only.

If Number starts with ... and number of digits =

The rule applies to numbers with specified prefix and (or) to numbers of specified length.

Dial on Number

These options allow you to transform the dialed number to the required format if necessary.

Dial on Number =

Use this option if you want to route calls without changing the dialed number, or if you want to route all calls to the specified number.

Select <NUM> to route calls without changing the dialed number.

Enter the phone number to route all calls to that number.

Remove digits ... Prepend...

Use this option if you want to add a specified prefix to the dialed number and (or) remove the first few digits or other characters (1-9) in the number being dialed. When applying Remove digits option to original dialed number that contains characters other than digits, the behavior can be unpredictable (with some special characters). It is recommended to test before using.

Direct call to IP

Use this option to be possible to do direct call to IP. For example, call to number '12345*192*168*0*2*5065' will be routed to 192.168.0.2:5065 to number 12345. When selecting this option, no need to enter the address of SIP (or H.323) server in the Dial on SIP Sever (Route to address) field.

Dial on Line

The settings, specified in this area, allow you to route call to the specified SIP or H.323 endpoint or via ISDN CAPI 2.0 line. These settings also allow you to bind a call to a specific SIP Registration or route call via H.323 Gatekeeper. In the case of ISDN CAPI 2.0, you can bind a call to a specific ISDN controller and (or) B-channel.

VOIP Protocol

SIP

Select this option if you want to route calls using SIP protocol.

 

Transport

If this field you can select transport for outgoing SIP calls. Select SIP over UDP to use UDP. Select SIP over TCP to use TCP. Select SIP over TLS to use TLS. By default UDP is used. If Default Outbound Proxy is used (see in the Outbound Proxy Settings), the transport specified in proxy settings will be used. If individual proxy is specified in the Use Outbound Proxy field, SIP over UDP will be used. Note that TCP and TLS can be not supported by your server.

Tel URI scheme

If this option is selected, Fax Voip T.38 Modem will use Tel URI scheme in an outgoing SIP calls. Tel URI scheme can be used with SIP over UDP and SIP over TCP. The SIP INVITE message will be sent in the following format:

SIP/SDP Request: INVITE tel:+13601234567;phone-context=multitel.com, with session description

If this option is not selected, SIP INVITE message will be sent in standard format:

SIP/SDP Request: INVITE sip:[email protected], with session description

Note that in the case of using Tel URI scheme you are not able to specify remote port in the Dial on SIP Server field. You should also understand that not every SIP server is able to operate under Tel URI scheme and should not use this option without need. On the other hand, as we know, some servers require the use of Tel URI scheme. And that's why we added this option.

sips:

This option can be used with only SIP over TLS. If this option is selected, Fax Voip T.38 Modem will use sips: prefix instead of standard sip: prefix.

Dial on SIP Server

Name or IP-address of SIP endpoint or SIP server to which the call will be routed. Usually coincide with the SIP Registrar Server of one of the SIP Registrations. If there are entries in SIP Registrations table, the server name can be selected from the drop-down list. Note that in the case of using Tel URI scheme you are not able to specify remote port in this field.

Use Outbound Proxy

Address of SIP Outbound Proxy, which is used for Outgoing Calls. It is strongly recommended  to use the same Outbound Proxy for both SIP Registration and Outgoing Calls via this registration. This option overrides the Default Outbound Proxy, specified in the Outbound Proxy Settings. If Outbound Proxy is specified in this field, Fax Voip T.38 Modem always uses SIP over UDP when doing outgoing calls. To use proxy with TCP or TLS transport,  should use Default Outbound Proxy settings (see in the Outbound Proxy Settings).

Username

Username (SIP-ID) that will be used with the rule. Usually coincide with the Username (or SIP-ID) of one of the SIP Registrations. Digital Username usually displayed at other side as NUMBER part of Caller ID. If there are entries in the SIP Registrations table with the SIP Server specified in the Dial on SIP Server field, the Username can be selected from the drop-down list.

