IP Public Address

IP Public Address(I2PA)

To manage enterprise organizations, you need devices to have efficient control on each part. IP-based devices are a perfect solution to manage sound issues; such as paging, playing special tracks, etc.

Your administrators can easily control the nodes, customize powering on and off, controlling volume, calling to a specific node or the whole as a pager.Easy to install and control.


Why IP?

Nowadays, almost all the buildings are equipped with a network infrastructure. The audio over IP technology has the huge advantaged to be able to use this existing network and to cross easily routers and even use the internet.

Where to use it?

You would be surprised if you knew where we have already installed Audio over IP solutions. From the standard applications like shopping malls, hotels, museums, theme parks, hospitals, schools to more tricky and original applications… IP networks are everywhere.


With I2PA, you will have a price competitive solution to answers to a lot of applications. By using the standard network and the POE technology you will simplify the installation and the network topology. Because it is IP based, the monitoring and the maintenance are simplified.

Powerful platform 

These small I2PA devices have a powerful processor, linux based. You will find a remarkable list of features like priority management, backup management, event management, scheduler, local channel and volume control, paging, echo cancellation, noise reduction.

Audio streaming 

I2PA offers the possibility to stream using the standard RTP protocol in unicast, multicast or broadcast. For some applications, like the Instore, the I2PA can stream using shoutcast/ icecast protocols.

SIP benefits 

All I2PA devices are using the SIP technology. It brings you the benefit to have a standard session protocol with its inherent simplicity, to be compatible with IP PBX & soft phone, to forget the complex management of IP address world.

PoE benefits 

All I2PA devices support the POE, Power Over Ethernet. With POE, the constraint of having AC power outlets is eliminated. This provides flexibility in placing I2PA devices in the most optimal locations instead of choosing locations where power is available. Optimal placement leads to more efficient network designs and better application performance. And if one day you want to change the location of your I2PA , it would be easier. The network installation can be accomplished easier, faster and for less cost. It is also safer because you can centralize the power management and protect it with an uninterruptible power supply (UPS). And finally with a manageable PoE LAN switch via a web browser or by SNMP, remote networking devices can be easily reset or shut down saving the time and expense of dispatching a technician.


we embed a web server that enables you to configure the I2PA through LAN/wifi. you can use the SNMP protocol for finding and monitoring all devices. the PASERVER will be your supervisor and the management solution of your installation.

During a city maneuver in Tehran, 50 IP-speaker system were tested in schools in order to teach students how to be control themselves and be aware during a disaster. After the project completely tested successfully, the whole 50 speaker were implemented in municipality’s subsidiary offices.

20 IP-Speakers were installed 10 floors of FAD building. IP-Speakers are being used not only for paging in different zones of this building, but they also play audio files like Adhan and Music.


Urban Observatory

    • Tehran Urban Observatory is an exhibit for highest rank city managers and decision makers, including members of City Council of Tehran, gives them information from Tehran Municipality Spatial Data Infrastructure (SDI), the three-dimensional map of Tehran, Tehran Real Time Kinematic (RTK), the Tehran map system and street view, the Information Technology Infrastructure Library (ITIL) and the network for social media of Tehran.
    • When we arrived at the site, there we a lot of interacting systems without an exact general plan or construction map.
    • We, as the observer of the project, documented all the project including all the hardware and software.


Telecom Hot Billing

Telecom Billing is a process of collecting usage, aggregating it, applying required charges and finally generating invoices for the customers. Telecom Billing process also includes receiving and recording payments from the customers.

Sending voice, data, picture, fax, etc., from one point to another using electronic media is termed as telecommunication and in short ‘telecom‘. Examples include Phone, Radio, Television and Internet. The medium of transmission includes Wire (Copper), Fiber Optics, Ether (wireless), Radio towers, Microwave, Satellite, etc.

Let us also list down a few basic telecom services being provided by various well known telecom operators −

  • Voice Call
  • Fax Service
  • SMS & MMS
  • Internet Connection
  • Data Download and Upload
  • Video Conferencing
  • IP based services, i.e., voice over IP or VPN

Billing systems are often viewed as accounts receivable, as the billing system assists in the collection (receipt) of money from customers. Billing systems are also part of accounts payable (for inter-carrier settlements), as customers often use services from other companies such as wireless roaming, long distance, and call completion through other networks.

After a call is made or you can say a usage is generated by the end customer, the mediation system gathers usage data from the network switch and builds a call-detail record (CDR). This CDR must contain ‘A’ party number and ‘B’ party number, the start and the end date & times.

The CDR is then stored until it can be rated. To rate the call, the CDR is examined to see if the call is, for example, an 800 number, a local call that is covered by a local-area calling plan, international call or a toll call. Information such as the time of the call was placed and city code or country codes are used to calculate the rate for the call.

Once each call is rated, this information is stored until the invoice is run, usually once a month. When the invoice is run, other nonusage charges, such as discounts or monthly fees, can be applied to the bill or sometime called invoice.

There could be a rating time discount or billing time discount, different payments done by the customers, different adjustments given, all these information contribute in the final invoice generation.

This information is then converted in a format, which can be printed in a readable form. Finally, the envelope is printed, stuffed with enclosures, and mailed to the end customer.

An event along with all its attributes is called Call Detail Record (CDR). A data collector in the network switch captures the usage in the form of Call Detail Record (CDR)/Usage Detail Record (UDR). These raw CDRs/UDRs are in turn converted by the mediation system into a format understandable by the Billing System.

There could be different network elements controlling the services and producing different types of CDRs; for example, for GSM telephony −

  • Voice calls are captured by the MSC (Mobile Switching Centre).
  • SMS traffic is captured by the SMSC.
  • Data traffic is captured by the GGSN.
  • MMS traffic is captured by the MMSC.
  • Roaming CDRs are captured by roaming partner’s switching element.

The following diagram shows the Network elements capturing Usage data and sending Raw UDRs to the Mediation System and finally to the Billing System for rating and billing.

As mentioned above, a CDR keeps usage details along with various other useful information. Below are the most important attributes of a CDR −

  • Calling Party (A number).
  • Called Party (B number).
  • Call Start (date and time).
  • How long the call was (duration).
  • Call Type (Voice, SMS, Data etc).
  • A unique sequence number identifying the record.

Additionally, a CDR may also record other information such as −

  • The identifier of the telephone exchange.
  • The result of the call (whether it was answered, busy, etc.).
  • Trunk or route used to connect the call.
  • Any fault condition encountered.
  • Indicators that note the use of features such as call forwarding, three-way calling, etc.
  • Any facilities used during the call, such as call waiting or call diversion.
  • Various other attributes depending on requirement.

The accurate recording of all required information in a UDR depends on the logic of the switch vendor plus the switch specific table entries. If either of these cannot record the data accurately, the mediation system will not be able to recognize the completed calls and pass them to the billing system.
