Hi,

   I set a sip service from a sip vendor.  For any PSTN call to 1800-number, that sip vendor will forward to 1800-number@my.domain.   This domain is the freeswitch instance I set to forward to a local phone number.   When I test it  --- make PSTN call to 1800-number, I see the sip vendor sends sip request, but freeswitch log file shows  this message:  

sofia_reg.c:558 sofia_reg_handle_register() send challange for [18669304954@208.74.66.11]   

 208.74.66.11 is freeswitch ip

even if I set acl.conf.xml

    <list name="strict" default="deny">
      <node type="allow" cidr="<sip_vendor_ip_address>/32"/>
    </list>


How to configure it?


Thanks,


Stanley
