[Serusers] RE: Back to Back INVITE?
by xwang＠cascotec.com 23 Sep '06

23 Sep '06

Hello I have SER and RTPPROXY installed. Everything works fine till we debug a softphone. I use SPA3000 to dial, the receiver is a softphone. The softphone registers correctly. When dialing from SPA, here is the handshaking sequence SPA3000 -- INVITE --><-- TRYING SER -- INVITE -- INVITE --><--TRYING RING softphone. There is a back-to-back INVITE sent out immediately by SER to the softphone. I don't see those sequence to call other UAs. Does anyone know why SER sends two INVITE? Thanks! Steven

[Users] ACC module - important changes
by Bogdan-Andrei Iancu 22 Sep '06

22 Sep '06

Hi everybody, I just commited on the CVS a grand ACC restructuring and clean-up. Here is form commit log: - simplify internal logic for preparing and message selection - more efficient data collection - eliminate the FMT-based accounting; instead of it, a default set of basic values are all the time accounted; for more, extra accounting should be used -> this leads to a more selective / flexible / performant accounting - pre-builds sets of names / columns / RADIUS AVPs / DIAMETER AVPs instead of doing it each time a request is accounted - "n/a" string for not found/available values replaced with empty string "" - eliminated a lot of un-necessary functions - heritage from the all TM callback design (pre pre-transaction transaction) - DB accounting table redesigned - accounting logic separated in a new file for a better modularity. - implemented an accounting environment for storing data; helps in reducing the number of function's parameters and of internal functions; more important, useless conversions from str to int and to int again are eliminated The most important change was the drop of FMTs for a more flexible system: have a basic set of values used of call matching, plus the usage of extra accounting for anything more. The basic set is defined to : method name From URI From TAG To URI To TAG CallID Cseqno Reply code Reply reason Time stamp having a timestamp generated by the proxy instead by the backend (syslog, RADIUS server, SQL server) is important as it is more accurate - the delays due transport to the backend server are eliminated. Also the time is logged in UNIX timestamp format to avoid confusions about timezones. From how to use it (enabling acc via flags), nothing changed :)..only some module parameters were lost. For more details, please see: http://openser.org/docs/modules/1.2.x/acc.html any feedback is welcomed regards, bogdan

Re: [Users] Checking for Digit Length

Dialling rules aside, is > there a way? Unless I missed it, no one told the guy what he needs to know. Instead, he is pointed at a lengthy specification for posix regular expressions. I know there is value in teaching a guy to fish, but at some point someone has to just answer the question... This if (uri=~"sip:[0-9]{10,24}") { ... } will match a sequence of digits between 10 and 24 in length (inclusive). Now, the above is not a great test in practice. I don't know how long the longest number can be outside the North American Numbering plan (where it is relatively easy: 1-NXX-NXX-XXXX, see nanpa.com). And there are restrictions on the first few digits that you might want to check, depending on where you are in the world. I'm sure that someone reading this list has already got the ultimate, global, number checker coded for openser... it's just a question of whether they'll cough it up in public. -mark

Is it possible in someway to extract the actual number of active sessions in RTP Proxy. There is sessions_created variable but its a cumulative count of sessions created. Gaurav

[Users] compiling OpenSER on Solaris 10 x86
by Nick De Cristofaro 22 Sep '06

22 Sep '06

I'm having a lot of difficulty compiling OpenSER on Solaris 10. Firstly I was missing a lot of packages which I needed to download from sunfreeware.com (gcc, ld) the /usr/bin/ccs version of make does not work on the makefile here is the error: bash-3.00# make make: Fatal error in reader: Makefile.sources, line 18: Unexpected end of line seen I looked in the file but I don't see how it would complaing of some unexpected end of line. I then followed to try GNU's make I downloaded. and then I get an error on the /usr/bin/ccs/lex and yacc's (it mentioned to use yacc and not bison) the error was: bash-3.00# /usr/local/bin/make all yacc -d -b cfg cfg.y conflicts: 1 shift/reduce lex cfg.lex "cfg.lex":line 102: Error: missing translation value make: *** [lex.yy.c] Error 1 Then I decided to try flex instead of lex. bash-3.00# /usr/local/bin/make all yacc -d -b cfg cfg.y conflicts: 1 shift/reduce flex cfg.lex flex: fatal internal error, exec failed make: *** [lex.yy.c] Broken Pipe make: *** Deleting file `lex.yy.c' so I'm kindda stuck, it's apparently been compiled on the x68 s10 platform before so there must be some sort of makefile modifications I must make everywhere ? Anyone know what may be going on? I was hoping there would be a package OpenSER version for solaris built somewhere :S Thanks! Nick

[Users] rtpproxy bridge mode with multiple handsets per extension
by David Carter 22 Sep '06

22 Sep '06

Good afternoon, I have a small openser test rig with rtpproxy running as a bridge between two networks: rtpproxy -l <public IP>/<private IP> -s /tmp/rtpproxy.sock This works well apart from one issue. I have set up two handsets for an extension, one on the public network and one on the private network. The idea is to provide one phone in the office and one at home, so I can pick up at either location when someone calls. If I call the extension both handsets ring correctly, but audio is only set up correctly for one of the two handsets when I pick up. Everything works fine if both phones are on the public or the private network. I infer that this is because primitives working on the ruri and friends: avp_write("$ruri/domain", "i:20"); only work on the address of the first registered handset that they find, even if lookup("location") has created multiple branches. Does anyone have any ideas or workarounds which would allow me to set up multiple handsets for a given extension when bridge mode is involved? I tried abusing the aliases table to redirect an incoming call onto multiple SIP URIs. It looks like rtpproxy indexes by Call-ID, and hence struggles with multiple branches which share a single Call-ID.

Just put your IP instead of the name. Then this SIP_DOMAIN will be used to properly add contacts to your subscriber table.

Try also to specify alias as you IP address, i.e. listen="202.x.x.x" alias="202.x.x.x" You may also try to add a domain entry to the domain table with serctl (that is if you use functions in your config such as "is_uri_host_local()"), i.e. serctl domain add 202.x.x.x Hope it will work for you.

RE: [Serusers] SIPP with SER
by Verbeiren, David 22 Sep '06

22 Sep '06

> Hello , > > has anyone any experience on testing SER with SIPP ?? > > I've sent the following mail to sipp-users mailing list, I'm sending it > also here, in case anyone has any idea or experience. This may not be exactly what you want to test but I've done tests with SIPp and various SIP proxies, SER being one of them, by targeting the UAS itself on the SIPp command line but with a "remote sending address" parameter specifying the proxy to use. This works great and does not require the 'service' user to be known to SER as it simply looks at the hostname (or ip address) part of the URI to proxy the call. This gives the following modified command lines: UAC : ./sipp -sn uac 2.2.2.2 -r 1 -m 1 -d 5000 -i 1.1.1.1 -rsa 3.3.3.3 UAS : ./sipp -sn uas -rsa 3.3.3.3 The remote sending address is similar to the "outbound proxy" parameter found on many SIP phones. This way of running SIPp gives the call flow you describe but shortcuts most of the ser.cfg routing logic as uri!=myself. Regards, -David
