Unified Communications With Elastix. Vol. 1 Pdf

for Smart Devices. Vol.2, No.2 (), pp Abstract. Unified Communication (UC) is the integration of two or more real time .. FreePBX is a full-featured. Unified Communications with Elastix is a work intended for users and enthusiasts of this distribution. It serves also as reference material for those who want to. an Elastix administrator or integrator to be able to design IP telephony and training material is the textbook: Unified Communications with Elastix Vol

The output of the project should be a modular architecture with additional functionality such as speech quality monitoring and security of IP telephony. Our intent was to develop a modular architecture for a SIP communication server with additional functionalities such as speech quality monitoring and protection against certain security threats. The entire system is distributed as an image is suitable for embedding hardware with low computational complexity. Alternatively, individual packages can be installed from SVN. Every software solution includes its own configuration and management. Accordingly, BESIP aims to be a scalable solution with an emphasis on security and a unified configuration [ 1 ]. The main advantage of our solution is the ability to easily and quickly set up a full featured PBX on almost any hardware.

We sought to unify the configuration of individual hardware with low computational complexity. In order to be individual packages can be installed from SVN.

Every soft- able to implement the idea into OpenWrt, we had to integrate ware solution includes its own configuration and manage- a complex support for the NETCONF configuration proto- ment.

The paper explains and describes the whole concept of the BESIP project and its 2 State of the art individual modules. The main advantage of our solution is the ability to easily and quickly set up a full featured PBX on almost any hardware. Our intent was At present, there are several projects that offer multipur- pose IP telephony solutions for embedded devices and for M.

The mon- of embedded devices, such as Raspberry Pi, is the reason itoring module exploits a tshark package and our developed why the Micro Elastix [4] distribution was born. However, tool which provides information about the quality of a par- all of those projects are either prepared for x86 machines ticular speech [10,11].

The Zabbix agent is used to report only or for specific hardware. Micro Elastix only supports basic states of the entire system. Also there is no module that Several open-source applications were adopted and imple- would monitor the quality of voice calls transmitted through mented into the developed modules.

Thanks to the portability of the OpenWrt dis- OpenWrt core module. This is due to a complicated porting of tribution we can prepare a BESIP bootable image for almost applications into OpenWrt buildroot.

Our patches were tested any device. Having observed and discussed various open-source solutions, OpenWrt was selected as the primary platform. There are many packages 3 Design of architecture included; packages not included can be added into the appli- cation tree.

There are four procedure, especially for packages without configure script, basic modules: OpenWrt is well-known for excel- First, we discussed the existing projects which we could lent support, solid ticket system, relatively good documenta- adopt and modify for our purposes.

We considered the fol- tion and cooperation with the community of developers.

Each of them configuration backend; offers its own semantics and configuration file. In addi- tion, configuration independent syntax will be available on all modules. During the first stage of the project, applica- tions and libraries were ported. The RPC request is initiated by a client that requests the configuration data or a command to be performed on the server.

The responses consist of a Fig. The libnetconf [17] library, which has been developed fully performed on the server. See Fig. The structure of of our implementation. The primary goal is to defines the semantics and syntax of a management feature provide a suitable environment for small routers with mini- [15]. Although CONF server and all requests and responses must comply the implementation is mostly problematic due to the cross with a firmly defined structure, specified by YANG modules.

Consequently, the stored these targets represents a set of variables defining parameters configuration data is accessible through simple queries. It for the generation of an image of particular hardware [12]. However, almost every application or management. OpenWrt deals away fully. Unified configuration interface UCI is netconf-subsystem which allows us to communicate with the the configuration interface in OpenWrt.

It is a group of configuration uration data format and create their configuration files from files which can be read or modified by common UCI API. UCI provides an interlayer between ration. The advantage of this approach lies in particular in the user and the application, simplifying configuration for the exact definition of the data model; possibility to call any users and unifying API for applications.

UCI only defines a format data model for interface configuration was applied to verify of configuration directives and access to them but not their proposed functionalities [16]. We combined several applica- exact content or relation to each other. First issue is into it [18,19]. The sec- how the system will work. Today, only one of these engines the formation of configurations from universal UCI files. The can be configured but in the future, both engines will work YANG model defines the exact configuration structure which together and will be configured by the common NETCONF enables to detach a substantial part of the code from current server.

Kamailio will be able to route requests even if Aster- applications. If users change the UCI file, the content is auto- isk is out of order. Billing is an important feature of every SIP server. In many systems, billing is divided into two separate steps.

These CDRs are stored in a text file or a repository. Generally, the module also data stored, i. Asterisk is used to distribute calls and requested criteria. This is a conventional scenario, classical performs the PBX functions.

Kamailio is used to proxy SIP approach of many billing applications and highly reliable requests, to normalize the traffic and to ensure security [5,6]. Even if When developing VoIP solution, there are always two fac- there is an issue with the billing software, PBX still operates tors involved. The first one is high availability and reliabil- properly. There is, however, one big disadvantage: Consequently, the stored configuration data is accessible through simple queries.

It makes the device quickly configurable, therefore a backup or a configuration restore can be performed easily and quickly. YUMA is a package which provides tools for the network management.

OpenWrt uses UCI as a configuration backend. The advantage of this approach lies in particular in the exact definition of the data model; possibility to call any function through a remote procedure call; data model editing in YANG and independence on client. The libnetconf [ 17 ] library, which has been developed by CESNET as an open-source project since , is a part of our implementation. The primary goal is to provide a suitable environment for small routers with minimum requirements on processor, flash and RAM.

Although the implementation is mostly problematic due to the cross compilation; the image generation for embedded equipment is very well parameterized. Each of these targets represents a set of variables defining parameters for the generation of an image of particular hardware [ 12 ].

However, almost every application or tool is configured in a different way. OpenWrt deals away with the issue how to configure more applications in one configuration tool.

All packages supporting this way of configuration can read the UCI configuration data format and create their configuration files from this data. The advantage lies in the independence of individual implementation.

UCI provides an interlayer between the user and the application, simplifying configuration for users and unifying API for applications. UCI only defines a format of configuration directives and access to them but not their exact content or relation to each other. That depends on the user. Typically if the user modifies the name of a network interface, the subsequent libraries will fail unless the modification is performed in all locations where it is necessary.

Our approach addresses two significant issues. Important: If you perform the procedure to change the port, you must check the Azure Network Security Group associated with the interface on the BIG-IP that was deployed and adjust the ports accordingly.

I checked for module updates I had the latest but still had this issue. But Google Voice would only work for 5 minutes at best using the degraded security state setting over at Google. OpenWrt is a Linux based distribution for embedded systems, with a strong integration of network components. I have no idea if this is at all possible, but it seems to me that if someone knows it's gotta be you. This guide is based on version UDPPorts: Lists of ports used by asterisk.
