[Users] tm-module status rewrite
by Andreas Granig 27 Jun '06

27 Jun '06

Hi, Under heavy load, I sometimes get log messages like these: ERROR:tm:t_should_relay_response: status rewrite by UAS: stored: 408, received: 100 ERROR:tm:t_should_relay_response: status rewrite by UAS: stored: 408, received: 180 It doesn't seem to be critical because the calls are established successfully, so is this really an error? If not, can we decrease the log priority or even only print it in debug mode? Andy

I second that. It would definitely be nice.

[Serusers] P-Asserted-Identity

The test is against regulatory bodies in some countries that allow only certain CLIs to be presented. IMSs is step farther away in the pipeline Adrian ///////// Hi Dani, Im not entirely sure about that random number problem you are trying to solve, but I think it's not currently possible. You may try looking into avops module though... Yet I have another couple of questions: 1. Are you trying to test an IMS platform? 2. If, yes, then which one? Andrey.

[Users] isdsturiset
by OpenSer Users 27 Jun '06

27 Jun '06

hello, I am interested to know if I can test for the IP address ot the "next hoop" after loose_route(). I see that isdsturiset() does not take any parameter. for the moment I use something like if(search("^Route:.*IP_ADDRESS_TO_SEARCH_FOR.*") { ... do something here ... } is there an another, nicer, way to do this ? thanks, razvan radu

[Users] Openser password change
by Kenny Chua 27 Jun '06

27 Jun '06

Hello everybody, Have anyone of you changed the openser and openserro password? I've actually changed it in mysql. And then of course changed it in my openser.cfg. However after that, everything just fell apart. What else am I missing? If I do change those 2 passwords, where else am I suppose to change it? Another question is, have anyone of you ever had the problem where openser just don't want to start. I've found out it's not starting whenever I typed openserctl moni or ps. It tells me openser_fifo not found. Then I use monit to restart it. Still nothing happens. Created a fake openser_fifo in /tmp, still nothing worked. After awhile of leaving it on, openser finally decides to start. Not sure what triggered it. This problem just happens sometimes. My system is, CentOS 4.3, openser 1.0.1, rtpproxy, monit 4.8.1. Thank you. --------------------------------- Ring'em or ping'em. Make PC-to-phone calls as low as 1¢/min with Yahoo! Messenger with Voice.
