[Serusers] conncection problem with idle server
by Felix Schmid 10 Sep '03

10 Sep '03

Hi, I got a problem with ser when it's been idle for a while. Any request sent to it is answered with SIP/2.0 500 I'm terribly sorry, server error occured (7/TM)..Via Syslog says this: Sep 10 16:18:41 gurke ser[65803]: ERROR: get_out_socket: no socket found Sep 10 16:18:41 gurke ser[65803]: ERROR: add_uac: can't fwd to af 2, proto 1 (no corresponding listening socket) Sep 10 16:18:41 gurke ser[65803]: ERROR: t_forward_nonack: failure to add branches Sep 10 16:18:58 gurke ser[65809]: BUG: tcp_main_loop: dead child 1 Ser runs on freebsd4.8 here. Any suggestions what could be the reason for this? Why is it complaining about problems with tcp? I thought that sip is udp-based (though I know that latest version of ser supports tcp connections also)? regards, felix -- PGP-Key: http://belugalounge.net/~felix/Felix%20Schmid.asc

RE: [Serusers] Implementing Voicemail
by Steve Dolloff 10 Sep '03

I'm sure this is pretty straightforward to some of you, but I could use some help with a few issues if someone has the time. Below is my config file. This is running on RedHat 9. I am having numerous problems. 1) Having issues with correctly increasing the number of children. If I increase it, it fails because it can't connect with mysql. I have tried increasing the number of connections in mysql in the my.cnf file, but it seems to cause even more problems. 2) I only want the call to fail to route 2 for calls that terminate in my network. I don't want calls leaving the network to try to go to voicemail after the time hits. 3) I can't seem to figure out how to format the rewrite/append/etc to trigger the voicemail call. Maybe I don't understand the routing loop. Can someone take a look at the config and give me some ideas? 4) The append to the null/parallel destination that allows the trigger to activate I don't understand at all. Why does it need to be there? Where should it be pointed to? 5) I'm not seeing the activity/routing logs going anywhere. If I run ser manually, I see information on the stderr, but nothing in the database or logs in terms of the connections. I would really appreciate any help. I have other questions that aren't related to the configuration file, so I will save those to amuse people later.

The closest example is at http://www.iptel.org/ser/doc/seruser/seruser.html#REPLYPROCESSING There is no number of rings in SIP -- there is the invite_fr timeout. -Jiri

[Serusers] cisco 7960 authentication failure
by Jakob Schlyter 10 Sep '03

10 Sep '03

hi, I'm trying to use www_authorize/www_challenge (ser 0.8.11/solaris) together with my cisco 7960 (auth backend is mysql and calculate_ha1=1). when I reach www_authorize (with, as I believe, proper authorization) I get the following error message: pre_auth(): Credentials received are not filled properly sent to client: WWW-Authenticate: Digest realm="zettou.net", nonce="3f5e52fd5db948e3b493525f89fe24bfd0f86d9e", qop="auth" sent from client: Authorization: Digest username="jakob(a)schlyter.net", realm="zettou.net",uri="sip:schlyter.net", response="8503ab9b93e73ef0033d0e265f31dd0f", nonce="3f5e52fd5db948e3b493525f89fe24bfd0f86d9e", cnonce="718436df",qop=auth,nc=00000001,algorithm=md5 what have I done wrong? jakob

Re: [Serusers] SER in combination with a H.323 GK
by jaime.gil＠orange.co.uk 10 Sep '03

Wouter, If you want to try with an opensource SIP-H.323 Gateway, there is Vovida's siph323csgw. It is not the most stable software in the world and not well maintained. However, it makes the trick to call from H.323 to SIP clients (we tried Netmeeting and MSN) and viceversa (you will need to restart it several times, though). There are commercial implementations, like RADVISION, that might help you much more on this.

This works great if the user is offline. Is there anyway for voicemail to pick up after a certain time period or after a certain number of rings?

[Serusers] SER in combination with a H.323 GK
by Wouter Prins 09 Sep '03

Hello, Is it somehow possible to let SER communicate with a H.323 gatekeeper like openh323's gnugk or some other gatekeeper software? I have been searching for documentation but couldnt find much, perhaps someone can point me in the right direction? Thanks in advance! Kind regards, Wouter Prins

I have the sems installed and it works great. Does anyone have a config that they could share that would illustrate how to use the vm in normal use? I'm sending all off-net calls to a sip gateway. I would want calls to go to vm after x rings.
