[reSIProcate-users] How to manage multi-calls use the dum objects.

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!!!
