The Hybrid IP PBX Yeastar MyPBX Standard :
test and overview of main functions
Yeastar MyPBX Standard is a hybrid IP PBX implemented in the form of a ready-to-use device.
This PBX has a wide range of possibilities for connecting to telephony operators, as well as to on-premises analog telephones through the use of interchangeable interface modules.
This model of the IP PBX Yeastar line can be characterized by performance (up to 25 simultaneous conversations), licensed capacity (up to 100 subscribers), and the number of interface modules that can be installed in it (up to 8 modules of different functionality). These modules allow servicing of E1 streams, they can be used as FXS/FXO , GSM interfaces etc. In addition, the possible number of extensions can be increased by purchasing additional licenses.
The opportunity to have a detailed look at this IP PBX model is a courtesy of IPMatika company.
Like all other models in the range of Yeastar IP PBX, MyPBX Standard was designed for medium-sized businesses (and is affordable). Just like other similar devices it is based on Asterisk open source software. Below you can see description of the most important features of this PBX.
1.The PBX is managed through Web interface, but it is also possible to connect to it via SSH and make adjustments with the use of Asterisk configuring files.
2. Connecting to the telephony providers. This PBX can be connected to telephony providers via SIP protocol or (provided you have installed relevant interface modules) via E1 (BRI) or GSM. It is also possible to use analogue lines if you install interface modules which have FXO ports. An example of a connection scheme can be seen in Picture 2. The window for SIP or IAX trunk tuning (for interaction with a telephony provider or another PBX) can be seen in Picture 3.
3. Connecting to extensions. IP telephones can be connected to the PBX through the local area network. In case you want to connect analogue telephones, interface modules with FXS ports should be used. Such modules are installed into the station case. Otherwise you could use external FXS gateways that are connected to the PBX via the local area network, and to the telephones through analogue lines. The overall number of extensions you can connect to PBX is limited by the license.
MyPBX interface for managing extensions is shown in Picture 4. There is an option to create groups of extension numbers, e.g. from 501 to 510, as well as set up parameters for such groups (passwords, IP-address restrictions, etc.), as shown in Picture 5.
4. Setting external routes is done through the interface shown in Picture 6.
5. When setting IVR (Interactive Voice Response), you have an option of selecting single level functions, which are performed when the caller presses certain buttons while the IVR is playing. For example, while the message of ‘Press 1 to connect to the sales department, press 2 for Technical support’ is playing, the user can press one of the proposed buttons and the PBX will perform the pre-programmed action. Managing the IVR is done through the window shown in Picture 7.
6. In the queue settings you can set the function of voice messaging at certain periods, to inform the caller about the expected waiting time and position in the queue. It is also possible to assign static agents (operators) to receive calls, and set some other parameters. The details of queue setting are shown in Picture 8.
7. The PBX can be used as a mini call center since there is a function of queue management and IVR options. It is also possible to connect MyPBX to external queue monitoring systems like Loway QueueMetrics. In addition, there is an option to access the PBX via SSH and AMI interface. You can see the window of AMI interface settings in Picture 9.
8. You can start recording the conversation during the call by dialing a faeture code (which is *1 by default). Other feature code settings are shown in Picture 10. Automated call recording option is available in Yeastar MyPBX UXXXseries.
9. Auto Provision feature automatically identifies Yealink and Aastra telephones connected to the local area network. Then telephones can be tuned through the same interface (see Picture 11).
10. Network settings. You can create 2 VLANs on the WAN port and 2 VLANs on the LAN port. This will allow direct connection to two separate telephony providers. There is also an option of setting a network firewall (see Pictures 12 and 13). The PBX has the Fail2Ban function, but it does not have an option to set any parameters. IP addresses are unblocked automatically by the timer.
11. Backup copying /restoring is done in the corresponding window (see Picture 14). In case of using automated backup it’s necessary to assign a File Share network directory.
12. Call transfers are set for each individual extension, either with the Follow Me function for the states of ‘busy’ and ‘no answer’ (see Picture 15, 16), or with the help of feature codes. In any case the settings are done through the Web interface. Call transfers are performed by using special adjustable feature codes (see Picture 10).
13. In case of analogue lines connection via the Yeastar SO module, Yeastar MyPBX will enable a certain degree of fail protection during power blackouts. It is accomplished by automated re-connection of analog telephones from FXS ports to incoming FXO ports, thus telephone connections are kept available.
14. Each extension user has access to a personal dashboard through the web interface. With the dashboard, the user can listen to voice mail and call recordings, set passwords for voicemail or set the redirect mode. See Picture 17.
