That shows the other end is sending a RESTART command.
Can you make a trace of the debug log on the console or the logfile from mod_logfile showing the calls working and then on to when you get the issue including the several failed call attempts in their entirety and post them to http://jira.freeswitch.org under the openzap category.

I have moved your issue to http://jira.freeswitch.org/browse/OPENZAP-18
since it's an openzap issue and not a build system issue.

Please pay attention to the emails you receive regarding the issue and promptly reply to any comments.
