[Serusers] Carrier-grade framework for SER
by Andreas Granig 27 Sep '06

27 Sep '06

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

[Serusers] Modifying "From" header field of an INVITE message
by scm-j＠nuntius.com 04 May '06

04 May '06

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

[Serusers] Authenticate to Active Directory
by Bob McCormick 05 Dec '05

05 Dec '05

Does anyone know if there is a way to authenticate SER to MS Active Directory? I'd like to use an existing user database instead of having to manage users myself, and most of our users are in Active Directory. Has anyone tried this? What are most SER users using for authentication? Is anyone here tying into any kind of existing organization user database?

[Serusers] Over-long fields can crash SER with PostgreSQL
by Karl A. Krueger 28 Jul '05

28 Jul '05

We are using SER with the PostgreSQL module, so that SER and our Asterisk PSTN gateway and voice mail system can use the same back-end database for user records. (Anyone who's interested in how we did this, let me know -- it's still a little shaky, but it pretty much works.) Recently we have encountered a problem: it seems that if any database error occurs, SER hangs or crashes. We have so far been able to mostly work around these conditions by being Really Careful with the database, but it is a little unsettling. The database schema we're working from is practically identical to the MySQL schema that ships with SER. Notably for this problem the lengths of all CHARACTER VARYING fields are the same. The User-Agent field is CHARACTER VARYING(50), for instance. So ... today boss got a copy of Xten's "eyeBeam" software, set it up to register to our SER ... and SER promptly locked up. I looked in the PostgreSQL database log and found this: Feb 10 13:39:32 mabell postgres[13058]: [267] ERROR: value too long for type character varying(50) Whoops. SER tried to insert eyeBeam's User-Agent data, PostgreSQL returned a data integrity error, and SER went bye-bye. So I did a little ALTER TABLE and adjusted the field to length 128 ... then put this in ser.cfg: # Disallow long user-agent if (search("^User-Agent: .{100,}") ) { log(1, "LOG: User agent too long\n"); sl_send_reply("479", "User agent too long!"); break; }; But this is obviously a kludge ... and doesn't fix the problem of one of the *other* fields being over-long. Anyone have any thoughts on this? Robustness patches for the PostgreSQL module or usrloc? Better ser.cfg workarounds to protect the world from malformed or over-long SIP header fields? Should I just change all the database fields to TEXT instead of CHARACTER VARYING(whatever) ? -- Karl A. Krueger <kkrueger(a)whoi.edu> Network Security -- Linux/Unix Systems Support -- Etc.

[Serusers] SER Reliability
by Ricardo Martinez 04 Apr '05

04 Apr '05

Hello list. I have a question about reliability in SER. Suppose that for certain reason, the process "ser" fails, and therefore the SIP Server is down. Is there a way to keep trace of the "ser" process status?? and if the process is not running start a script to restart the process. I know that maybe the "crond" command could be useful for this purpose. Does someone have any clue about this? Or maybe SER has his own "crond" module or something.? I really need and advice about this issue. Thanks in advance Regards, Ricardo Martinez Ogalde.-

[Serusers] INVITE timers in/out
by Daniel Poulsen 16 Mar '05

16 Mar '05

Hi, I have in my ser.cfg: modparam("tm","fr_inv_timer",40) set as a timer so that INVITEs coming from PSTN callers go to voicemail after 40 seconds. This works great for inbound called, however it seems to be a limitation for outbound calls. If the outbound INVITE doesn't receive an ACK in that time period, the call gets cancelled and drops to fast busy. Is there a way around this? Can I set different timers for inbound and outbound calls? 40 seconds seems to be a good amount time so that most outbound calls get answered by voicemail or actual people, but occastionally users will still get a fast busy. Any advice is greatly appreciated. Dan

[Serusers] call busy forward failed
by Charles Wang 15 Mar '05

Dear ALL: I try to make a call from UA1 to UA2, and UA2 is busy. So the call will forward to another UA3.

Re: [Serusers] error: mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy
by Java Rockx 15 Mar '05

15 Mar '05

Charles, you can read through the README that is included with mediaproxy (the server) and the README that ins included in the ser mediaproxy module. Basically you need to first start the mediaproxy Python server. Once that is running you can start ser. rtpgenerator.py is just a stress testing tool. dnssrv is not required if you're just using one mediaproxy instance. If you ever get to multi-host deployments, then you may want to use dns srv records for load balancing.
