Telecom and VoIP/UC monitoring works on the phone system you use, no matter the phone system and manufacturer of the equipment (e.g., Cisco, Avaya, Skype for Business, 8x8, Mitel, ShoreTel, RingCentral, Genesis, NEC, Aastra, Dell, and Asterisk).
We look at the network conditions that cause problems for VoIP/UC systems independently of the equipment's vendor.
