** Here are the hosted platforms we support today:

    Asterisk (v16+)
    Broadsoft Broadworks
    PortaOne
    LG-Ericsson
    Netsapiens
    MOR Softswitch
    FreePBX
    GTI MAX (OV5x)
    Asterisk any type
    3CX Servers

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.
