Nartel Inc, VOIP integrator company, can provide a H323 and SIP softswitch with the following capabilities.
H323 switch
H323 gatekeeper
SIP Proxy
SIP registrar
Each of the described elements can operate simultaneously with the others. Moreover, the clients, regardless of the protocol, or the way they transfer connections, can connect between one another. This option allows connecting the networks, which because of the differences in implemented protocols or dialects inside the particular protocol, cannot directly transfer connection between one another.
The main characteristics of the softswitch include:
· Simultaneous and transparent support of SIP and H323 protocols (sip→h323 and h323→sip translator
· Possibility of implementing various types of proxy (e.g. RTP-proxy or signaling proxy), possibility of choosing proxy for each prefix defined in dialing plan.
· Advanced routing and rating system
· Full internetworking with most commercially available switches, softswitches, session border controllers and VOIP gateways.
· VOIP equipment support
· NAT support both for SIP and h323 equipment
· Calling to sip devices behind NAT (without the necessity of configuring NAT)
· Calling among users registered to VoipSwitch, support for dynamic IP addresses
· Authentication of VOIP equipment
o Through IP address
o Through ANI
o Through h323id
o Through the pair of login/password (according to the SIP standard)
· Flexible routing
· Individual, integrated billing system
· Managing pre-paid and post-paid accounts
· Setting up users in the configuration interface
· Managing users, blocking, setting limits
· Generating the groups of users and managing lots
· Creating and managing tariffs, the possibility of attributing a tariff to an individual user
· Data stored in the MSSQL or MySQL database
· Graphic management interface (presentation of the statistical data, billing information, managing clients’ accounts, generating PIN, managing the tariffs, dialing plan and others)
· Graphic interface presenting the current traffic in the real time, number of the logged in clients, with the division into different types of services, presentation of logs and others
· Web interface for clients – presentation of the connections history, possibility of exporting to the file, presentation of the current account status, possibility of making payments online and others
· Easy to set up architecture
· Automatic software re-start facilities in case of system failure
· Scalability for new telecommunication services by enabling additional modules
· Utilize possibility of implementing value-added services such as: calling card system, IPPBX, callback system using additional software packages
* Security and load planning of VoIP-traffic by using optional RTP-proxying
* Access to the statistical data (ASR, PDD and others)
* Transparent interface of the billing system
Available modules:
* IVR for calling cards
* Web/SMS/ANI callback (with IVR)
* Reseller’s module

Intelligent routing
1. based on prefixes (the possibility of defining prefixes differentiating individual users)
2. based on accessibility of the VOIP gateway
3. based on priorities when choosing a gateway
4. depending on available voice codecs
5. depending on prefixes specified in the tariff of an individual client
Phone Numbers Translation
1. Deletion of the set number of digits from the called party number
2. Addition of the set number of digits to the called party number
3. Deletion of the set number of digits from the caller number
4. Addition of the set number of digits to the caller number
5. Virtual prefixes (for differentiation of the dialing plans)
Information for the Billing System
1. Real-time, built in billing system
2. Storage in SQL database (MSSQL or MYSQL). Databases can be located on different servers.
3. pre-paid and post-paid accounts

System Management and Control Features
1. Graphic User Interface for managing the overall functionality of the system
2. Visual presentation of current connections along with the information on their status
3. The number of statistical data presenting the information on the traffic intensity with its various parameters e.g. ASR, PDD. Possibility of limiting the number of data presented by using available filters e.g. only incoming traffic from the particular client, traffic directed to the particular gateway, or prefix etc.
4. Visual presentation of logged in clients and their current status, with the division into types of services e.g. gatekeeper users, SIP users, pc2phone, callback.
