I switched from POTS to all-VOIP but just found out that my security system can't seem to dial through the VFX service. I have a Linksys PAP2T. The phone line is wired through the security system to the Linksys adapter to enable it to "catch" the line before any other telephone. My regular phone works with no issues (routed through the security system) but the dialer from the security system seems less successful. Are there any known solutions to the problem? I'd hate to have to go back to Telecom...
