Hi Khalid, We have tested with IMSBench in the past, so I think we should be able to get this working.
Looking at the information that you sent in your email, it looks like your SIP URIs don’t match – the bulk-provisioning is with 700000 but the IMS Bench input file is 7000000. This may be the cause of the 403. You should also be careful if you are using a Project Clearwater all-in-one image. The all-in-one node isn't really built for performance - it's just built to pack everything onto as small a node as possible - you may hit performance issues that you wouldn't hit on a full deployment. When we tested before, we hit an issue with IMSBench’s TCP support. Matt Williams dug out his notes from the time: The IMSBench tests require some special behavior from the implementation under test if using TCP transport. Specifically REGISTER requests from IMSBench specify a port number of 7001 in the Contact header, but the scripts then expect INVITE or MESSAGE requests on port 7000. (We believe this behavior is required to work around a limitation of SIPp where a single script must either act as a UAC or a UAS, so you cannot write a script that issues a REGISTER then wait for an incoming INVITE or MESSAGE. IMSBench has therefore separated these two phases in to different scripts which cannot share the same port number.) The work-around for this (dating back to 2013) is at https://github.com/Metaswitch/sprout/tree/imsbench-interop (and doesn't currently merge). UDP transport might be a better bet, although I don't know whether we tested that. I hope that helps.

I need a bit of help about the whole thing specially regarding the scenario files used by ims bench. I have tried to run the benchmark with the default scenario files generated by ims bench but the test fails. Do I need to change the default scenario files for clearwater in some specific way? I have bulk provisioned 4000 subscribers ([email protected]<mailto:[email protected]> - [email protected]<mailto:[email protected]>) and checked they exist in homestead and made a test call with one of the subscriber. The format of the generated users.csv file for bulk subscriber in clearwater is: sip:[email protected]<mailto:sip%[email protected]>,[email protected]<mailto:[email protected]>,example.com<http://example.com>,7kkzTyGW sip:[email protected]<mailto:sip%[email protected]>,[email protected]<mailto:[email protected]>,example.com<http://example.com>,7kkzTyGW ... The format of the user input file for ims bench is like following: 0;7000000;example.com<http://example.com>;7000000;example.com<http://example.com>;7kkzTyGW 0;7000001;example.com<http://example.com>;7000001;example.com<http://example.com>;7kkzTyGW ... ... I tried only with the registration scenario but it fails. The error log in ims bench looks like: 2016-05-27 02:31:21.116: C:'[email protected]<mailto:C%3A%[email protected]>' UNEXP-Jump(2) L=9 expecting '401' rsp, rcv 'SIP/2.0 403 Forbidden Via: SIP/2.0/UDP 192.168.180.139:9451;received=192.168.180.139;branch=z9hG4bK-3001-231-2 Call-ID: [email protected]<mailto:[email protected]> From: "sip:702451" <sip:sip:[email protected]<mailto:sip%3asip%[email protected]>>;tag=231 To: "sip:702451" <sip:sip:[email protected]<mailto:sip%3asip%[email protected]>>;tag=z9hG4bKPjmxnDFiTr4nth4Jd-L2wKosanDPQGP8iS CSeq: 1 REGISTER Content-Length: 0 I have also attached the registration scenario file that I'm using. It would be nice if someone knows something or did a similar test before please let me know. It would be nice if you can guide me a bit or share a sample scenario file that would with clearwater and ims bench. Thanks all in advance. Best, Khalid
