    Hi,

    I am trying to set up the 3CX pbx to work with a Draytek 3300V router which has 4 FXO ports, three of which are in use with a BT line plugged in to each.

    I have configured 3CX to use these ports, using Add PSTN and the Generic Gateway setting. I set separate ones up for each line, rather than settin up a single entry with three ports, as the BT lines are all separate and have different numbers.

    I delved through the quagmire that is Draytek documentation and have managed to configure the 3300V so that incoming calls to the BT line that is plugged into one of the FXO ports are answered, passed to 3CX, and transferred to a (softphone) extension. This all seems to work fine, bar a slight burst of dialtone which may be a little disconcerting to callers.

    However I can't for the life of me get it to dial out and make calls over the BT lines. A sample log from 3CX is as follows:
    12:54:05.203 Call::Terminate [CM503008]: Call(38): Call is terminated
    12:54:05.187 Call::RouteFailed [CM503014]: Call(38): Attempt to reach [sip:07967******@192.168.0.23] failed. Reason: Not Found
    12:54:05.171 CallLeg::eek:nFailure [CM503003]: Call(38): Call to sip:07967******@192.168.0.1:5061 has failed; Cause: 404 Not Found; from IP:192.168.0.1:5061
    12:54:05.000 CallCtrl::eek:nSelectRouteReq [CM503004]: Call(38): Calling: PSTNline:10001@[Dev:sip:10001@192.168.0.1:5061]
    12:54:04.984 CallCtrl::eek:nIncomingCall [CM503001]: Call(38): Incoming call from Ext.101 to [sip:07967******@192.168.0.23]

    As I understand it that indicates that 3CX is receiving the call from the extension, understands that it should be made over the PSTN line, and asks the router at 192.168.0.1 to place that call, but the router is responding with 404 not found. Presumably then this is a problem either with the way that 3CX is making the request to the router (should it be something other than phonenumber@routerip?) or with the way that the router is configured.

    Since there aren't details given for how to set up the FXO gateway on the draytek correctly, I've tried what must be every combination under the sun based on the 3CX instructions for other models, but to no avail. Is there anyone who could give me some guidance on this, as not really understanding what is _supposed_ to happen I'm finding it very hard to work out what i should set and where!

    I can easily post screenshots of the draytek FXO configuration settings page if that's likely to be any help.

    Many thanks,

    Harry

    Did you get any joy with this? Considering a Darytek 2820s (ISDN2 Model)
