Hello, I've hit a wall with my sipp scenarios and I figured the sipp community could point me in the right direction.
Here's what I am trying to accomplish: I am using SIPP to generate 1000's of simultaneous g729 media calls, and I want each simulated call to look like it's coming from a 199 plus random 8 digit phone number in the "From:" header (for example: sip: 19912345...@[local_ip]). I've tried to accomplish this by creating an injection csv file that is pasted below: ---------------------------- rand_caller_id.csv: RANDOM,PRINTF=89999999,PRINTFOFFSET=10000000 199%03d -------------------------- ...Which gets injected into the INVITE packet like so: From: [field0] <sip:[fiel...@[local_ip]:[local_port]>;tag=[call_number] This does generate the appropriate numbers, and it does inject them in a random sequence, but the sequence is always the same. It seems like the random seed doesn't change. The reason this is a problem is that I am actually running different SIPP processes simultaneously in order to reach the level of calls that I want, and to add diversity to the simulated calls. The whole point of trying to create random "caller" phone numbers is so that each simulated call looks like it's coming from a different caller to our system. (We use the "199" at the beginning to flag that this is not a real phone call). I would like to find a way to either "re-seed" the randomness of the Injection File every time SIPP runs, or use some other method to insert 8 random numbers after 199 in my INVITE packet's From: header. Any thoughts? Hopefully this can be done on the command line or scenario level. I am not a C programmer so I would need some hand- holding if I need to revise source code :) Here's the stats on the server, in case that's useful: SIPP 3.1 Linux CentOS 5.2 x64 8 Core Intel Xeon 2.33GHz Thanks, Chris ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Sipp-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sipp-users
