Gigaset pro devices are telephony devices, designed to be connected to SIP platforms. There are many Internet telephony service providers (ITSPs) or private branch exchange (PBX) systems that offer the (SIP) services for our Gigaset pro devices.  As every platform is different and offer different telephony features, every device needs to be tested against this platform to check the functionality.

On our wiki, we have a list with ITSPs and PBX systems where we have tested our Gigaset pro devices against. If your ITSP or PBX is not listed, we do not know if our Gigaset pro devices are working seamlessly together. If you encounter problems and we do not know this platform it is not possible for us to support you.
