    Seems like WRV200 has problem with SIP (latest .20 version).

    My PAP2T tries initiating session, vbuzzer.com responds, and WRV200 sends back ICMP reply 'destination unreachable. I've seen it with EtheReal tapping in between router and DSL modem.

    AFAIK, there's a feature called UDP hole punching which seems not to be working. Any ideas if it's a bug or security feature? Any workarounds?

    You may need to forward some ports for your SIP device to work.

    It did not require any static forwarding with any routers I used before.

    And after all, that was only a control session for registering.

    How I'm supposed to make static forwarding for RTP sessions with high UDP numbers? They are dynamic.
