I read that starting with Asterisk 1.6 libpri also includes BRI support, therefore providing an alternative to mISDN.
Is it true? How can I configure my Linux Box to work with this solution?
yes, it is true. there is one module called wcb4xxp for BRI cards in dahdi-linux-2.1.XXX. need more testing!
you have to install asterisk, dahdi-linux and libpri. get more details from here:
