FreeSWITCH Version 1.0.7 (hacked-20110119T213949Z)

I have a freeswitch installed for testing. It just up for about an hour and there are two Cisco 7960 phones registered. After made several test calls between these two Cisco phones, FS stop working and give me these message on fs_cli:
2011-02-11 17:39:58.691008 [CRIT] switch_core_session.c:1629 The system cannot create any sessions at this time.

In the SIP header it shows: 503 Maximum Calls In Progress

What should I do to fix this? Here is the message by press F2, F3 and F4:
freeswitch at internal> status
UP 0 years, 0 days, 1 hour, 12 minutes, 55 seconds, 590 milliseconds, 20 microseconds
