Hi Bogdan, We upgraded to v0.8.14, and t_check_status works as you described, and perfectly for what we want to accomplish.

Re: [Serusers] SER dies when call reaches 12000

So, basically you can have as much active call as you want, without loading ser at all. anyhow, it's an impresiv number of parallel call.

I'm trying out this what looks like nice software while the kids are sleeping. I just installed 0.8.14 and I'm messing around with getting multiple domains to play. What is the correct way to update the table domain ? Just an INSERT directly into the database ?

[Serusers] Broken "SIP Aware" Router
by Andres 30 Jul '04

30 Jul '04

We have started having problems with customers in BellSouths ADSL network. New customers are being given the Westell ADSL modem which appears to be "SIP Aware". But the implementation is terribly broken. The symptoms are that SIP INVITES cannot penetrate the NAT on the Modem even though we have a permanent Keep-Alive from the inside (every 15 seconds). Furthermore when the customer tries to make a call, the modem changes the source port of every single packet of the dialog. Thus breaking the SIP dialog completely. Our interim solution was to setup these customer on an alternate server listening on a different port. For everybody's reference the modem version is: Westell B9061003006 and the Software is: 03.00.61 I have tried to contact Westell directly but they have not answered. I hope this is not something thats going to start happening with all modem manufacturers or else were going to have loads of trouble. -- Andres Network Admin http://www.telesip.net

[Serusers] SER dies when call reaches 12000
by Kenny Lam 30 Jul '04

30 Jul '04

Hi all, I have setup the SER with media proxy to deal with the problem of NAT. However, each time the number of calls reaches around 12000-15000, the SER will either doesn't accept call and increase failurerates or it will be down without any prior warnings. Anyone got the same experience before? I've tried using both CVS 8.12-1rc6 and rc5 before, both get the same problem. Thanks a lot!
