[Users] using AVPs to write into database

by Jayesh Nambiar

Hi all, I am trying to implement the call forwarding feature in openser. The forwarding part is fine. But I have the follwing scenario: Whenever a user needs to change his forwarding number, he should be able to do so from his end device only. For eg: He first presses 86 and then the 10 digit number to be forwarded. Here the 86 has to be stripped and the 10 digit number should be inserted into the call forward value column of the preferences table. Also if he wants to remove the forwarded number, he can do so by pressing say for eg: 87. on receiving this number openser should delete that value from the table. Is this possible. I tried to do the following, but somehow it does not change the value. if(uri=~"^sip:86[0-9]*@") { if(avp_db_load("$from/username", "s:callfwd")) { #check if call-fwd feature is enabled for the user log(1,"AVP condition returned true"); strip(2); avp_write("$ruri", "s:callfwd"); avp_print(); log(1,"AVP written"); sl_send_reply("200", "OK"); exit; }; }; Is avp_write the proper method or I guess avp_db_store can also help me. The avp_print() function also does not show me anything in the log. Are there any logical mistakes or I have mis-interpreted the syntax of avpops functions. Please help me in thsi regard. Thanks a lot in advance. Jayesh. --------------------------------- Jiyo cricket on Yahoo! India cricket Yahoo! Messenger Mobile Stay in touch with your buddies all the time.

[Users] How to test for domain in sip request in openser.cfg.

by Bas Driessen

Hello, I would like to test for the domain name in a sip request to decide if an invite is accepted or not. I have the following lines in my openser.cfg file to cater for DNS SRV forwarding: # accept calls from foo.com if ( is_method("INVITE") ) { rewritehost ("sipproxy.foo2.com"); rewriteport (""); } This works well, but I would like to tighten security by only allowing invites forwarded by foo.com. When debugging using xlog calls, the pseudo-variable I am after is : $rd. However $rd can not be used in openser.cfg as follows: if ( is_method("INVITE") && $rd="foo.com" ) Documentation suggests to use core keywords like: if(is_method("INVITE") && from_uri=~".*(a)foo.com") This does not work for my situation and I don't know how I can see the value of 'from_uri', as it can't be expanded into xlog calls. So my kind of overlapping questions are: How can I use pseudo-variables in openser.cfg to test for a certain value? How can I see (debug) the contents of a core keyword? Which keyword should I be using to solve this issue? Has anyone solved a similar issue in the past and if so can you please give some details? Thanks, Bas.

[Serusers] how can I set up the SER and Asterisk in two Linux servers?

by Josh Zhou

Hi, I am new to the VoIP. My plan is to have SER in one Linux server, and have Asterisk in the other Linux server. Can you share your experience with me what I should do with the configuration file in the SER and Asterisk? So that SER and Asterisk can interwork together. Thanks a lot. Josh

[Users] Re: Persistent Data Storage

by Klaus Darilion

Hi! Please send your emails to the list. This way others can help you too, and others will also benefit. In Openser, all DB task will be done via openser's DB layer. Thus, the modules do not have to take care of the used DB. Under the DB layer, there are the DB drivers: There is at the moment mysql, postgresql and unixodbc. When configuring openser, you only have to use the proper configuration, thus use "postgres://..." isntead of "mysql://...." For setting up the database, use the openser_postgresql.sh script. For setting up openser in general, please refer to the Gettign Started Tutorial on onsip.org regards klaus voiceoverip wrote: > Hi Klaus, > > forgive me for being a nuisance:) I've tried google and Openser manuals, > haven't been able to find any revelant Openser setup guide with > PostgreSQL, would be glad if you can point me to any online reference(s). > > Also, I assume that by native, you meant the client interface to the > underlying DB platform.
