PBX stands for Private Branch Exchange, which is a private telephone network used within a company or organization. The users of the PBX phone system can communicate internally (within their company) and externally (with the outside world), using different communication channels like Voice over IP, ISDN or analog. A PBX also allows you to have more phones than physical phone lines (PTSN) and allows free calls between users. Additionally, it provides features like transfer calls, voicemail, call recording, interactive voice menus (IVRs) and call queues.

Traditional PBXs would have their own proprietary phones, such that there would be a way to re-use these phones with a different system. This means that we either have system-lock-in (we are bound to the same system because changing system means also changing phones, which makes it prohibitively expensive to break away) or vendor-lock-in (we are bound to the same vendor because the phones are only usable with systems from the same vendor, sometimes only within a particular range of systems).

Time and technology, however, have changed the consumer telephony landscape, with the flag-bearer being the Open-Standards-based IP PBX. The point of the “IP” in this new era is that the phone calls are delivered using the Internet Protocol as the underlying transport technology.

One of the major benefits using UCM6XXX VoIP IPPBX systems is “Clients’ Mobility” allowing users to be connected from remote locations such as home office, remote office to the VoIP system and use it as if they are locally connected, enjoying all VoIP features (making/receiving calls between extensions, voicemail, call transfer, video calls, conference, using UCM6XXX resources such as SIP and analog trunksremotely…).

Customers using UCM6XXX are no more restricted to be physically connected to the same network as UCM6XXX, opening borders for them to be connected from anywhere in the world across Internet network.

GSM GATEWAY INTEGRATION

IP-PABX with GSM/UMTS Connectivity With GSM/UMTS technology becoming one of the major wireless communication technologies, GSM communication occupies 70% of the wireless communication market and takes on an added importance in business communication. As the most economic wireless communication solution nowadays, it even costs less than wired system.

IP PABX is a GSM IP-PBX that integrates GSM with enterprise telephone network. It not only reduces telephone expenses but also provides crucial communication link for remote offices lacking fixed lines.

Yeastar GSM Gateway models TG100,TG200,TG400,TG800,TG1600 supports 1,2,4,8,16 simcards respectively.
