Open Standards VoIP/UC Solutions

Voice over IP and Unified Communications are our fields of expertise. VoIP systems utilize the IP network to provide telephony services. This underlying technology makes many new features possible, like presence information with BLFs, integration of additional services like calendars and email, easier management of users and devices, and much more! These new features can be used to increase your productivity and availability, so you can be there for your partners and customers.

Individual Results with 3CX or SipXecs!

We don’t work with proprietary software, but with Open Standards. This means no vendor lock-in is a standard feature of our systems. Our customers are not tied to expensive hardware from one manufacturer. The PBX systems that we deploy are based on Open Standards software and encompass the following solutions: The open source version SipXcom, and the commercial version Uniteme from the software provider eZuce. The particular strengths of these solutions are both High Availability as well as the scalability. The solution from 3CX offers high-performance clients for mobile devices and PCs, as well as high resolution web conferences for all users!

Common deployment possibilities are listed below. Whether you want to integrate the new system with the existing PBX, or if a managed service is desired, with our offer, you remain flexible!

SIP Trunk Connections

When it comes to configuring SIP trunk connections, we are your specialists! We connect PBX Systems to SIP Trunks on a daily basis. Should interoperability issues arise, we can usually resolve them with a quick protocol analysis. We have connected PBX systems via SIP trunks from many providers in many countries, such as:

Colt, Deutsches Forschungsnetz (DFN), Easybell, Ecotel, Equada, Globalways, Intelepeer, QSC, Sipgate, Spark, T-Systems, TDC Trunk, Telekom, Vodafone, etc.

Integration of UCC Systems

With Open Standards, other UCC systems such as Microsoft Teams or Zoom Phone can be integrated into the telecommunications system. This way, your telecommunications solution stays flexible!

Smooth Migration


Smooth Migration

Smooth migration allows for the existing telecommunications system to be gradually replaced with the new system. This spreads the deployment costs over a defined time period, and allows existing contracts to still be used.

Cloud


Managed Services

Our telecommunications systems are also available as a managed service – either on-site or in the cloud! Find out more from our flyer.

VoIP Gateway Solutions

Gateways are very powerful network elements that generally act either as a translator between protocols, or to achieve enhanced security. For a VoIP system, they are used to allow for telephone calls across networks, for instance with participants in ISDN networks, or with analog devices. We at IANT have gained a lot of experience over the years with gateway configuration. We regularly configure and deploy them both in combination with our PBX systems, or as a standalone element as according to the customer’s specific requirements. Below you’ll find an overview of the gateways we regularly deploy.

IANT Point

ISDN Gateways
BRI/PRI

Common gateways used to facilitate a connection between VoIP networks and ISDN networks are BRI (Basic Rate Interface) and PRI (Primary Rate Interface) gateways, and differ by the amount of concurrent calls that can be handled.

IANT Point

Analog Gateways
FXS/FXO

Analog gateways establish a connection to analog devices, such as redundant emergency telephones for high security areas or elevators and fax machines.

SBC

IANT Point

Session Border Controller
FXS/FXO

Because VoIP systems use the internet for communication, security is a large concern for a company's network and telephony. Session Border Controllers (SBCs) offer considerable security through topology hiding. This means that sensitive coporate network data such as specific port information, IP addresses, etc. remain hidden outside of the coporate network.

We additionally offer customer specific development for GSM and LTE gateways. Click here for more information.

Critical Communications

In the field of Critical Communications we have a wide range of projects in our portfolio. Projects normally involve designing and implementing emergency telephony and alarm solutions for the public transport sector, as well as for high security areas in companies and research facilities. In the following list you’ll find a short overview of selected functions that we have implemented.

  • PA Systems
  • Redundant, Highly Available (HA) VoIP communications systems
  • Integration of highly secure, analog communications systems
  • Alarm Chains
  • Integration of special hardware like ATEX certified telephones and DECT handsets
  • DECT handsets with man-down alarms for lone workers
  • Positioning systems for personal tracking

Other projects include HA telecommunication solutions for railway infrastructure. The focus of such projects can include paging and announcement systems as well as telephone systems for trains, configuration and integration of emergency telephones or SOS call boxes, etc.

Remote Monitoring and SLAs

Once the VoIP solution has successfully been deployed, remote monitoring and Service Level Agreements (SLA) help keep your system operational. Many problems that occur with IP telephony can be recognized before they become critical. Our monitoring tools inform us quickly about problems regarding critical telephony elements such as telephony servers, gateways or the VoIP network; and with guaranteed reaction times and defined process standards, you can rest assured that you’re in good hands.

VoIP Readiness Analysis

What is the VoIP Readiness Analysis and why do we recommend it? This analysis is designed to help those looking to switch from a traditional PBX to a VoIP telephony system. Voice over IP transmits speech and signaling data over the IP network – in addition to the normal traffic. Real-time capability, crucial to telecommunications, imposes higher requirements on the network. Because VoIP technology relies so heavily on the IP network, it is important to test for vulnerabilities prior to migration to ensure a smooth operation.

To analyze your network, a test system is designed according to the size and complexity of the network to reflect the expected call volume. The measuring nodes and controller are installed on-site. These will simulate VoIP network traffic and measure data relevant to telecommunications. QoS parameters critical for VoIP, such as packet loss, latency, and jitter are measured over an agreed period (typically two weeks). After the analysis, you receive detailed indications of concrete vulnerabilities as well as recommendations for measures necessary to ensure reliable telephony. The VoIP Readiness Analysis is the first step towards migration, and can be performed independent of the decision for a specific telecommunications solution. For more information, see our flyer with the link below.
