[Freeswitch-users] Caller ID issue

I have been having a problem with my outgoing caller ID coming through as Private or Restricted using a PRI + Openzap. My provider claims that it must be a configuration on my end. Is there something I might be missing? Setup is essential the default FreeSWITCH configuration. I realize this is pretty vague, but I don't really know where to start to troubleshoot this issue on my end. Caller ID works from SIP UA to SIP UA as well as for all incoming calls. I don't even know where to configure FreeSWITCH to mask my caller ID as private or restricted. Thank-AF
