We have supported many others in the past, but these have not been commercialized on our GTIGLOBAL network yet.  This includes platforms such as Cisco CUCM, Avaya Aura and IP Office, Mitel, and others.  These are all traditionally premised-based PBXs.  We have made a strategic decision to focus on cloud-based platforms initially since most companies are looking to transition to some form of cloud UCaaS.
We have plans to add to our cloud platform supported list with the likes of Microsoft Teams and other major platforms.  We are by no means done in that regard.
