We are investigating the possibility of using Asterisk in a KVM based virtual machine to handle connections to and from our HylaFax service. Our current set up uses a dedicated host with external fax modems. What I wish to know is what interface card would the list members recommend for a proof of concept trial?
We currently have two incoming fax lines and five vox lines all POTS. Our physical internet connection is fiber but I could not tell you exactly what type of service it presently carries. It is upgradable to a considerable extent in any case.
We are planning to move to VOIP as an adjunct to this project. This is secondary to getting the fax system moved but we would like to avoid having to install additional hardware for VOIP once the fax portion of project is complete and the service transferred.
What are our options?
