Hello All,
I noticed in one of your previous reply (below), you recommend delaying 500
milliseconds between mulitiple registrations. Why is this necessary?
I'm asking this because nua_create() is failing in the following scenario:
1) nua_create() (port 5061)
2) Register Line
3) Unregister Line
4) Shutdown Line
5) nua_create() (port 5061)
.......... nua_create() returns zero................
6) Re-register Line
However, if I place a 500 millisecond delay between steps 4 and 5, then the
process completes succesfully.
Best Regards,
Jerry

The su_root_run() handles only the stuff inside one process.
Just create all your nua objects in a single process and after that
call su_root_run(). Perhaps you could also delay calling
nua_register() for each UA with su_timer_t so all the UAs do not try
to register themselves at the same time. Write a function calling
nua_register(), give it to su_timer_create() with a pointer to a
struct with a pointer to nua object and related data, then call
su_timer_set() with suitable delay (give 500 milliseconds between
registrations).
If your media handling works better with separate processes, I think
you have to fork before calling su_create_root(). You could also have
a master process that wait()s for its children to die (and launches
again all the failed kids, perhaps also with some kind of delay
between fork()s and checks for a child process dying repeatedly.)
