My FS server was working fine until (suddenly) now.
When I want to call a mobile phone (via a gateway) I get busy (?) or unavailable (?) and get this message:

freeswitch@internal> 2011-06-18 19:23:00.379259 [CRIT] sofia.c:841 No more sessions allowed at this time.

There is only one user on my system. (myself)

Rgds.
Henk.
