Hello everybody, currently the openser.org web site is hosted by Voice-System server. It has to be moved on a separate hosting server, so that developers and contributors can have full access to it. Are you aware of a good hosting service? It has to be a Linux/Unix server, allow ssh access, provide a good bandwidth and the price to be as much as possible. I have opened a topic in openser forum, too, -- you can use what you like more to reply. Daniel

[Serusers] Portal for forking call to preferred end device - sequential ringing

by Aisling

Hello all, I'm hoping someone will offer an opinion as to how I should approach the following and if I am thinking along the correct lines: I am creating a web application where a user can dictate which device they want a call delivered to. So if I have a user with sip url "sip:2000@server" and they have registered with the SER server from a pda, pc and laptop, SER will currently parallel fork a call to all these destinations causing all softphones to ring (correct?). However I want a user to choose from a drop down menu in their browser (which I'm developing with servlets and JSP's) their preferred phone e.g. pda and then SER will fork the call to the softphone on the pda first. So basically my current plan is to retrieve the information from the user about their preferred phone (which will be associated with a particular IP address) and then dynamically modify the ser.cfg for a sequential forking rule for that user. I would appreciate opinions as to whether I am approaching this correctly or if there's an alternative method for such functionality (perhaps such as forking the call to the device which last registered or something)?

Undocummented code = non existing code (for almomst everyone except the developer and few guys reading the devel list, updating the working copy of the CVS, and checking the new code).....I know it is unpleasant, but two lines with an overview is not asking too much.....isn't it? my contribution, Samuel.

Are you suggesting that commits should be rejected if they do not update documentation as well ? What is better, having undocumented code or having no code ?

Re: [Serusers] Is there an AVP to alter "expires=" in REGISTERmessages?

by Samuel Osorio Calvo

I was taking a more detailled look at the code and it seems that the Contact header will not be added into the reply if you use save_noreply+sl_send_reply because the Contact buffer is added inside the registrar module....but I recall that it worked. I suggest you to give it a try and see the answer with ethereal|ngrep|* maybe it is taken after when constructing the answer from the sipmsg. Anyhow it would be easy to add a save_extended_expires command that makes what you need but, as I said, people can start using these SIP patches to build even more non-compliant proxies with SER....

[Serusers] openser/ser - avoiding forks

by Andrei Pelinescu-Onciul

I think that a fork is bad for everybody. Whatever way you put it, it will still involve extra overhead at least for each code merge. So this mail is an attempt to come to a compromise that would be acceptable for everybody. My first proposal would be to have another branch on ser cvs (berlios). Something like openser_0.x.y (where the version number should reflect somehow that it's newer than 0.9 but not unstable). Bogdan and Daniel would mantain this branch and they would be able to release from it as often as they want. It would be some kind of stable on steroids :-) This would have the main advantage that code merges/diffs/fixes propagation would be much easier and much faster. Administrating all the stuff will be also easier (like common bug tracking system a.s.o). It would be also easier for users, it will be much more easier to keep track of the changes and to choose an appropiate version. There must be however some rules. Something like: backporting/forwadporting from unstable/stable should be ok, the same for minor patches (e.g. xlog colors), but not major code changes, not present in unstable and without the code maintainer approval (to maintain future compatibility). Adding new stuff (new modules) should also be ok, but it would be preferable that these module come from either unstable or experimental. The mailing list for development should remain serdev. For users it could be a different one (if the changes or the mail traffic gets too big). As far as integrating new contributions faster in unstable, I agree that this is a problem, but I think we can sort it out. The experimental repository is a beginning and if there are better ideeas on how to speed things up while maintaing sanity, please speak. Maybe some kind of reviewed patches (e.g: someone sends a patch that adds a new feature in core, Bogdan reviews it decides it's ok and blesses it => I will integrate much faster something blessed by other ser developer). If you don't agree with my proposal, please say what you don't like and what you would like changed so that it would be acceptable for you. I'm sure that we can reach a compromise and hopefully improve ser development pace in the process. Andrei

[Serusers] avp_pushto() + append_branch() not working

by Java Rockx

Hi All. I just need a sanity check regarding avp_pushto() for serial forking. Someone please correct me if I'm wrong here. When processing an INVITE message which results in a 486 Busy status my failure_route[] gets invoked. In the failure route I use avp_pushto() to load the next leg of the call in to the $ruri and then call append_branch() and lookup(location) prior to t_relay()ing the message. Using ngrep I do see the R-URI being changed to the value used in the avp_pushto() call, but the IP address that the INVITE is then sent to is the same as the IP address of the SIP router, which I cannot understand because I do call lookup("location") before t_relay() In otherwords, if my sip router, sip.mycompany.com<http://sip.mycompany.com>has an IP of 71.72.73.74 <http://71.72.73.74> and I use avp_pushto() to set the R-URI to 1001_at_sip.mycompany.com, lookup(location) does return TRUE, but ngrep still shows the INVITE leaving the SIP router and going to 71.72.73.74<http://71.72.73.74>(ie, itself) rather than the IP address in usrloc. Is there anything obvious that I'm not doing that would cause lookup(location) to return TRUE, but not change the R-URI accordingly? Regards, Paul

[Serusers] voice sniffing

by Iqbal

Hi I have managed to get voice calls sniffed, by using a external sniffer. Does anyone know how I could bind a username/caller/caller tag to each wav file. I am not sure this is possible because the voip stream doesnt really have this info, but since my users are making calls by sending invites etc to ser, could I use ser to get the ID's and then call the sniffer to tag the names....or has anyone come across a really good voip sniffer Iqbal

[Serusers] Is there an AVP to alter "expires=" in REGISTER messages?

by Java Rockx

Hi All. We've got some ATAs that don't quite re-REGISTER in a timely fashion and therefore SER expires the usrloc record a few seconds before the ATA sends another REGISTER message. Is there an AVP or something to add, for example, 60 seconds to the "expires=" value in the REGISTER message prior to calling save()? By doing so, these "broken" ATAs would re-REGISTER before SER removes the usrloc record from cache. Regards, Paul
