Problem with Voxaloy and Sipgate when using PAP2T
 

I have a number of sipgate accounts registered to my voxalot account which I use for incoming calls. I also have a voipstunt account regsitered for outbound calls.
Whilst I am aware of the issues with Betamax, this still seems to be working for me.
I have my PAP2T set up behind a NAT firewall and until the other day everything was working fine. Now I cannot receive calls through the linksys. The phone rings and I can answer it, but I hear nothing and after a few seonds it just beeps.
I have set up one of the sipgate accounts directly onto the linksys (instead of voxalot) and it works fine. Its only when I go via voxalot. I have set up x-lite on my PC to test and the voxalot service seems to run fine through that.

Does anyone have any ideas what could be wrong with my setup?

On a side note...can anyone recommend a TA that can handle multiple providers? i.e. use voxalot to handle most stuff and the TA to handle to betamax stuff?

Thanks in advance

Dave.
