Hello, I have one FS instance that is working well with a PRI and running FS version 1.0.5pre9. Originally, it was running FS version 1.0.4 and I then upgraded it. Now, I am trying to bring up another FS instance (basically a clone of the first), but the PRI does not work. When I attempt to make an internal-to-PSTN call, I get a "502 Bad Gateway" reply. I verified that both servers are using the latest Sangoma Wanpipe driver, and I copied the conf XML file tree from the old server to the new one. I think the problem has to do with the openzap module, but I'm having difficulty isolating the problem. Could it have built the openzap module incorrectly? Another difference is that I installed 1.0.5pre9 from scratch on the new server (i.e. it never had 1.0.4 running on it). I put the FS log into the pastebin when an outbound call attempt is made: http://pastebin.freeswitch.org/11675 Could someone give me a pointer on what to try next? Thanks and Best Regards, Jerry
