Hi ,
I want to purchase Session Boarder Controller for my VOIP phones registration over the Internet (to act as proxy server) and not let any phone direct connected to my PBX , I have read about Cisco CUBE but I did not see any configuration guide for my case , cisco only talked about that CUBE has vpnless feature that allow cisco ip phone to register on CUCM over the internet , I also read about Nano-CUBE and I am not sure if it for third party PBX , anyone could clarify if Nano-CUBE can work as SBC for 3rd party PBX or I have to find another SBC from another vendor
Thank you for your support
Regards,
