[Serusers] Carrier-grade framework for SER

by Andreas Granig

Hi guys, I'd like to propose another possibility for a highly-available and scalable system design based on SER: The problems I've encountered for scalable systems are: - Distribution of the user location and alias location among the nodes (user location is based on registrations, alias location comes from web interfaces and is used for call forwarding). - Reloading up to date location tables after breakdown and recovery of a node So I'm just thinking loud about the following provisioning system: - Write a client which fulfills the this demands: - Receive one or more locations from SER via a SER module or from a web application and distribute them to other known clients. Take care of retransmissions if a client isn't reachable or reports a temporary failure. - Receive one or more locations from other clients and write them into the SER FIFO. If writing into the FIFO fails, try to write directly into the database (location-table, alias-table etc.). Report a temporary failure if this also fails. Maybe a centralized server should be used which receives the locations from the clients and distributes them to other clients, so that the nodes just know about the server and nothing about other nodes. This would make integration of new nodes easy. On the other hand, it's another single point of failure, so a decentralized solution should be considered. But that would mean that you've to inform every node about the existence of a new node. The protocol used between the nodes should be simple and fast. So I think SOAP drops out here. Maybe XMLRPC or ICE (http://www.zeroc.com/ice.html) could be used. One might think now why not just use replication on SIP layer, but t_replicate only supports one peer and you've no possibility to get locations on a node while it's down. Replication of other location tables like the alias-table is also not possible. I'd be willing to release these parts as GPL for creating an open framework for carrier-grade SER integration, so any feedback, improvements or flames are highly welcome. Cheers, Andy

Hi Gang. The company I work for is interested in buying DIDs from Europe. Of course the connection should be SIP. If any of you is selling them, please contact me off the list. Regards Juan Ferrari VoIP & Telecom Specialist United World Telecom Phone: +1561-276 7156 ext. 302

[Serusers] Routing users to other SIP server

by KaveH Aasaraai

Hi, I was wondering how I can route my SER users to other SIP servers, without need of authentication to other server. I mean this: My User -> Auth -> My SER My SER -> Auth -> Other SIP Server My User --------make call--------> My SER --------route call-------> Other SIP Server Thank you.

RE: [Serusers] RTP proxy between two subnetworks with private @s

by Jose Soler

Hi Joao, No I was not able to solve the issue. It seems (this is my guess tough) that the Portaone RTP proxy assumes that it has one public IP adress, so the valid configuration to use it is Public Nt-Private Nt. I was not able to make it work in other configurations (neiher I got feedback from Portaone to do so). Nevertheless the code is available, so it could be modified...as long as you have the time and will to do so. I did not ;). Best regards, josé -----Original Message----- From: Joao Pereira [mailto:joao.pereira@fccn.pt] Sent: 19. oktober 2005 20:17 To: Jose Soler; serusers(a)lists.iptel.org Subject: Re: [Serusers] RTP proxy between two subnetworks with private @s Hello, did you made it to put the clients of networks A and B to call each other? I want to do the same, and tried a lot of SER/RTPproxy configurations, including the one in: /ser-0.9.0/modules/nathelper/examples/alg.cfg and also tried to run rtpproxy with the "-l 10.0.0.135/193.136.2.2" option. But I just was able to ring the phones (wen calling between networks), but the RTP doesnt pass... If you found the solution, please tell me.

[Serusers] Modifying "From" header field of an INVITE message

by scm-j＠nuntius.com

I am relatively new to SER. My SIP service provider requires me to present the ANI in the "From" field in my INVITE message header in E.164 format. I am currently sending this information as follows: From: "2125551212" <sip:2125551212@xxx.xxx.xxx.xxx> They want it in E.164 format as follows: From: "+12125551212" <sip:+12125551212@xxx.xxx.xxx.xxx> I see function only to modify the SIP URI but not the other header or SDP fields. Could someone help me with a code snippet that I can use in ser.cfg to do this conversion? Regards, SCM

[Users] cancel processing

by Jose Antonio Garvayo

*Hi, I am experiencing a problem regarding CANCEL processing, I have the normal config file plus the following (I got that in a previous mail) * if (is_method("CANCEL")) { t_relay(); break; } The problem is that openserver is relaying the CANCEL, but putting a completely new branch tag in the Via header, instead of the same branch than in the INVITE that is to be cancel. I have debug dump, that shows that the CANCEL message is matched with the INVITE, but it still put a new branch in the relayed cancel, and also in the 200 OK response. If somebody could help me it would be great 0(5309) DEBUG: callid: '2ef6f3df-5309(a)10.161.14.110' 0(5309) DEBUG:init_mod_child: CHILD , rank=1, module=usrloc 0(5309) DEBUG:init_mod_child: CHILD , rank=1, module=xlog 0(5309) XLOG: init_child [1] pid [5309] 0(5309) SIP Request: 0(5309) method: <INVITE> 0(5309) uri: <sip:user4@home2.jagarvayo.mot.dev> 0(5309) version: <SIP/2.0> 0(5309) parse_headers: flags=2 0(5309) Found param type 232, <branch> = <z9hG4bK4f9932cde5bad6c36f103563aa96f449>;

[Users] timeout problem with media gateway

by Matteo Piazza

HI, In my serial forking configuration I have this problem: if i use the a media gateway ( asterisk ) on the same machine ( but I see also on the another machine) of openser ( on the 5061 port) I have a problem with the timeout of a call. The call continues beyond the timeout and when by the PSTN telephone I reject the call appears the following log message: Warning: sl_send_reply: I won't send a reply for ACK!! Where I have mistake? Any idea? Another thing. I see that I redirect the call directly in the media gateway, (for example a location of a user is a PSTN number) whitout the traslation of IP number, all is ok.
