I'm using Teliax VoIP with a Linksys PAP2-NA phone adapter. I've read the troubleshooting for the phone adapter and IVM Answering Attendant but I haven't found a solution. Everything seems to work just fine through the call simulator. With actual calls IVM appears to be working with the exception of not hearing or being heard. As I make test calls into the system I see that it says it's playing the correct file and if I select a menu item (without hearing the prompt) that also works for transfering a call but it does not "hear" a message being left in a mailbox nor can I hear the OGM's. It's clear that if I can get through this frustrating road block the software seams ideal for what I need. Any help would be greatly appreciated.
