Registration

Number of registered users in Cache are more than actual number of users on Registrar.

Looking at traces, I see user registers and its information is cache on SBC and Registrar.

After 15 minutes when Registration has expired, Client sends new Registration request which is challenged with 401. But client does not send authentication thus Registration process does not complete.

 

But same user still appears to be Registered in SBC Cache. Is there a mechanism where SBC keep the cache for last registered user even after sending 401 message (part of maintaining trusted que)

Currently cache expiry is set to 500 seconds

 

Thanks
