I think the constraint is in sipXmediaFactoryImpl.cpp as
#define MAX_MANAGED_FLOW_GRAPHS 16

I have just made 16 simultaneous calls using my client, so its not
really 10. When trying to make 17th simultaneous call, it gets blocked
somewhere.
If you look into call manager, you will see it just means that if there
are more than 10 calls, it will send a BUSY_HERE SIP (486) message back
to the sender on inbound call.
I'm planning to revamp the whole sipxtapi, introduce new parameters like
this.
