General Settings

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

The rule applies to numbers with specified prefix.

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.

Dial on Line

The settings, specified in this area, allow you to route call to the specified SIP or H.323 endpoint. These settings also allow you to bind a call to a specific SIP Registration or route call via H.323 Gatekeeper.

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. 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 can be not supported by your server.

Tel URI scheme

If this option is selected, Fax Voip FSP 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:13601234567@sipserver.com, 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.

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 FSP always uses SIP over UDP when doing outgoing calls. To use proxy with TCP 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 FSP 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 SIP Display Name, specified in the SIP Settings.

Use default

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

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

Case 1:
