XCAP over SIP
by Krishna Kurapati 23 Sep '11

23 Sep '11

Hi, The document http://kb.asipto.com/kamailio:presence:k31-made-simple describes that XCAP can be sent over SIP instead of over HTTP. I tried to do however, the server is unable to update presence rules. I was using PUBLISH method. I was using content-type = text... Has anyone used SIP to send over XCAP? Appreciate if someone could share a link or configuration changes required. Thanks Krish

perl module compilation on centos
by Daniel-Constantin Mierla 22 Sep '11

22 Sep '11

Hello, while building the v3.1.5 RPMs, the perl module failed to compile on centos 5 and 6, with following error: error: `PL_unitcheckav' undeclared (first use in this function ) so its packaging was disabled. It works fine on opensuse and fedora. Someone on twitter tried with the package perl-ExtUtils-Embed (like in fedora) and worked. However, OpenSUSE Build System fails to find that package. Is anyone here with latest centos 5 or 6 that can try compilation of perl module in v3.1.5 and let me know the result? Few months ago, it didn't fail for v3.1.4. Thanks, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Oct 10-13, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

But FreeSwitch don't use MySQL like Asterisk? So adapting isn't that easy or...??? On 21/09/2011, at 16.18, David <david(a)styleflare.com> wrote: You can adapt pretty easily.

Re: [SR-Users] Problem with REGISTER retransmissions
by Daniel-Constantin Mierla 22 Sep '11

22 Sep '11

Hello, I tried to reproduce with a very simple config to handle register requests. So I sent a REGISTER with expires 60 (very much the same as the one in the trace you sent), waited a while, then sent two REGISTERs having the CSeq incremented. All went fine. I tested with master and 3.1 branches (so the last is actually 3.1.5). Can you upgrade to 3.1.5 first and try again? If still fails, then update config to print the return code for save() function, something like: $var(r) = save("location"); xlog("code returned by save is $var(r)\n"); if($var(r) < 0) send_reply("500", "Failure"); Let me know the value of the returned code for the register that does not have a contact in reply.

Re: [SR-Users] Dialog module showing calls that have already been terminated

Only on INVITE? On *all* in-dialog requests, i.e., all requests which contain a To tag.

However, you seem to call that route only from BYE and CANCEL requests, missing out ACKs, which is likely the reason why things go wrong. So make sure you run all in-dialog requests through that route, and you should be fine (hopefully). Cheers, --Timo

Kamailio Development Training, San Francisco Area, October 2011
by Daniel-Constantin Mierla 21 Sep '11

21 Sep '11

Hello, since I am attending GSoC'11 Mentors Summit and come to Bay Area again, it is time to bring the developer training in USA, therefore I am planning to organize a two-day seminar focused on developing Kamailio extensions in C. Among topics to be approached: - internal architecture - SIP parser - memory manager - locking manager - database API - config file language interpreter - RPC interface - pseudo-variables and transformations framework - module interface – write your own extensions in C as modules - inter-module APIs - tm, presence, a.s.o. - documentation docbook format This kind of training follows the pattern from the past, trying to keep a low attendee fee, targeting just to cover the expenses with the organization. I am discussing with several people for a good location at a convenient price, however, I am open for new alternatives, including companies/institutes that want to host the event at no cost in exchange of sending few attendees free of charge. Contact me if you can help here. Training is planned for October 24-25, right now the estimated fee per participant is 350USD (it will not exceed 400USD). The policy to accept people is first come, first served. You can register at this time to reserve your seat(s), emailing to me or to registration(a)kamailio.org. Number of seats is usually 10 to 20, last one organized in February in Barcelona filled up quickly. Once there will be enough interested people and a location selected, I will have more precise details regarding the participation to this seminar and I will send updates. Looking forward to meeting many of you and get new US developers on board of the project in the near future. Cheers, Daniel -- http://www.kamailio.org/w/daniel-constantin-mierla/
