Python: Call class

[ktx@xxxxxxxxx (ktx at matfyz.cz)]

Hi,

I am trying to automatically hangup calls witch return redirect codes. It
works except for the end :)
->
$ python ex.py sip:somebody at somewhere.org
 19:42:20.622 os_core_unix.c  pjlib 1.6 for POSIX initialized
 19:42:20.623 sip_endpoint.c  Creating endpoint instance...
 19:42:20.624          pjlib  select() I/O Queue created (0x81e87c0)
 19:42:20.624 sip_endpoint.c  Module "mod-msg-print" registered
 19:42:20.624 sip_transport.  Transport manager created.
hanging up
disco
python: ../src/pjsua-lib/pjsua_call.c:1346: pjsua_call_get_user_data:
Assertion `call_id>=0 && call_id<(int)pjsua_var.ua_cfg.max_calls' failed.
Abort

1) How can i get rid of the debug messages?
2) Should I recompile with some less verbose settings?  But more
important: what is wrong with the code (see attachment)? I just
copied and combined the lines from the examples.
3) Can I somehow wait in the main thread until the end of call
(maybe lock)?

Thanks,
Karol
