Pure IP-PBX

Introduction

Business today has extended beyond the geographic boundaries. The requirement of modern age businesses and professionals have changed and grown. The way-of-work is no longer limited to voice based communication. The requirement today is of a communication technology that is cost-effective, boundless, decentralized, flexible and efficient.

That’s the reason the world is advancing towards IP telephony. IP telephony is highly cost-effective. The IP network is wide-existent, making communication boundless. An IP user is free to carry his extension anywhere on the global IP network. This facilitates a decentralized communication setup. IP telephony offers wider flexibility in choosing the mode (call, IM) and the terminal (IP phone, a soft phone, mobile with SIP client, PDA) for communication. Presence and IM functionalities have completely changed the way organizations work and account for improved productivity.

Centralized IP Server for Dispersed Users

The All-in-One IP-PBX embeds the otherwise distributed SIP Registrar, Proxy, Presence and Voice Mail Servers to a single element. The comprehensive, full-featured and compact IP-PBX is capable of handling up to 500 users. There are two models – SAPEX SDM with 200 users and SAPEX DDM with 500 user support.

Dispersed branches or IP users can be tied together over the IP network, with SAPEX IPXP located at the main office unit. Devices such as IP phones, ATAs and Gateways, with support for SIP, can be easily registered as clients to the IP server. Such multi-site connectivity over IP facilitates usage of common dial plans and numbering across the geographically dispersed branches. Low-Tariff internet telephony between geographically spread locations helps to reduce the communication cost to a great extent. Multiple Extensions can be grouped under a single user group. This facilitates call distribution between pre-defined users, as per the assigned priorities. These Users can be virtually located at different locations on the IP network. The seamlessly connected users can share a common Auto Attendant and Voice Mail system also. A built-in RADIUS client facilitates efficient call logging to a remote server. The SMTP client paves the way for the voicemails to be picked-up from a user’s voice mail box and efficiently delivered to a user’s Email-ID as attachments. A user has the flexibility to receive a scheduled delivery of such voice mails. Centralized Management, Reduced Administrative and Communication cost, Extended Mobility and Enhanced Productivity are some of the apparent benefits.

Simplified Configuration and Management
SAPEX IP-PBX accounts for simplified communication architecture, as it is now possible to route calls also over the IP network, besides data. With the embedded web server, an administrator can remotely program and configure the system using the Multi-Lingual Web based Programming GUI. An administrator can monitor and manage user registration and feature access in real-time. An SAPEX extension can be located anywhere on the global IP network. A new user can be added, granted calling rights, defined under a user group, granted voice mail access with a few clicks from the intuitive GUI itself.

Remote User Connectivity
A SIP user located over a Public/Private network can be registered easily with SAPEX IP-PBX without the need to use VPN or other tunneling technologies. The embedded Dynamic DNS client ensures a remote user can register to the IP server configured for a dynamic IP without much trouble. In the world of IP, an end user terminal can be an IP phone, a soft phone, mobile with SIP client, PDA, etc. A user can have multiple contact points mapped to a common user identity. A user can be reached on any of the active terminal at a given instant, with the flexibility to register from any geographic location on the IP network. Presence further determines the availability of a user (such as online, offline), his willingness to participate in a communication session (busy, available on phone, out of office and others) and his preferred mode of communication (Call or Instant Messaging) before an actual conversation begins.

World-Wide Extension Portability
SAPEX IP-PBX is a SIP server with capacity to register as many as 500 users. In IP telephony, a VoIP call is established over the IP network. Unlike, a traditional telephony system, SAPEX IP-PBX does not bind a user to a fixed location. Instead of a phone number, an IP user is identified by his SIP URI. An IP user is free to carry his extension anywhere in the world. Wherever a user is, provided with an adequate Internet link, users can establish calls retaining the same contact credentials.

Open-Standard Architecture
SAPEX IP-PBX supports open-standard SIP protocol to establish calls over the IP network. Following the route of open-standard, SAPEX IP-PBX is ensured for full interoperability with an entity with SIP support. Thus, moving towards the next generation IP telephony with SAPEX IP-PBX, an organization can also integrate to existing telephony network through the gateway devices and thereby plan for a smooth migration to a full IP-based infrastructure.
