[Users] new features: script variables and pseudo-variables in script
by Daniel-Constantin Mierla 29 Jan '07

29 Jan '07

Hello everybody, the development version allows now ability to use pseudo-variables directly in configuration file. In addition to old pseudo-variables you know, a new type was introduced: script variables - the format is $var(name) where name can be any string of digits and characters. Basically this are variables that can have integer or string values and they can be set directly in the configuration file via 'assign operation. The big advantage is that they are directly referenced at runtime, avoiding searching each access time. They are specific per processes and survive over multiple sip message processing (be sure you set the value before testing it -- e.g., $var(counter) = $var(counter) + 1 at the beginning of main route is a counter of messages processed). The script variables are initialized at startup to '0'. You can shift between value types: e.g., '$var(a)=1; $var(a)="openser";' is valid. The switch statement can be used now with any valid pseudo-variable ('retcode' must be now replaced with '$retcode' to get old behavior). switch($rU) will compare the r-uri username with 'case' values. The case 'values' can be string or integer. switch($rU) { case "101": xlog("dialed number is 101\n"); break; case "102": xlog("dialed number is 102\n"); break; default: xlog("dialed number is $rU\n"); } Assignments of script variables, AVPs, R-URI parts (username, domain, and URI) and dst URI can be done as well in script. $avp(i:11) = 1; - sets the value of $avp(i:11) to integer '1' $avp(i:11) = "1"; - sets the value of $avp(i:11) to string '1' $ru = "sip:"+$var(user)+"@"+$fd; - sets the R-URI to string composed from value of variable $var(user) and From URI domain '+' can be used to concatenate strings or do arithmetic addition. Other arithmetic operators: - '-' - minus - '/' - divide - '*' - multiply - '%' - modulo - '|' - bitwise OR - '&' - bitwise AND - '^' - bitwise XOR - '~' - bitwise NOT To make sure that the priority of the operators is right, do use parenthesis, it is the best to get expected result: $var(a) = 2 + (7&(~4)); If you want to evaluate arithmetic operations and test the value in conditions, use the test operator ' [ ... ] ' . This is required to convert the result to internal convention for drop, true and false. if ( [ $var(a)&4 ] ) { xlog("bit 3 is set in var a"); } Old '*' used to match any port or proto was changed to 'any' to avoid the conflict with multiply operator. Some operations overlap with several avpops functions. Until sure that all cases are covered in script variant, both will go further, avpops version being scheduled for deprecation. It was a big lump of changes, help in testing and feedback is very much appreciated. Cheers, Daniel

Hi. When I use the function proxy_challenge(), the 407 don't have the parameter 'algorithm=MD5'. Look below: ... Proxy-Authenticate: Digest realm="proxy.com.br", nonce="45be00f941f137ff037436c77f80a9531a02155f". ... How can I put this parameter in digest informations? ... Proxy-Authenticate: Digest realm="proxy.com.br", nonce="45be00f941f137ff037436c77f80a9531a02155f", algorithm="MD5". ... Thanks in advance.

[Users] want to try out openSER
by Ahsen 29 Jan '07

29 Jan '07

Hello ! I have an problem with the SER ..therefore I want to install the OpenSER, but before I install it I want to know whether it can solve my problem or not. I got an shell script which starts a java application , there are no problem with it. But when I start the script with SERs exec module (exec_msg() ) the java application does not support german charset and replaces german spellings with "?". The problem do not occur when I start the shell script manually. I have testet a lot of thinks but the problem still exists. So can someone tell whether he/she has such a problem with OpenSER or not or have an idea how I can solve the problem with SER ? If not I would try out OpenSER ! thanks Ahsen

Hi all, two doubts about OpenSER version 1.2: 1. This version will support MSRP sessions ? It will implements a MSRP Relay? 2. It will support chunking messages ? Thank you very much and Best regards, Danilo Vilela Researcher Inovax Engenharia de Sistemas Rio de Janeiro, Brazil

[Serusers] ser and radius - WARNING! No "known good" password found for the user.
by tzieleniewski 25 Jan '07

