Recently I have discovered more about irqs, timing delays, and the difficulties/impossiblities of switching hardware from vm instances than I ever wanted to know. Given that we have three dedicated fax lines and 6 voice is there any hardware that would you suggest for a 4 core x86_64 Intel based host system? We have looked at going completely to v/f-oip but I do not have the time to deal with those intricacies and get this move completed at the same time. So, for the nonce it appears that we would have to employ an FXO gateway to connect our existing POTS lines to the host. -- *** E-Mail is NOT a SECURE channel *** James B.
