Hello, * List of components with version:* OpenSIPS 1.5.3 notls call-control 2.0.6 CDRTool 6.9.5 FreeRADIUS 2.1.6
*Current setup:* The platform is implemented to have prepaid & postpaid billing support with prefix based routing using carrierroute. call-control & opensips are installed on the same server. CDRTool & FreeRADIUS are installed on the separate servers. For calls from or to postpaid accounts, we are not sending request to call-control. But when the account is prepaid, then opensips will send request to call-control to set call limitation. *Issue:* When there's more than 40 prepaid simultaneous calls, call-control introduces delay in processing requests from opensips, which leads to PDD more than 10 sec. As we set fr_timer to 10 seconds, opensips sends 408 Request Timeout. We debug opensips & call-control code for the whole flow. What we found is, call-control stores all requests from opensips to queue & processes it one by one. When there's more than 40 calls, the queue processing in call-control introduces delay. Btw CDRTool responds within less than half a second for each request from call-control. So we think there's something wrong with call-control, basically in queue processing. One more thing , we tried to upgrade call-control to 2.0.8 version. But it didn't resolve the issue. Is anybody there who can help us out to resolve the issue, we would appreciate the help. Regards, Krunal Patel
