Many of our telecommuters use a Lucent/Avaya product called IP Softphone. This software is a poor man's VoIP in that it allows for redirection of calls from the local office PBX to your home phone and allows you to dial-out from your house as if you were in the office. Since converting to the Cisco VPN we have lost the ability to communicate with this software/PBX. Best I can tell the packets sent from the local machine are embedded with the ISP given IP address rather then VPN given, so the PBX is unable to talk with the local computer. We just converted from a Nortel VPN which seemed to overwrite your local computer network settings with the VPN given IP address etc. while connected. Is there any way to do this with the cisco or at least be able to fool the PBX??
