Oracle is the 4th vendor to be certified for Microsoft Teams Direct routing (5th technically, but enterprises can’t buy Thinktel’s carrier SBC)
The Oracle AP 3900, AP 4600, aP 6300, AP 6350 and Virtual Machine Edition (VME) are all now certified. As with all SBC’s, they are pending for Media Bypass.
Note Acme Packet is the company Oracle acquired.