Use default

To modify Username field, uncheck this option. If this option is checked, Fax Voip T.38 Modem will use either the Username from the first entry in the SIP Registration table with the SIP Server specified in the Dial on SIP Server field, or the default SIP Username, specified in the SIP Settings.

Display Name

Name you would like to be reported to other users. Display Name usually displayed at other side as the NAME part of Caller ID. This option overrides the default Display Name, specified in the VOIP Settings.

Use default

To modify Display Name field, uncheck this option. If this option is checked, the default Display Name is used.

Depending on the values, specified in the Dial on SIP Server and Username fields and some other Fax Voip T.38 Modem parameters the behavior of the outgoing call can be different:

Case 1:

1.     Dial on SIP Server = 'sip.server.com'

2.     Username = '*<default>'

3.     There is at least 1 entry in the SIP Registration table with

username@registrar = '<name1>@ sip.server.com', where <name1> - any name.

The call will be routed using the first SIP Registration for specified server.

Case 2:

1.     Dial on SIP Server = 'sip.server.com'

2.     Username = 'NAME'

3.     There is a record in the SIP Registration table with

username@registrar = '[email protected]'.

The call will be routed via SIP Registration entry '[email protected]'.

Case 3:

1.     Dial on SIP Server = 'sip.server.com'

2.     Username = 'NAME'

3.     The server name is the same as the name of default proxy server (see in the Outbound Proxy Settings). The Username is the same as the Proxy Username. Use default Outbound Proxy option is checked.

The call will be routed to default Proxy. The username and password specified in the proxy settings can be used for authantication.

Case 4:

1.     To SIP Line = 'sip.server.com'

2.     Username = '*<default>'

3.     There are no SIP Registration with

username@registrar = '<name>@sip.server.com', where <name> - any name.

The call will be routed to sip.server.com with default SIP Username, specified in the SIP Settings (usually FaxVoip). This method can be used if authantication is not required.

Case 5:

1.     To SIP Line = 'sip.server.com'

2.     Username = 'NAME'

3.     There are no SIP Registrations with

username@registrar = '[email protected]'.

The call will be routed to sip.server.com with username NAME. This method can be used if authantication is not required. Digital NAME usually displayed at other side as NUMBER part of Caller ID.

H.323

Select this option if you want to route calls using H.323 protocol.

Route to address

Name or IP-address of H.323 endpoint to which the call will be routed. If the registration with H.323 Gatekeeper is used, should understand that outgoing H.323 calls to arbitrary IP addresses may be prohibited by the Gatekeeper policy.

Route calls to Gatekeeper

Use this option to route calls via H.323 Gatekeeper.

Username

Username that will be used with the rule. This parameter allows to override the default Caller ID Number.

Use default

To modify Username field, uncheck this option. If this option is checked, the top number from the Telephone numbers list (see in the H.323 settings) will be recognized by remote party as Caller ID Number.

Display Name

Name you would like to be reported to other users. Display Name usually displayed at other side as the Caller ID Name. This option overrides the default Display Name, specified in the VOIP Settings.

Use default

To modify Display Name field, uncheck this option. If this option is checked, the default Display Name is used.

ISDN CAPI 2.0

Select this option if you want to route calls via ISDN CAPI 2.0 line.

Username

Username (ISDN number) that will be used with the rule. This parameter allows to override the default Caller ID Number. Username consisting of letters is ignored, so digits should be used to include CallerID in the CAPI 2.0 message. Depending on the properties of your ISDN card, CallerID can be ignored and overridden. If you enter an incorrect ISDN number that does not satisfy your ISDN settings, the outgoing call can be rejected. Note that when using username consisting of letters, such error is not possible.

Use default

To modify Username field, uncheck this option. If this option is checked, Fax Voip T.38 Modem will use the ISDN Username (number), specified in the ISDN CAPI 2.0 Settings.
