Hi guys ! I'd like to b build a call center having as system base the Elastix 1.6 and the call center module 1.5. My Elastix will be connected with PSTN through PRI line and I'm looking to buy the digital card (T1/E1) TE122B from Digium. Could you please tell me if that card will work well with Elastix 1.6 ? Is there needed any upgrade of dahdi or libpri modules ? Apart that card I'm looking for, could you please what hardware do you recommend for a PRI (E1) connection ? Thanks in advance for your answer and help ! Cheers!
