We are facing the following problem . We have an Panasonic Kx-TDA 600 which is connected to several Voice providers. I want to add an Asterisk server and make the following connection:
Voice Provider -----KX-TDA 600----Asterisk–200 users.
Asterisk will serve about 200 users , which must have a internal extension but also an unique public phone number routed to KX-TDA.
So for eg: user 1 on asterisk will have extension 123 and extension +001 254314etc . When a call is made from user 1 to the world it should go from asterisk to KX-TDA and forwarded to one of the Panasonic Voice Provider. When a call is made from outside to user on the KX-TDA 600 will fw the call to asterisk and finally asterisk to final user.
Is it possible to have this type of configuration , if yes , what cards i will need on asterisk ?
Many thanks in advance.
