Hi all, I've compiled the freeswitch with libpri support. But when I execute oz libpri debug 1 all, I got the following error. API CALL [oz(libpri debug 1 all )] output: src/ozmod/ozmod_libpri/ozmod_libpri.c: -ERR invalid span. Here is my openzap configurations. openzap.conf [span zt PRI_1] trunk_type => e1 b-channel => 1:1-15 d-channel=> 1:16 b-channel => 1:17-31 openzap.conf.xml <configuration name="openzap.conf" description="OpenZAP Configuration"> <settings> <param name="debug" value="9"/> </settings> <pri_spans> <span id="1" name="PRI_1"> <param name="q921loglevel" value="alert"/> <param name="q931loglevel" value="alert"/> <param name="mode" value="user"/> <param name="dialect" value="q931"/> <param name="dialplan" value="XML"/> <param name="context" value="default"/> </span> </pri_spans> </configuration> I feel something I've missed in configurations. Please tell me how to get rid of that error.
