[reSIProcate] SUBSCRIBE callback?

["Dien Ba Quang" <dienbaquang@xxxxxxxxx>]

Hi,
I'm a new member of reSiprocate, I'm now developing a SIP softphone
using resiprocate as a SIP stack. I have problems with SUBSCRIBE call
back:
I can't get callback for SUBCRIBE (client) , below is my code:

        clientDum->addClientSubscriptionHandler("presence",&subListener);
        Data mevent("presence");
        int exp_time = 400;
        testAppDialogSet *uac = new testAppDialogSet(*(clientDum), 
"UAC(SUBSCRIBE)");
        SharedPtr<SipMessage> SubscribeMessage =
clientDum->makeSubscription(uasAor, mevent, exp_time, uac);
        //SubscribeMessage.header(h_Accepts).push_back( Mime( "application",
"simple-message-summary") );

        //SubscribeMessage.header(h_Event).value() = "presence";
        clientDum->send(SubscribeMessage);

Did I do something wrong? I used Ethereal to capture the packets:

X-lite soft phone
F1:      -----SUBSCRIBE ---------------->  | ----------------------------->

F3:

F4:       405 Method not allowed -------------------------------------->

Any help appreciated,
