The fields below become available depending upon your selection.

Filter connections by type.

• Select Any to display connections regardless of their type.

• Select Generic to display connections that transport other services such as conferencing, IPTV and the like.

Filter connections by a node.

• Select Any to display connections regardless of the node that is used to transport the traffic.
• Select Node name to display connections that transport traffic via this node.

Filter connections by the tariff that the vendor charges you for transporting a service via this connection.

• Select Any to display connections regardless of the tariff.
• Select Tariff name to display connections that have this tariff.

Filter connections by their status.

• Select Any to display connections regardless of their status.
• Select Yes to display connections that participate in routing.
• Select No to display connections that do not appear on routing lists and are used only for billing purposes.

A connection is a point of change of network ownership, defined as a set of physical and logical parameters, such as IP address, port, etc. It is used to either transport or deliver a service from or to your network. It has a tariff that defines the termination cost, i.e., the price that a vendor charges you.

To create a new connection, fill in the connection details and click Save.

To create a new connection and add another one, click Save & Add another.

Type in a logical description for the connection.

Choose the type of service that this connection transports.

The following fields may differ depending on the type of service that you choose.

Choose the connection type. This defines how the service between your vendor’s gateway and PortaBilling is transported:

• Select SIP to transport calls or messages via the SIP protocol enabled by default.
• Select PSTN to transport calls via a PSTN trunk. This must be enabled on the configuration server.
• Select H323 to transport calls via the H323 protocol. This must be enabled on the configuration server.
• Select SMPP to transport messages via the SMPP protocol enabled by default.

Choose whether the service is transported from your network or delivered to your network via this connection:

• Select To vendor to send traffic from your network to your vendor’s network.
• Select From vendor to receive traffic from your vendor’s network (e.g., calls to DID or toll-free numbers).

Choose a tariff that a vendor charges you for transporting a service via this connection.

The Active status shows whether a connection participates in routing. Connections to voice calls and messaging services are active by default. To exclude a connection from the routing process, disable it. In this case, the connection does not appear on routing lists and is used only for billing purposes.

The Internal status shows that a connection is used to transport services within your network. Enable to create internal connections for your internal (virtual) vendor.

It is disabled by default. This means that this connection is used to transport services to external networks. It requires the following parameters to be set:

Choose how the system identifies a remote gateway.

• Select IP to identify a remote gateway by its IP address.
• Select Gateway ID to identify a remote gateway by its domain name or custom name.
• Select Gateway ID/IP to identify a remote gateway by both its domain or custom name and its IP address.

One or another of the fields below become available depending upon your selection.

Choose the intended use for this connection:

• Select Route to internally registered SIP accounts (SIP-UA) to transport calls/messages among your end users.
• Select SIP-to-Extrenal SIP proxy (SIP-URI) to transport calls/messages directly to an external SIP proxy.
• Select Unified messaging service (INTERNAL) to provide unified messaging services for your end users.

Type in the IP address of the remote gateway (e.g., 23.45.67.89). When this field is empty, calls going to any IP address (not explicitly defined in another connection) will be regarded as going via this connection.

Type in which port to connect to on the remote end. The default port for the chosen protocol (5060 for SIP, 1720 for H.323 protocols set) is used when no value is provided.

This option appears if you choose SMPP in the Type of connections dropdown list. To grant access to the network according to the service policy, select the service policy for this connection.

Choose the protocol to be used to send data to the remote gateway:

• Select UDP to use the User Datagram Protocol. This protocol is used by default.
• Select TCP to use the Transmission Control Protocol.

A distinctive name for the remote gateway. This is used when it is not possible to determine the identity of the remote party (and thus the connection/vendor that the call goes to) by its IP address alone. This ID will then be used to identify the connection, based on additional information available in the accounting record.

The value in this field should take one of the following forms:

• A domain name (translated into the actual IP address using a DNS query at the time the call is routed). This must be a fully qualified domain name, i.e., it should contain at least two names separated by a dot, for instance mytelecom.net. All other restrictions related to the domain name (e.g., permitted characters) apply as well. The resource record types used in DNS queries are: A, CNAME, SRV.
• Another custom name that helps to identify the connection, written in uppercase and without any dots.

Specify the maximum number of simultaneous sessions the connection can support.

If you have several connections with the same IP address (e.g., the same carrier offers you routes of different quality) and these can only be distinguished using the tech-prefix in the destination number, enter that tech-prefix here. This also automatically modifies the translation rules for this connection, such that the tech-prefix is appended to the number when a call is routed there, and removed from it when CDRs are being processed.

To receive calls from the vendor via this connection, specify the access number a customer diales in order to reach your network. If this field is empty, calls to any number dialed number will match. Leave this field empty if you have multiple toll-free numbers for calls to your network.

Info Digits is ISDN Originating Line Information (OLI) sent by the gateway. If call cost depends on OLI, select the corresponding Info Digits value from the list. Please note that the gateway should be configured to support OLI. For more information please refer to the OLI-Based Billing section of the PortaBilling Administrator Guide.

This option appears if you choose PSTN in Type of connections drop-down list. Node name connection that transport traffic.

The access code parameter allows you to use different rate plans for the Voice calls service, which are based on where the call originates from. Type the access code here.
