Dear all,

I want to force openser to ping all registered users with  OPTIONS message, my configuration as follow, flag in location table is 512 for sip_nat_flag, and 513 for NAT.  I can see the OPTIONS message send to the users and got replied for a few minutes, after that, it stop sending.   Is there something I’ve done wrong?  

Thanks

Ray
