Hi all, I met a problem which I thought is caused by the timeout config setting. I use SIPp UAC <-> FreeSWITCH <-> SIPp UAS to do my test. Commands: FS: ulimit -s 256; sudo ./freeswitch UAS: ulimit -s 256; sudo sipp -sn uas -i 10.67.7.224 10.67.7.46 -trace_err UAC: ulimit -s 256; sudo sipp -sn uac -i 10.67.7.213 10.67.7.29 -trace_err -l 5000 -m 5000 -d 300000 -r 5 Infr: UAC(10.67.7.213) <-> FS internal(10.67.7.29) FS external(10.67.7.46) <-> UAS 10.67.7.224 ********************** *** My problem **** ********************** I delayed uac for 300 seconds to send the BYE messages to uas, but after about 40 seconds of pausing, uas received BYE messages from FreeSWITCH: 2009-03-16 14:36:16:274 1237185376.274928: Aborting call on an unexpected BYE for call: 1-16380@10.67.7.213. **** Help *** Can anyone tell me how to release the timeout limit?
