[Serusers] Support for multiple PSTN Gateways (hunting, crank back)
by Frank Fischer 31 Aug '05

31 Aug '05

Hi all i have multiple gateway devices to PSTN. All are equal in terms of what destinations may be reached behind it or the termination costs. I use multiple devices for two reasons: capacity and failover. So what i need is functionality to hunt lines or at least doing a crank back (or even better both). The best way to this (IMHO) would be to track the line usage on each gateway and check it before routing to a gateway to make sure, there is a line available to place the call to (this … [View More]

[Serusers] Adding +1 to From:/To: for E.164 compliance
by Ryan Tucker 31 Aug '05

31 Aug '05

Greetings... We are starting to work with a carrier which requires From: and To: to be in E.164 format (e.g. +17005551212). prefix() only seems to change the INVITE, which doesn't appear to cut the mustard with these guys. Is there any way to make this happen within SER? Thanks! -rt -- Ryan S.

[Users] set timer for Request Timeout
by Jens Carl 31 Aug '05

31 Aug '05

Hello all, I have following records in the table 'usr_preferences': username attribute value 1000 fwdbusy sip:1001@example.de 1000 fwdnoanswer sip:1001@example.de I use these records to get the functionallity of "Call Forwarding - Busy" and "Call Forwarding - No Answer" into the OpenSer - server. I use a failure_route to act on the SIP - messages "Request Timeout (408)" and "Busy(486)" and forward the INVITE - message to the URI saved in the table 'usr_preferences'. See my snippet of the … [View More]

[Serusers] Error using TCP
by Federico Giannici 31 Aug '05

31 Aug '05

I'm using SER 0.9.3 with OpenBSD 3.7 amd64. Everything works correctly if I use normal UDP connections. Now I have to use a TCP connection (UDP is blocked in that network). Using ngrep I see SER receives the requests ma no reply is sent. The following errors are logged: Aug 23 12:48:06 eowyn /usr/local/sbin/ser[16406]: ERROR: send_fd: sendmsg failed on 19: Invalid argument Aug 23 12:48:06 eowyn /usr/local/sbin/ser[16406]: ERROR: send2child: send_fd failed Aug 23 12:48:06 eowyn /usr/local/… [View More]

[Users] Combining AVPs
by Martin Kjeldsen 31 Aug '05

31 Aug '05

Hi Can anyone offer some helps on how to combine multiple AVPs. What I would like to do is to create an uri (eg. sip:bob@biloxi.com), where the "bob" part have been taken from e.g. the username column in the alias table and the rest either prefixed/appended from some static data or grabbed from another tuple! Can anyone offer some insight as to how this may best be accomplished. -- Med venlig hilsen / Kind Regards Martin Kjeldsen Cuatro-Group P/S (4G) Hindegade 3, DK-1303 København K … [View More]

[Serusers] NATHelper IPv4-IPv6
by Ahmed Kellal 31 Aug '05

31 Aug '05

Hello everyone, I am working on setting up a heterogeneous platform with both IPv4 and IPv6 UAs. Problem I am facing right now is that I need to add a little to the code, in order to: 1- Extract the hostname part of the Contact header field, when needed 2- Change the said hostname contact 3- Extract the IP (v4 or v6) address in the owner ("o=") field of the SDP body 4- Change it with the value the RTP Proxy assigns dynamically to represent an IPv4 UA in the IPv6 world and vice versa In … [View More]order to do these things, I tried to understand as much as I can of the code of the NAtHelper module. I wrote four functions to do the above, but (naturally enough in my case :-)) they're not doing what I want them to.

[Serusers] load testing mediaproxy for more than 50 calls
by Simone Cittadini 31 Aug '05

31 Aug '05

I need to test the new ser/radius/mediaproxy server we have bought. As a fast upper bound to the maximum number of concurrent calls I tought to use rtpgenerator, but it can't increase the number of simultaneous calls more than 50 ... Is there any way to increase that limit ? (why it is set anyway ?) Launching a second instance raises cpu usage from 0,5 to 98, so it doesn't seems a good solution ...

Does anybody have any tips on solving the following I want to differenciate between offline users and unknown users. When you use lookup("location") there is no differenciation between the two. Does this require uri_db ? Using 0.8.14 Br /Kevin
