[OpenSER-Users] Mediaproxy Vs RTP Proxy
by Ali Jawad 31 Jan '08

31 Jan '08

Dear All I know that there are two possible setups one usng mediaproxy and another one using rtpproxy. How do these two proxies differ from each other ? And if I chose NOT to use any of these proxies would I be able to make calls through a PSTN gateway located on the Internet ? Thanks.

[OpenSER-Users] dp and dP pseudo-vars
by Victor Gamov 31 Jan '08

31 Jan '08

Hi gentlemen! I use openser-1.2.2 and I want to access to dp & dP variables but sometimes they are empty. I try to access it before and after t_relay() and result is the same -- variable is empty. When this variables are set? Is it possible that they are not set at all? Thanks! -- CU, Victor Gamov

[OpenSER-Users] Reg. Proxy domains
by Padmaja 31 Jan '08

31 Jan '08

Hi all, Please see the situation below: UA1 ----------------------> Proxy 1(not openser)---------------------- Proxy 2(openser)<----------------------UA2 UA1 is registered to proxy 1 and UA 2 to openser. I wish to make a call from UA 1 to UA 2. Proxy 1 and proxy 2 are in the LAN but do not know of each other. Is there a way we can configure the openser to send/receive the invites to proxy 1? I think the calls will be handled on domain basis, so openser will treat all the UAs registered to it as local and allow them to call each other. But how to make it allow inter domain calls? Please let me know. Thanks, Padmaja

[Serusers] SER/FIFO not accessible
by Steve B. 31 Jan '08

31 Jan '08

I am new to SER. I have installed SER 0.9.6-2 on a fresh Kubuntu server using apt. I have been able to get SER to run using the sample ser.cfg files (only changing module paths from /usr/local/lib... to /usr/lib/...). I am trying to setup the mysql support. In a nutshell, when I run serctl I get an error: # serctl add sbelt(a)ser.mytestsite.com sbelt sbelt(a)mytestsite.com MySql password: (here I enter 42serro11) error: SER/FIFO not accessible: 2 # Am I using the correct password? I am not sure which Mysql Password is being requested here. I have also tried the mysql root password with the same result. I have seen other posts similar that seem to indicate it is permissions on the /tmp directory. I tried adding to ser.cfg fifo_mode=0777. I have verified the current user can write to the /tmp directory. Frankly, I do not know if this /tmp/ser_fifo is all a red herring. Thanks for any help on how I can figure out what I am doing wrong.

[OpenSER-Users] Disconnect A SIP User, how ?
by Ali Jawad 30 Jan '08

30 Jan '08

Dear All I need a way to detect if a user is logged in and disconnect him if possible. A better solution would be to detect if he is in a call and disconnect him. My questions would be 1. How to detect if a user is connected ? 2. How to detect if a user is currently in a call ? 3. How to disconnect a user 4. How to stop the call for a user (If possible) 5. If dialog is needed is my install below sufficient ? I was told in the IRC channel with regard to Q 3 that I can use the dialog module to achieve that through sending bye using dlg_end_dlg mi command. I checked the documentation at http://www.openser.org/docs/modules/1.3.x/dialog.html#AEN578 but I do not have modparam("dialog" // and so on lines in my openser.cfg file I have installed 1.3 with MySQL, Jabber and Presence support using the following First I edited the MakeFile and deleted the modules I want from the exclude_modules entry, it showed up as follows exclude_modules?= cpl-c postgres osp unixodbc \ avp_radius auth_radius group_radius uri_radius xmpp \ pua pua_bla pua_mi \ pua_usrloc pua_xmpp rls mi_xmlrpc perl perlvdb \ ldap carrierroute h350 xcap_client db_berkeley seas NICER=1 make all make prefix=/usr/local install Does that mean that the dialog module is installed? I could not find a loadmodule "dialog" line!! With Regards Ali Jawad System Administrator Splendor Telecom (www.splendor.net) Beirut, Lebanon Phone: +961 1 373725 Fax: + 961 1 375554

Re: [OpenSER-Users] CFG problem with 3rd party tool SOLVED(ish)
by Andy Smith 30 Jan '08

30 Jan '08

Hi, ok, I found and solved one issue. The acc radius_extra entries seem to have a maximum lenght that openser can parse so when I break the configuration into two "lines" like this: modparam("acc", "radius_extra", "User-Name=$Au; \ Calling-Station-Id=$from; \ Called-Station-Id=$to; \ Sip-Translated-Request-URI=$ruri; \ Sip-RPid=$avp(s:rpid); \ Source-IP=$si; \ Source-Port=$sp; \ Canonical-URI=$avp(s:can_uri); \ Divert-Reason=$avp(s:divert_reason); \ X-RTP-Stat=$hdr(X-RTP-Stat)") modparam("acc", "radius_extra", "User-Agent=$hdr(user-agent); \ Event=$hdr(event); \ Contact=$hdr(contact); \ SIP-Proxy-IP=$avp(s:sip_proxy_ip); \ ENUM-TLD=$avp(s:enum_tld)") #Billing-Party=$avp(billing_party); \ It all works, I hope OpenSER isnt ignoring the first entry in the cfg file!!!! :S. But its only working if I remove the entry "Billing-Party=$avp(billing_party)", if I change this to "Billing-Party=$avp(s:billing_party)", then all starts fine. Just hope thats how its meant to be! :P Andy.

Re: [OpenSER-Users] CFG problem with 3rd party tool
by Andy Smith 30 Jan '08

30 Jan '08

If I was guessing (without fully understanding the syntax!) Id say the problem was Billing-Party=$avp(billing_party); should be Billing-Party=$avp(s:billing_party); Although in theory both of the above config entries seem to be valid, though different, openser.cfg entries. According to this: http://www.openser.org/docs/modules/1.2.x/avpops.html :S Also, I tried with the second format (with s:) and that then gives me another error when I start openser: 0(0) INFO:xl_parse_name: using hdr type (27) instead of <user-agent> 0(0) ERROR:acc:parse_acc_extra: parse failed in <User-Name=$Au; Calling-Station-Id=$from; Called-Station-Id=$to; Sip-Translated-Request-URI=$ruri; Sip-RPid=$avp(s:rpid); Source-IP=$si; Source-Port=$sp; Canonical-URI=$avp(s:can_uri); Billing-Party=$avp(s:billing_party); Divert-Reason=$avp(s:divert_reason); X-RTP-Stat=$hdr(X-RTP-Stat); User-Agent=$hdr(user-agent); \ Contact=$hdr(contact); Event=$hdr(event); SIP-Proxy-IP=$avp(s:sip_proxy_ip); ENUM-TLD=$avp(s:enum_tld)> around position 319 0(0) acc:parse_acc_extra: error 0(0) ERROR:acc:mod_init: failed to parse rad_extra param 0(0) init_mod(): Error while initializing module acc ERROR: error while initializing modules

Re: [OpenSER-Users] Does CDRTool require Radius server?
by Andy Smith 30 Jan '08

30 Jan '08

Hi Iñaki, ah yeah, I hadnt noticed this before, and diameter. However have you tested this to see if it writes data in exactly the same format to a DB as Freeradius would? For sure CDRTool has been written to work with freeradius and will therefore need the data in a freeradius format/schema... Andy. ----- Original Message ----- @Andy: > but Radius will do all other updates to DB accounting data. But the point here is that accounting is done by OpenSer ACC module, which can use radius or mysql to fill "radacct" table.
