    I would like to pass some voip traffic through an isp which is blocking voip traffic
    the solution would be a vpn
    I am looking for a pair of router which can do this for me
    must be very easy to configure , must be flexible on port.must support some sort of dydns service (any)

    I have used dd-wrt on my linksys but it drops from time to time nor does the pptp section allow me to use alternate ports

    I am not looking to spend alot of money (I prefer under 300)

    please advice me as to what is out there

    I don't understand why or even how an ISP would block VOiP. Are you sure? I'd be dumping that ISP without fanfare.

    VPNs in general are not the easiest things to setup properly but matching VPN routers make it pretty easy. Making your VOiP units go over the VPN and out the other end over to internet is really tricky. I can't give you simple methods for doing that. The best way in this case is to point the VOiP units to a PBX that is at the other end of the VPN. That itself is not too hard if you have an off the shelf PBX unit which will then go over your budget. You can build it yourself for $0 but then the tech factor goes way up.

    From an isp level it is very easy, usually blocking just SIP will take care of it, but some vendors are going other routes to bypass isp's that do this, so isp's can also block H.323 which cant be gotten around.

    Agreed, and it's made even more complicated and sometimes impossible by using devices that are not designed specifically to do this. If you decide to go that route, make sure you stick with the likes of Enterprise vendors that have platforms in place that already do this. Cisco and Juniper come to mind but there are plenty of them out there.
