One way audio

[econst]

Hi all,
Here is the scenario. I have an account with Vonage and another with GalaxyVoice. My ISP blocks Voip so I use a VPN service to connect my routers to. My ATAs are then connected to the router. I have two types of VPN connections, one a SSl based VPN and the other a L2TP based VPN. The Vonage adapter works well when connected through either type of VPN. My GalaxyVoice adapter works well when I connect through the L2TP VPN, but I don't have audio in either direction on inbound calls, when connected through the SSL based VPN. My tests have detemined that the problem with some incompatibility for the GalaxyVoice ATA when connected through the SSL VPN, since the Vonage ATA works well through the same SSL VPN. The vonage adapter is a PAP2 and GalaxyVoice adapter is PAP2T-NA. Any ideas what would ne causing this? In other words, why would it work with a L2TP tunnel and only work one way when using the SSL tunnel?

I am still trying to figure this one out. I have verified that my adapter is sending and receiving RTP packets on inbound calls through the SSL VPN, but am still not getting audio. Any ideas?
