Title: Re: RE: How to manage multi-calls use the dum objects.

You need to store AppDialogSet pointers (which give you access to InviteSessionHandles) or the InviteSessionHandles for each call.

You could check out the new recon library as a sample.

Hello:

I read the the document you offered, but I still can not understand how to use the AppDialog/AppDialogSets objects to control the multi-calls.

For example, at first, I created the call one, and then I created the call two.
Then I try to handup the call one, how to implement this ??
If I call the InviteSessionHandler->end(), it can only end the call two. How to switch the context to the call one ??

Is there have some example for controlling the multi-calls with dialogsets?? Very thanks!!

        You only need one stack and one dum object.  You can use AppDialog/AppDialogSets to help differentiate between two different calls:

                Hi Scott:

                I want to design a softphone which can maitain a few calls(more than one) at the same time.

        For example, I hold an active call and accept another new incoming call.

                But I don't know that how much objects(dum,sip stacks,invite handler,register handler) I need to bind with the sip calls.

                In the beginning, I use one dum object in every call object, but I found that its waste of resource. And another problem is that the multi-dum objects can not be created at the same port(5060) by the dum::addTransport(UDP, 5060) function.

                        Questions:

        1.If the only one dum object can maintain multi-calls at the same time ?? I'm very confused about this.

                        2.If one dum object can not manage multi-calls, I want to know the best way to maintain multi-calls at the same time with the resiprocate library ?

                        Very thanks!!!
