Hi guys i got a job to do w/a policom,the customer wants this policom active but they dont used analog ports in the system,of course i told them to get a analog card,but they dont wanted because is only a single phone and also they dont want a pot line just for the policom,so they asked me if was possible to connect to a regular digital phone(m3903),and i know in norstar systems they use a ATA adpter to convert digital to analog,so is anyone knows how to do this,thanks for the help I forgot to tell you this is opt 11c.
