I wish to install a 8+ modem card in my elastix server. what brand/mnodels are certified with Elastix that are not outrageously priced? I would like to connect 8 POTS lines to the modem. Also, I was thinking of a fractional PRI connected to a T1 Card. Will Elastix/Hylafax work better with a PRI for fax purposes. Also, the T1 card will allow me to use the PRI as a fail-over trunk in the event my Sip trunk and internet go offline. thoughts? suggestions? Currently, a small but important percentage of customers are complaining about not being able to send faxes over our sip trunk. I would like to make the fax solution bulletproof and less costly than migrating to a service like efax or GFI Faxmaker.
