LANCOM 1823 VoIP is a highly integrated all-round solution offering a telephony gateway, VPN router, access router, professional firewall and WLAN access point.

As a business VoIP gateway, the LANCOM 1823 VoIP belongs to the LANCOM VoIP portfolio and offers interfaces for SIP and ISDN terminal equipment along with additional connectors for analog telephony.

Typical application scenarios include single sites or branch offices with up to 10 telephony subscribers using ISDN and/or analog terminal equipment - such as DECT telephones or fax machines - which is to be integrated into VoIP communications.

Particularly interesting for overseas subsidiaries without ISDN, the LANCOM 1823 VoIP allows existing analog telephone equipment to be used for VoIP, so providing investment protection and cost savings.

More Telephony.
Telephone calls can be automatically directed over existing VPN connections between company sites. Not only are these calls secured from interception; by using flatrate connections, there are no additional call costs, either.
Small and mid-sized companies can even save themselves complete PBXs by equipping new installations with a LANCOM VoIP gateway instead.
LANCOM opens up a cost-effective migration path between technologies of the “old and new world” because existing ISDN and analog telephones and PBXs can be integrated and operated side by side with SIP terminal equipment.
An internal ISDN and two analog connectors provide four simultaneous voice channels for optional combination with an analog or ISDN exchange line. For example, this allows an existing ISDN PBX to be equipped with SIP, enhanced with analog and SIP terminal equipment, and additionally to be connected to an upstream VoIP PBX over VPN. Subscribers can simultaneously make calls via ISDN telephones, analog phones, SIP equipment or softphones to other SIP or POTS subscribers, both internally and externally. The transition between analog, ISDN and SIP is automatic and invisible to the user.
With life-line support either between the internal and external ISDN ports or from analog to analog, telephony remains possible even when the router is switched off. SIP connections with redundancy and high reliability are ensured by backup over ISDN or analog exchange line, load balancing, and VRRP in combination with an Ethernet port as an additional WAN interface. This ensures that telephony is just as reliable as ever, even with Voice over IP.

More Security.
The integrated firewall with the latest security functions such as stateful inspection, intrusion detection and Denial-of-Service protection is supplemented by dynamic bandwidth management and comprehensive functions for backup, high-availability and redundancy. The integrated VPN gateway that fulfills the IPSec standard, and the optional hardware accelerator provide optimal security for connecting telecommuters and branch offices thanks to the high-security 3-DES or AES encryption and support of digital certificates.

More Freedom.
In particular for smaller sites like sales offices, the LANCOM 1823 VoIP is the universal solution for secure voice and data communications. Thanks to the integrated dualband access point compliant to IEEE 802.11a/h/b/g, this all-round gateway provides high data throughputs at up to 54/108 Mbps for mobile applications, and professional security with WPA2, LEPS and IEEE 802.11i - just as business users would expect.
In combination with suitable terminal equipment for Voice over WLAN, a whole new level of freedom is available for flexible working and organization. LANCOM 1823 VoIP supports wireless SIP telephony, specialized Quality of Service and fast roaming compliant with IEEE 802.11e.

More Benefits.
The versatile functions for address translation and routing allow the connection of completely different networks over common infrastructure. Existing networks at partner companies, home-office workstations or subsidiaries can be integrated into the VPN without problem. The management systems LANconfig and LANmonitor are included and offer not only cost-effective remote maintenance of entire installations along with highly convenient setup wizards, but also full real-time monitoring and logging. What’s more, service providers benefit from the broad range of scripting methods and professional access with individual access rights for administrators via SSH, HTTPS, TFTP and ISDN dial-in.

More Certainty for the Future.
From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back to older product generations, updates to the LANCOM Operating System—LCOS—are available several times a year, free of charge and offering major features.
