Landstar Telecom Components
The Landstar Telecom network consists of multiple redundant server clusters hosted in Atlanta, Dallas, Las Vegas, and New Jersey. All of our servers operate in an Active-Active configuration, which means that the service is available from the primary or backup cluster at any time. A further level of redundancy is achieved by using High-Availability (HA) Pairs. In the event of a hardware or software error, the HA spare server will assume the IP address of the server with a problem and assume its operations transparently.

Provisioning Servers

The Landstar Telecom device provisioning servers allow you to Provision any number of SIP devices remotely, without having to manually configure handsets. The device provisioning servers are available at http://sipcfg.io/cfg.

All customers are assigned a primary and secondary PBX node. Supported SIP devices utilize DNS SRV records in one way or another and have awareness of the primary and secondary server through this record.

Web UIs

The primary Web User Interface for Landstar Telecom is called the PBX Portal.

To see an example, you can view https://portal.landstartel.co. We have Portal servers located at each of our Points of Presence (POPs). Your PBX Portal will be located at the same Geographic location as your primary PBX node.

SIP Servers and failover

Your phones and/or SIP Trunks REGISTER to their Primary server (as defined by the SRV records mentioned above). Other PBX servers keep track of the active registration, if they receive a call for a device registered at a different Geo Location, they will always direct the call to the node where the phone is registered. In the case of a failover event, the phone registers to the backup server until the primary server is once again reachable.

Behind the scenes, there are many other SIP Servers at work, such as ENUM Gateways and Ingress/Egress Proxies. These are largely hidden from your view, and we do not expose the inner working of our Network. The diagrams below show the typical call paths taken for Inbound and Outbound calls from a registered SIP device.
