i want to use channel bank so i can have 24 analog phones or more
my question is i dont have and i dont want to connect to T1 service provider
just from Central Office (CO) or PSTN or analog phone provider
do i still need to have T1 card in my Asterisk Box and connect to Channel Bank?
is this will work having T1 Card without T1 service provider in Asterisk PBX with 24 port RHINO Channel Bank?
