[Serusers] SER 0.9.3 crashing on Solaris 10 (sparc 64bit) server

by lists

Hi, I have migrated my SER proxy from Linux servers to Sun Solaris 10 (sparc 64 bit). Same SER version (0.9.3) and config file work perfectly fine under Linux and now its crashing. Every time SER needs to fork of a new branch (append_branch();) it core dumps. any idea why this would be happening? thanks fil here is the portion of ser.cfg which is crashing: failure_route[4] { log (1, "**************** FAILURE_ROUTE[4] CALLING VOICEMAIL\n"); # forward to voicemail now if (isflagset(4)){ rewritehostport("192.168.0.5:5060"); append_branch(); route(1); }; } here is the the SER startup with debuging set: 0(17715) failure routing table 4: 0(17715) log( 0(17715) 1 0(17715) , "**************** FAILURE_ROUTE[4] CALLING VOICEMAIL " 0(17715) ); 0(17715) if ( 0(17715) isflagset( 0(17715) 4 0(17715) ); 0(17715) isflagset( 0(17715) 4 0(17715) ); 0(17715) ) { 0(17715) sethostport( 0(17715) "192.168.0.5:5060" 0(17715) ); 0(17715) append_branch( 0(17715) Segmentation fault here is the output of gdb run: gdb -c /var/core/core.ser.17722 /usr/local/sbin/ser GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.

[Serusers] Radius question

by Alberto Cruz

Hi guys, I have a doubt. Is it possible to use radius related modules with out using db related modules at all? Which are going to be the side effects If I don't use db modules? For example I tried to load mediaproxy module and it is claiming for commands like "is_uri_host_local()" or "is_from_local()" in order to be load it but these commands are only available if I load the db modules. Who can help me to clarify the relationship between radius modules, mediaproxy module and db modules? Regards Alberto Cruz

[Serusers] serweb add user

by Olivier Roomans

Hi, I would like to ask a small question about serweb : how can I use it to add new users ? I've done some research on the ml archive but didn't find clear information about that (some people where talking about sending an email but I'm not really sure). Thanks in advance.

[Serusers] Use of fifo for registration :ul_add: command tutorial

by Rodrigue ESTEVE

Hi all, I would like to use ser_fifo to register a user; I think the :ul_add: command is the clue, but I don't how to use the fifo to do this. My aim is to do the following: I have a Voip gateway on a customer with a lot of phone number (700) and I would like to authenticate each number. Unfortunately I have to add a small amount of configuration on the voip gateway each time I add a number (uri), moreover I'm not sure this gateway will work with so many numbers, and the bandwidth needed to register each number every 5 minutes will be wasted. The idea is to challenge only one time the gateway and then in ser.cfg if the challenge succeeds I execute a script to register by bulk all the numbers enclosed in a file on the proxy. To do this I have to pass arguments to the fifo using the :ul_add: command, but this is where I'm stuck. I've done this: echo :ul_add:receiving_fifo > /tmp/ser_fifo echo location > /tmp/ser_fifo echo 100 > /tmp/ser_fifo echo <sip:100@10.1.1.1:5060> > /tmp/ser_fifo echo 300 > /tmp/ser_fifo echo 0 > /tmp/ser_fifo echo 2 > /tmp/ser_fifo but it does not work, I think this is due to the receiving_fifo, I have to do something with it to process the response of SER, but what ?? I know I can use the following command to workaround the pbm: Serctl fifo ul_add location ... But it requires one process each time I register a number, and it takes 1 minute on a Celeron 700 for 500 numbers (30 % CPU), and I think using the fifo is a more suitable solution (less CPU consuming). Thanks for your support, Rodrigue PS: I would like to register every 5minutes,cause the customer gateway is able to redirect to PSTN in case of failure.

[Serusers] 'subst' on multiple lines - wackiness (and possible bug ensues?

by Kanakatti Mahesh Subramanya

I'm using 'subst' in multiline mode - basically using it to rewrite a 'Refer-To' header based on the contents of the 'Contact' header. However, if I do that, it looks like all the default processing that occurs on the message (specifically, the addition of a 'Via' header), gets tacked on to the end of the message. It almost looks like all the changes that were made to the message end up in a buffer that gets appended to the end of the message, and *not* as part of the message. In the example below, I just used the following to generate the error condition subst('/(.*)5100(.*)/\15100aptela\2/si'); And yes, I know that the above doesnt need the 's' flag. Its just that i've distilled my ridiculously complex 'subst' expressiond down to the above really simple expression which still causes the error below. So, the question is, is this actually supposed to work? Anyone ever actually tried this out? e.g. incoming packet is (note that th "Refer-To" line sez 'sip:5100@...'. This will get changed to sip:5100aptela@...

[Serusers] can't establish calls whenever using outbound proxy

by jeff kwong

Hi again! I used the nathelper.cfg from the cvs to use ser as an outbound proxy with rtpproxy. I commented out some parts which I thought I would not be needing. rtpproxy is working fine as well as ser. I placed my outbound proxy with a public ip and two ipphones behind nat. The phones were able to register, however whenever I call one using the other ipphone, my request timeouts and I get a busy signal. However, when i place one ipphone to the public and the other still behind nat. I was able to recieve a ring, calling from the nated to the public. And when both phones are in public, thus bypassing the outbond proxy, my calls go perfectly through. When i checked the dumps at the outbound proxy, it seems the soft switch does not return an "ok signal " or anything at all after recieving an invite with authentication, that is whenever using an OP. Are these symptoms familiar to anybody here? Any help would be most welcome. Btw I posted my ser.cfg file here just in case. # # $Id: nathelper.cfg,v 1.1 2003/11/10 14:15:36 janakj Exp $ # # simple quick-start config script including nathelper support # This default script includes nathelper support.
