I am a totally New to Astrisk, and our company now needs a solution to set up a Astrisk system with the below features.
PABX system will reside in our data center with all users need to connect to the PABX over the internet using inbuild VPN’s in the phones. There will be few phones within the datacentre but majority of the users will be remote users who will connect the phones over their home ADSL/internet. The solution has to be secure and we can buy private IP if needed.
Since i am very new to this , any help in getting in getting the relevant design/deployment documentation and relevant hardware/Phones etc to support this type of scenario will be greatly appreciated.
Thanks in advance.
