Re: [reSIProcate] SDP Contents not getting created.....

[frank zhao <frankzhaohb@xxxxxxxxx>]

I think  you should call it like this:
    ...................................................
     sdp = new SdpContents(hfv, type);    <---- But this is the problem for me.
     sdp->checkParsed();
    ............................................

Because sdpArray is a local variable allocated on stack. On  leave
this function, the memory will be released. After called
sdp->checkParsed(), a memory will be created for sdp object on heap.
