Connect a Konftel conference phone to IP PBX
A corporate PBX for IP telephony handles both analogue calls sent over the public switched telephone network (PSTN) and IP calls transmitted over data networks and the Internet. Konftel’s conference phones can be connected to this kind of PBX in any of the following ways.
1. Connection to an analogue port or phone adapter
A corporate PBX for IP telephony normally also handles analogue phone connections and all that is required is an analogue connection to the room where the conference phone is being used. It is also usually possible to plug an analogue telephone adapter (ATA) into the digital port and connect the phone to the adapter. The Konftel 250 and Konftel 300 have analogue connections.
2. Wireless solutions
If a DECT system for wireless telephony is connected to the company’s IP PBX, the Konftel 300Wx makes an ideal choice as it can be moved from room to room. If the PBX supports mobile connectivity (MEX), the same applies to the Konftel 300Mx or to a Konftel 55 or Konftel 55Wx on a mobile connection.
3. Desktop phone connection
The Konftel 55 and Konftel 55Wx conference units can be connected to an IP desktop phone. The unit converts the phone into a conference phone that delivers the same outstanding audio quality as Konftel’s stand-alone phones.
4. Connection to a PC
A PC with IP telephony (softphone) software can be used for calls to users of the same software or to communicate via the corporate IP PBX. The Konftel 55 and Konftel 55Wx are top choices for quality audio. Unlike the PC’s integrated speakers and microphone, a conference unit with Omnisound® delivers powerful audio with full duplex, echo cancellation and static reduction over the full audio bandwidth. The Konftel 300, Konftel 300Wx and Konftel 300Mx conference phones can also be connected to a PC via a USB cable.
5. Direct connection to IP PBX
The Konftel 300IP, Konftel 300IPx and Konftel 800 offers the perfect solution for companies with IP PBXs (SIP). It is directly connected to the PBX and uses all the advantages of IP telephony. It also provides advanced teleconferencing features with audio quality that is not limited by the normal bandwidth of the telephone network, a conference guide to simplify calls to conference groups, flexible management of multiple phone lines and integrated web server for ease of configuration and management of contacts.
Connecting the Konftel 300IP, Konftel 300IPx and Konftel 800
The Konftel 300IP, Konftel 300IPx and Konftel 800 are SIP based conference phones that are ideal for companies using, or planning to use, IP telephony. Here we explain the differences and advantages of the various IP telephony options.
Service provider
-
The Konftel 300IP/300IPx/800 connects to the corporate network/Internet and is registered in a SIP server with an operator or IP telephony service provider. The service provider is connected to the public telephone network and calls are normally routed via this network.
- If the service provider is represented in more than one country, it may be possible to make “local calls” to other countries. The cost of the calls will vary, depending on the service provider agreement. However, the calls are normally cheaper than regular phone calls and are often free within the operator’s own IP telephony network.
- This provides individuals and small companies with a simple solution and does not require them to do administration.
Softswitch
-
The Konftel 300IP/300IPx/800 connects to a softswitch, i.e. software in a PC that operates as a PBX and manages IP call connections or connects them via a gateway to the public switched telephone network.
-
Companies with offices in different cities or countries can be connected over the Internet to the same switch or each office can have its own softswitch. With either of these options, there are no call costs for internal calls and digital calls with other IP telephones.
-
This provides a flexible solution for any size company. The softswitch can usually be managed by the company’s IT staff or can be managed by an external provider through a service agreement.
Traditional PBX
-
The Konftel 300IP/300IPx/800 connects to a corporate IP PBX. All modern PBXs are directly compatible with IP telephony or via optional equipment.
- An IP PBX offers the same functionality as a software PBX for IP telephony. It can also manage other types of telecommunications and is usually more suitable for larger companies.
- This can be an efficient solution for smaller companies that already have a traditional PBX, and for larger companies that require the capacity and operational reliability that a traditional PBX provides. The PBX is normally managed through a service agreement with an external service provider.
SIP stands for Session Initiation Protocol and is a standardised protocol (communication regulations) for connecting phone calls via networks – in most cases via the Internet too.
