Hi,

Sometimes I got calls terminated in 34 seconds.
Acc sql dump for normal call:
| 573379090 | 2007-06-13 14:01:37 | INVITE     |
| 573379090 | 2007-06-13 14:01:37 | ACK        |
| 573379090 | 2007-06-13 14:02:04 | BYE        |

And calls, terminated abnormal:
| 573379090 | 2007-06-20 20:37:56 | INVITE     |
| 573379090 | 2007-06-20 20:38:56 | INVITE     |
| 573379090 | 2007-06-20 20:39:59 | INVITE     |
| 573379090 | 2007-06-20 20:40:59 | INVITE     |
| 573379090 | 2007-06-20 20:42:46 | INVITE     |

| 7631081  | 2007-06-20 20:38:31 | BYE        |
| 7631081  | 2007-06-20 20:39:30 | BYE        |
| 7631081  | 2007-06-20 20:40:33 | BYE        |
| 7631081  | 2007-06-20 20:41:33 | BYE        |
| 7631081  | 2007-06-20 20:43:20 | BYE        |

So, SER lost ACKs.
Problem appear and disapper randomly.
Config is based on nat-rtpproxy.cfg and gw-pstn.cfg
Any idea?
