[Users] Last Hop Detection
by Tavis P 28 Jun '06

28 Jun '06

I'm trying to find a way to detect if a BYE message that is being routed between two proxies is at the last hop before being sent to the endpoint. I tried checking for a existence of the "Route" header field, but i gather its removed on the way out so is present until its routed I also tried comparing the value of the "Max-Forwards" header field to an arbitrary integer but i was unable to find a way to do that either The purpose is to avoid double accounting messages that traverse two proxies in our network, is anyone aware of a solution to this problem? tavis

Hi Ferianto, that's a quite know problem with some openssl packages - you need to disable the kerberos support into it, otherwise it will not compile properly. regards, bogdan Ferianto siregar wrote: > Dear all, > > I try to compile the TLS Support in my openser.

[Users] Problem with forking
by Kenny Chua 28 Jun '06

28 Jun '06

Hi all, I was wondering what is the max children I can spawn. When I set children = 32 I got this error when doin openserctl moni: Error opening openser's FIFO /tmp/openser_fifo Make sure you have line fifo=/tmp/openser_fifo in your config Seems like openser or my system can't support that many children? I read that in the core cookbook that max children was 32. Wonder why it crashed on my system. Its a Dell Server, specs should be Pentium 4 3 Ghz with 1 GB ram. I think this spec should be enough to support 32 children. Here is the debug error. 51(4998) ERROR:domain_db_init: cannot initialize database connection 51(4998) 52(5000) new_connection: Too many connections 52(5000) ERROR: child_init(50): Error while connecting database 52(5000) ERROR:init_mod_child: Error while initializing module usrloc, rank 50 52(5000) init_children failed ERROR: domain:child_init(): Unable to connect to the database What am I suppose to do to fix it? I'm using mysql database. Is it because mysql needs to support more connection? How am I suppose to change that? Thank you --------------------------------- Talk is cheap. Use Yahoo!

Dear all, I try to compile the TLS Support in my openser. I use openser-1.0.1-tls and The operating system is Redhat. I have done some commands like: 1. localhost@root # export TLS=1 2. Uncomment (enable) TLS =1 in Makefile 3. localhost@root # TLS=1 make all I do those task based on the tutorial that i have read from www.openser.org/docs/tls.html. But, when i run the make command, TLS=1 make all, there is an error message. The error message is make: *** [main.o] Error 1 Does someone can help me to solve this problem? What should i do ?

Dear all, do anyone know how to t_replicate to multiple proxy, I tried putting two t_replicate statement back to back but it only replicate to the first proxy, not the second. t_replicate("sip:xxx.xxx.xxx.xxx:5060"); t_replicate("sip.yyy.yyy.yyy.yyy:5060"); thanks Ray

[Users] more on accounting
by tele 28 Jun '06

28 Jun '06

Hi all, I'm using OpenSER v1.0.1 and i have done an accounting compatible with my billing system. Now i have problem with detection of flow direction for billing reason. i'm talking about openser 1.0.x: the problem is when the BYE come from callee. i know the problem is solved in openser1.1.x with the modparam("acc", "detect_direction", 1) i have read in modules documentation of 1.0.x that i can use is_direction() of RR module for detect call flow direction but it says that this must be called after loose_route() so for the accounting i must call setflag before loose_route() but what can i do if i want detect call flow before of exec setflag? Hmmm i think that i must install OpenSER 1.1.x and test with it :tele

[Users] Multiple Sockets + Multiple Processors: Any known issues?
by Carsten Bock 28 Jun '06

28 Jun '06

Hi Everybody, I have some problems with a System which has several network interfaces and multiple network interfaces. The system basically receives requests on the public socket/ip and sends them, via the private socket to some proxies, which "do the work". It's a kind of load-balancer based on OpenSER 1.0.1 and the Dispatcher Module from 1.1 / CVS. Everything works fine, but sometimes i see some ICMP Messages (Destination not reachable / Port not reachable) on this "loadbalancer"; as a response to requests from the Proxies to the loadbalancer. Has anybody seen this issue before? Any ideas, what's wrong? Any known issues? Are there any known problems with multiple interfaces? Any known issues with more than one processor? I've copied my configuration below, any thing in capital letters are Parameters from my M4 file... The system is not really on high load, has 64 children and should easily handle the load... (Dual Intel Xeon(a)2.80GHz, 1 Gig of Ram) Any help would be appreciated...

[Users] Is there a way to leave a route block and return to it where you left?
by Brandon Price 28 Jun '06

28 Jun '06

I have a route block that performs callerid name lookups for incoming calls. I want to leave this as a separate route block, and not include it into the incoming route for simplicity of development. I basically want to hop out of route 2 down to route 101, then hop back to route 2 under the line that is pointed to. Any clues,? can this even be done or does the structure of the tm (being stateless) limit it? Is there a way to hop to a certain line number of a route like say route(2,4); going to route 2 line 4. I dunno. ############################################################### # INCOMING ############################################################### route[2] { xlog("INVITE Received (incoming): $fu -> $ru"); setflag(1); strip(1); route(101); <--- do more stuff ......................................... ######################################################################## ################################## # CNAM ######################################################################## ################################# route[101] { xlog("Running cnam query"); # do some stuff.... return; };
