Two VOIP services, one DD-WRT?

    Hey all.

    I have VOIP from LINGO now.
    My company gets a deal from Vonage. So I was thinking of trying the Vonage thing out for a while.

    How would I configure the router to work properly with TWO voip services??

    Unless you HAVE to forward ports for one of them, the two should coexist nicely. I have my Vonage adapter behind a WRT54G with no ports specifically forwarded, no DMZ, and no port triggering, and it works fine.

    The Vonage adapters (at least the newer ones) just want open ports, not forwarded ones.

    If LINGO requires that the SIP port (5061) be forwarded, then you simply forward that port to Vonage for a while, hook up the Vonage adapter, and call Customer Service and tell them to change the default port. Vonage uses the standard SIP port (5061) for server comm, then selects a random port between 10000 and 20000 to make the actual phone call connections.

    If LINGO doesn't require that 5061 be forwarded, just open, then Vonage should coexist with it just fine as far as I know. I know several people on the Vonage Forum ( www.vonage-forum.com ) are using multiple Vonage lines with no problems.
