Yeastar SOHO MyPBX VoIP Phone and Device

Thank you for your question, you can run up to 10 lines with the unit. Four of the Yeastar Gateway TA410 or TA810 serial ports are already on this unit. The other two must come from the TA410 or You will have more lines on your system as a result. I hope this can be of help to ALAN / GLOB-

In the end, I did not buy the IPBX, but in response to your question , if your PBX supports SIP, you can configure SIP Trunks between those 2 PBX*br>it takes both times to configure it.

I am Dave Shaw, I am aware that the small cards comes with 2 FXS ports, but the small boards come with two FXO ports. Hence you can use either one of the two ports. From Yeastar, the units are named in order of the type, O2 or SO. In case of need, we have it in stock and ready to go. I hope you have a good time. I am Alan

The FXO or FXS does not come with this. As of now, SIP is only available out of the box. To add modules, you would need to do so. If you have any further questions, don't hesitate to contact us.