25 Jan '07

Hi! I am trying to use freeradius as an authentication server for ser. I use the latest cvs version. I am o newbee with free radius so a kindly ask for your help becouse someone who has manage to done radius support probably wouldn/t have any probelms to point me what I do wrong. I configured ser so it sends the requests messages to radius but I encountered a strange error. Both are running on the same machine so it is enough to use the 127.0.0.1 client configuration from client.conf. I defined realm that would service the request comming with the "voip.touk.pl" domain part in the proxy.conf: realm voip.touk.pl { type = radius authhost = LOCAL accthost = LOCAL nostrip } I also included the digest modules in the authentication and authorization sections in the radiusd.conf. At the end I added the user data in the users file: hellboy Auth-Type := Digest, User-Password := "hellboy", Huntgroup-Name == "voip.touk.pl" Fall-Through = No, User-Name = `%{User-Name}`, Reply-Message = "Accepted: %{User-Name}" And know when SER sends the authentication request radius rejects it and there is this "strange" info" in radius debug rlm_pap: WARNING! No "known good" password found for the user. Authentication may fail because of this. Another thing wich is strange is: modcall[authorize]: module "suffix" returns noop for request 0 When my suffix is defined in the radiusd.conf as: realm suffix { format = suffix delimiter = "@" } here is the whole free radius degub outout: rad_recv: Access-Request packet from host 127.0.0.1 port 32794, id=225, length=299 User-Name = "hellboy(a)voip.touk.pl" Digest-Attributes = 0x0a0968656c6c626f79 Digest-Attributes = 0x010e766f69702e746f756b2e706c Digest-Attributes = 0x022a34356238633234313732386462316132343230333639303633313264366333626338363135306563 Digest-Attributes = 0x04177369703a7465737440766f69702e746f756b2e706c Digest-Attributes = 0x0308494e56495445 Digest-Attributes = 0x050661757468 Digest-Attributes = 0x090a3030303030303031 Digest-Attributes = 0x08223133304432333745384238443837353945304441383438444443323133353542 Digest-Response = "bd2e0fd81858b8114d326394b7b92001" Service-Type = 0x0000000f00000000 SER-Service-Type = 0x0000000300000000 SER-Uri-User = "hellboy" NAS-Port = 0x000013c400000000 NAS-IP-Address = 0x7f00000100000000 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 rlm_digest: Adding Auth-Type = DIGEST modcall[authorize]: module "digest" returns ok for request 0 rlm_realm: Looking up realm "voip.touk.pl" for User-Name = "hellboy(a)voip.touk.pl" rlm_realm: Found realm "voip.touk.pl" rlm_realm: Proxying request from user hellboy to realm voip.touk.pl rlm_realm: Adding Realm = "voip.touk.pl" rlm_realm: Authentication realm is LOCAL. modcall[authorize]: module "suffix" returns noop for request 0 modcall[authorize]: module "files" returns noop for request 0 modcall[authorize]: module "expiration" returns noop for request 0 modcall[authorize]: module "logintime" returns noop for request 0 rlm_pap: WARNING!

[Serusers] Ser - Asterisk small problem
by karim basraoui 25 Jan '07

Hi, I am using an architecture with Ser and Asterisk. When Ser forwards the calls to asterisk, everything is all right. the caller has a "ringing" message and the callee rings. when the callee picks up, the caller has a "connecting" message but the callee hungs up suddenly. my asterisk shows the message: -- Got SIP Response 503 "server error" back from Ser_ip -- how can i tell to asterisk to setup the call ? thank you ! -- BASRAOUI Karim

[Serusers] SER forwarding to Asterisk
by karim basraoui 25 Jan '07

25 Jan '07

Hi, The topic may have been already discussed, but still there are some problems. I have an architecture like this : UA1 ->SER -> ASTERISK -> UA2 when UA1 sends an INVITE to UA2, SER forwards the call to ASTERISK, i can hear UA2 ringing. however, when UA2 answers, i can see "connected" on UA1 but UA2 hungs up by itself, as if ASTERISK cancels the call. is there any solution to oblige ASTERISK to forward the "200 OK" to SER? thanks in advance -- BASRAOUI Karim
