Mitel Networks is a high-tech company providing unified communications solutions for business. The company previously produced TDM PBX systems and applications but after a change in ownership in 2001 now focuses almost entirely on Voice-over-IP (VoIP) products.
Products from Mitel acquisition Aastra Technologies have been tested by Dialexia to operate with its VoIP IP PBX and softswitch platforms and applications. Tests made include inbound and outbound calls, call transfers, IVR interaction, and CODEC negotiation. In order to ensure interoperability, Dialexia certifies and supports only specific combinations of third party hardware and firmware.
