Settings description of PBX and IP PBX

It is increasingly more common for organizations to acquire, install and maintain hardware components, such as the central switch (PBX) or IP PBX, which are required to admit their own telephone systems. Many organizations purchase their own telephone equipment and train its staff to reduce costs associated with maintenance of its telephone systems and because they want greater control of telephony features offered.

For an organization to possess and maintain a telephone network, you must purchase the hardware needed. It should also take into account the daily maintenance of telephone equipment and training necessary for your staff to manage the telephony system. This topic discusses the different types of telephone systems and business or organizational components of telephony hardware required. It also provides examples of different types of telephony configurations.

A PBX is a legacy PBX telephony device that switches calls in a telephone network or circuit switched. A legacy PBX is a PBX that does not have a network adapter and can not transmit packets. Not being able to transmit IP packets, some companies and organizations have replaced legacy PBX to IP PBX. For a list of supported PBX for Exchange 2007 Unified Messaging, see Telephony Advisor for Exchange Server 2007.

Most companies use medium and large PBX. PBX enables users or subscribers to share a number of external lines for making telephone calls are considered as external to the PBX. A PBX is a much less expensive to provide each user with a telephone company outsourcing. A PBX can be connected telephones, fax machines, modems and other communication devices.
Typically, the PBX equipment is installed in the organization itself and connects calls between phones in the organization and the telephone company. Normally, there are a limited number of external lines, called trunk lines, to make and receive calls outside the company from an external source such as the PSTN.

To enable a legacy PBX for use with Exchange 2007 Unified Messaging, you must implement a gateway IP compatible. For a list of IP gateways, see Telephony Advisor for Exchange Server 2007.

IP PBX An IP PBX is a PBX that has a network adapter compatible with the IP protocol. It is a piece of telephone switching equipment that normally resides in an organization or company rather than being located in the offices of a telephone company. There are two types of IP PBX: IP PBX and IP PBX traditional hybrid. Both traditional and IP PBX, IP PBX hybrid are consistent with the IP protocol for sending voice conversations in packets based VoIP phones. However, hybrid IP PBX also connects traditional analog and digital phones.

IP PBXs are frequently easier to manage than the legacy PBXs, because administrators can easily configure the IP PBX through an Internet browser or another IP-based tool. Furthermore, it is not necessary to install cables, wiring, patch panels or additional. With an IP PBX, to move an IP phone based simply unplug it and plug it back elsewhere. This avoids the costly services needed to move a phone from a legacy PBX provider. Likewise, organizations that own an IP PBX do not have to bear the additional costs of infrastructure needed to maintain and manage two separate networks for circuit switched and packet switched.

IP PBX Configurations

An IP PBX is a PBX that supports IP phones to connect through an Ethernet LAN or packet switching. Send IM conversations into data packets or IP. An IP PBX can have multiple interfaces. These include interfaces to a data network and other interfaces that allow connection to a telephone network or circuit switched.

The development of Internet protocols in real time has been correctly can send voice messages and faxes by a data network. Among these protocols of the Internet in real time including VoIP protocols that are used with Exchange 2007 Unified Messaging: Session Initiation Protocol (SIP) over Transmission Control Protocol (TCP) for voice and T.38 messages to faxes. These protocols have been successfully able to send voice messages and faxes by a data network. VoIP protocols in real time are necessary to maintain order and control the delivery and synchronization of data packets to send voice messages through a data network or circuit switched. Failure to use these protocols to maintain and control the delivery order and synchronization of data packets, the voice of the people would decompose and the sound would be inconsistent or images could be confusing.

7 Keys to Investing in IP-PBX Telephony for the Economic Crisis

The natural reaction of all the constant news about the global economic crisis is to succumb to panic, while it should be focused on the challenges and pay attention to the revenue stream for our business remain in a reasonable manner. So it is good that a crisis is also opportunity, and this includes the possibility to get more of what you need while investing less in this case IP/PBX Telephony is the perfect partner to create opportunities.

Crisis Image:

An important point to remember is that technology vendors are also facing the same challenges that their company and the tendency may be to submit tenders in order to maintain cash flow, so that you can take the opportunity to do better business taking into account the following key:

1. Be sure to RFPs (Request for Proposal) and detailed request for purchase. In the current environment is a necessity in the battle to tackle the various vendors. Rather than simply choose the vendor who offers the best price or the proceeds from fashion, to select him for better services or value-added benefit to your business even in the medium or long term. Do not believe that RFPs are only for major purchases, if they are useful to buy a communications system for 500 users will also be for a 20.

Do not use any RFP. Using an RFP out for wrong or make a purchase may be worse than not using any. For example, the section of specifications must be clear and concise to avoid ambiguous phrases or signs that leave out one or more sellers then you can not negotiate the best terms.

Note that some sellers who fail to fulfill the offerings send confusing trying to confuse the purchasing staff, so the recommendation is simple: If you is not considered an expert in the field, try to hire a consultant to help you deal with suppliers who send their tenders. If your budget does not allow him to hire a consultant, consider laying at the same table on the same occasion to different proveedoresde way to openly explain their advantages, open competition between them will serve as counsel for purchases.

2. Get a contract of one year or more for the support and maintenance. If you expect your company to continue to grow after the crisis or recession, then think of buying long-term with the best prices today. It is always more effective to achieve volume discounts in the purchase of equipment, software or services if you will require for a year or more. The advantage of this strategy is that you pay less when the crisis ends and your company the momentum back before.

3. Try to get new features and / or additional services with your purchase. If you are buying an IP/PBX, there are things that your provider can offer and that the manufacturer will cost you as little or nothing, and if this is the difference in winning or losing a purchase insurance you will get. Try to negotiate services such as Unified Messaging, Reports, Call Center Management Conference, or that might be of interest for your company and does not come as part of the standard provider.

4. If you are upgrading or updating an existing system, consider a new fund. If you also considered a process or Rent Financial Leasing, could opt for a grace period without payment and also consider the tax benefits that this could lead to your company. This way you move the investment to a longer period during which the crisis could have ended while being smaller payments over time.

5. Ready to buy now. In times of recession, dealers need sales now, not six months or a year, so that sellers are ready to make concessions if you buy them now. Cisco System for example, gave greater discounts in 2008 than in 2007, reflecting that made many more concessions during the difficult days of the recession of 2008 than in 2007, good morning. The important point to remember here is that the offers and concessions are valid and will last until the seller decides, so buying time is an important factor.

6. Be ready to change their suppliers, especially in services. Many providers of communication services are more interested in getting new customers to maintain existing ones, if you are renewing a support contract hardly get additional concessions, but if you negotiate with a new provider of this insurance is willing to give advantages.

The problem here is that switching supplier can be more costly than the benefit you get with a new one, so you must choose correctly to your new provider or even sit down with your current provider and show an analysis of the possible decision to change the supplier of insurance that will attract your attention and you move to take more account of his company during the negotiation.

7. Become a showcase of technology purchases. Although this factor is not as easy as in the early days of VoIP, while sellers may be willing to include some names to its portfolio of clients associated with your brand or product. If your company is ready to open the doors and window displays of the technology you purchase is also possible that the seller is willing to provide additional services or even some discount.
