Hi, there are two ways to get the mysql module compile: 1) edit the Makefile and remove mysql from the "exclude_modules" list. Later just do "make all" and "make install" 1) do (for compile and install: make include_modules=mysql all make include_modules=mysql install regards, bogdan Ferianto siregar wrote: > Dear Bogdan, > > Thank you very much for your response.

[Users] plz help me

Hi users; i am new to use openser.I have to implement example like (http://www.voice-system.ro/docs/avpops/ar01s08.html#ex_trusting).in this (# do proxy authentication)parts create problem for me .plz help me to find which is the proxy authetication part in openser.cfg1(which is orignal file having no modification). i am also giving openser.cfg2 (modified file by me) plz find out the mistake i am doing .plz solve my problem .i think there is some problem in configuration because after some modifation in configuration file when i am going to start my openser it gives me message like:OPENSER STARTS FAILED PID does not exist .

[Users] Flags In Openser-1.01

by Michael Papet

-- Hi: This is a newbie question: I have some logic where I setflag(3) after successful login authentication and before route(X). If I use isflagset(3)in my route(X)to verify the account has passed authentication it returns false. I am assuming that means that flags aren't persistent and I need to use some other mechanism to set a variable in one part of the openser.cfg program to use in another. What is my best option?

[Users] ";user=phone"

by Mark Kent

An upstream PSTN-gateway provider wants SIP Request-URIs in this format: INVITE sip:16509411212@x.y.z.w;user=phone SIP/2.0 To achieve this, I did: rewritehostport("x.y.z.w;user=phone"); t_relay(); which works, but makes me uneasy as the stuff after the ";" isn't really the host or the port. What is the official way to put "user=phone" on the end? Thanks, -mark

[Users] Please help for Building TLS in openser1.1.0-tls_src.tar.gz

by Ferianto siregar

Dear all, First, My special thanks to Bogdan who has helped me to solve my problem in building my openser system and Thank you very much to all the users in this forum. Thanks. I use openser.1.1.0-tls_src.tar.gz. I have built it as shown in the installation guide from openser website. In my openser system, I plan to build TLS, so I build it by using command: # make TLS=1 all # make TLS=1 install The installation progress run without any error. But, I have some questions about the installation. They are: 1. How can I check the TLS in my system? I mean How I check whether it has built correctly or not. 2. Can I test it before I configure the openser.cfg file? or I must configure it first? 3. About the certificate, If I use the default certificate (which comes in the packet), how can I configure the certificate for tls_certificate, tls_private_key, and tls_ca_list. Do I need any configuration or I just enable it by deleting the "#" character)? Because as I shown from any massages in this forum, everybody who sent their openser.cfg file, use their own certificate. But,in this case, I don`t have any certificates because I don`t know how to get it (should I buy it or not) I do hope anybody can help me. So, my problem in understanding TLS system can be decreased. Please help me...Please Thanks with cheers Ferianto --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls. Great rates starting at 1¢/min.

[Users] New feature: fetch support in database API

by Daniel-Constantin Mierla

Hello, the CVS head has now support for fetch-result capability in MySQL driver. The usrloc module is already using it. The new feature allow to do incremental load of location records from database. This removes the issue of 'out of private memory' when dealing with huge numbers of active subscribers, with no hacking into the code. Just as an example, with default OpenSER parameters and compile flags, you can load up to 120 000 location records (within 32MB of share memory and 1MB of private memory per process) - the whole used system memory being about 40MB with default config file. For same number of location entries, but without this feature, OpenSER/SER requires about 256MB. At this moment, the private memory becomes irrelevant, user location scaling being linear with size of share memory you want to allocate (share memory size can be given via command line parameter -m) -- 256MB of share memory should enough for 960 000 location records and the private memory per worker process can still be 1MB. More details: http://www.openser.org/index.php?option=com_content&task=view&id=48&Itemid=9 Next step on this scalability direction is to have asynchronous user location loading - usrloc database records caching will be done by one of the openser children, the others will process SIP messages - this results in faster openser start/restart. Cheers, Daniel

[Users] parsing P-Asserted-Identity

by Klaus Darilion

Hi! I wonder how I can parse the body of the P-Asserted-Identity: header. This header allows several syntax, e.g: P-Asserted-Identity: "Klaus Darilion" <tel:+43123> P-Asserted-Identity: tel:+43123;context P-Asserted-Identity: tel:201-555-0123;phone-context=+1 P-Asserted-Identity: "nice guy" <sip:ng;abc=def@nicedomain;foo=bar> In my case I want to: 1. check if it is a tel URI or not 2. Get the phone number from the addr-spec 3. Get the parameters (phone-context, ...) Are there generic functions available to parse name-addr, addr-spec, SIP-URIs and tel URIs? Or do I have to use avp_check and avp_subst with some complicated regexps? Thanks Klaus
