Hi there.
I have the following scheme.
1. SIP server is running kamailio with module "acc", radiusclient-ng and freeradius. 2. DB server with MSSQL.
The problem is the following, if the connection is lost with the database, no one can make calls. Even after the connection to the database is restored. We have to restart the radius and kamailio. And only after that can make calls.
Kamailio logs
rc_send_server: no reply from RADIUS server localhost: 1813 ERROR: acc [acc.c: 720]: acc_rad_request (): radius-ing failed
Radius logs.
Error: rlm_sql_unixodbc: SQL down 08S01 [unixODBC] [FreeTDS] [SQL Server] Write to the server failed
