Hi, It's a fresh install with wget freeswitch.org/eg/Makefile && make, and I'm sure I successfully called 9196 and everything was ok. But a few minutes later I started getting 503 Maximum Calls In Progress also originate user/1003 or loopback/9196 shows errors see http://pastebin.freeswitch.org/15333 It's on a ubuntu 8.04 32bit, the only thing I did between non-work and work was I configured odbc with postgresql to work with isql. I haven't touch the FS config yet. I don't think they are related. here is also a nua debug http://pastebin.freeswitch.org/15335 Any hint on this? Thanks. btw, I also noticed there might be some network problems between me and the server where sometime sip packets not shown ( sofia debug and ngrep) on server. Anyway, since loopback cannot create sessions so something must be wrong in FS side, but what's that? Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn
