Hi Moritz, The error log you posted says: 2014-01-20 11:17:57:194 1390213077.194807: Call-Id: 1-20926@1.2.3.4, receive timeout on message Test LCR:1 without label to jump to (ontimeout attribute): aborting call. 2014-01-20 11:17:57:195 1390213077.195609: Dead call 1-20926@1.2.3.4 (aborted at index 1), received 'SIP/2.0 302 Temporarely Moved'... What this means is: * at 11:17:57:194 SIPp decides it hasn't seen the 302 message in time, so it aborts the call * at 11:17:57:195 the 302 message arrives, but is ignored because the call has already failed Looking at your SIPp script, you've set timeout="1" on your <recv> element for the 302. This means that if the 302 message doesn't arrive within 1 millisecond, SIPp will fail the call. I expect what is happening is that, in the 199 out of 200 cases, the response is very fast and arrives in under a millisecond (and there might be a few milliseconds of grace in the SIPp scheduler). But some of the time, the response will take just more than a millisecond to arrive, and so you see logs like the above - where SIPp times the call out and the message arrives straight after. I recommend setting your timeout to a more reasonable value - 1 second (timeout="1000") should be plenty.
