[Users] Why is a second RPID header created when I do two subst()?
by Alan Crosswell 28 Oct '06

28 Oct '06

I have two problems: 1. I am attempting to clean up my Remote-Party-ID header so that my Polycom UAs will display the incoming number as a number rather than as a URI. This requires the domain to match that of the UA's server (e.g. siptest.columbia.edu). And, I want to rewrite incoming calling numbers from my PBX to be in 5-digit format and other US 10-digit numbers into proper E.164 format since my PBX and at least one of my ITSPs doesn't provide them as E.164. So, I do a couple of subst() operations on INVITEs. What's wierd is that one Remote-Party-ID header becomes two when it gets to the UA. The call flow is: INVITE r-uri <sip:10508@128.59.59.96:5060> from <sip:9174147124@128.59.59.242> rpid <sip:9174147124@128.59.59.242> Here's the code for the route block: route[10] { xlog("L_INFO","route[10] $ci: method $rm r-uri <$ru> from <$fu> rpid <$re>\n"); # first just clean out the domain name subst('/^(Remote-Party-ID:.*<sip:.*)@.*>(.*)$/\1(a)siptest.columbia.edu>\2/'); # now strip our numbers down to 5 digits subst('/^(Remote-Party-ID:.*<sip:)(\+)?(1)?21285([134][0-9]{4})@/\1\2/'); # expand 10-digit NANP numbers to E.164 subst('/^(Remote-Party-ID:.*<sip:)([0-9]{10}.*$)/\1+1\2/'); # XXX dip the calling name database XXX # ??? xlog doesn't show the result of rewriting it. # xlog("L_INFO","route[10] RPID is now <$re>\n"); xlog("L_INFO","route[10] $ci: RPID was rewritten.\n"); return; } #end of route[10]

[Serusers] Accounting problems after mysql backup restore
by C. Mewes 28 Oct '06

28 Oct '06

After backup and restoring MySQL the accounting did not worked anymore. I could make calls but the amount does not show up. The problem is that o_uri has the format sip:00 + codigo de tarifa pero en la base de datos se esta guardando sin el 00 solamente sip:+codigo de tarifa ( la razon no la se, no he modificado nada de eso ). After changig in accounting $codigo2 = "sip:".$row2->codigo; if ( strncmp ( $codigo2, $row->o_uri, strlen($codigo2) ) == 0) { $tarifa=$row2->tarifa; $nombre=$row2->nombre It works again.What is wrong??? Thanks to everybody who can help. CFM

[Users] failure route doubts
by Jose Silva 27 Oct '06

27 Oct '06

Hi, I'm having some doubts on how to use/do some things with dispatcher module and failure route. I'll try to explain my problem. On my main route block I select the destination (using ds_select_dst) to where I want to send the message, and indicate that responses should pass through the failure_route, I also add a header with some things that are needed by the next proxy. On the failure route when I get 408 Time Out I mark the previous destination and select the next destination. until here everything goes fine. After this I want to change the message that I'm going to send to next proxy, for this I need to remove the header that I inserted previously on the main route block and access the destination URI that the ds_next_dst updates. My first doubt is that when I print the destination URI it has the previous destination ( the one used in the main route block) but when it relay's the message it goes to the right destination (the one returned from ds_next_dst), Is there any reason for this ? I'm using $du to access it, is this wrong? My second doubt is, what sip message do I have access to in the failure route (the one I received or the one I sent out)? I ask this because I try to remove the header I inserted in the main route block and it does not remove anything but when I relay the message the header I tried to remove goes on the message. Thanks in advance, José Carlos Silva

[Serusers] some tunning to syslog messages
by Ricardo Carvalho 27 Oct '06

27 Oct '06

Hi all, Along my ser.cfg code I want to print a formatted message using LOG functions like xlog implemented with xlog module of Ser. I already can do it, but now I pretend to write in the same xlog formatted message, some formatted text that can be splitted in multiple lines. I thought that it could be done using \n sintax, like in C, but some testing made me realise that it doesn't work. I also found that this isn't a problem of xlog module of Ser, but a limitation of Syslog service because doing a simple program like this won't result like expected: ////////////////////////////////////////////////////////////////////////////////////////////////////////////// #include <syslog.h> #include <stdio.h> int main(int argc,char ** argv){ char *message = "This is a messagea and this is the rest"; int priority = LOG_INFO | LOG_LOCAL6; syslog(priority,"This is a message %c and this is the rest",13); return 0; } ////////////////////////////////////////////////////////////////////////////////////////////////////////////// The output of this program results in the same line of syslog dump. In ser.cfg if I do something like the following line, the resulting print to syslog is still written in one line: xlog("L_INFO", "===> received [%rm] request\n From URI: [%fu]\n"); Syslog simply ignores the \n parameter. Is there any other way to split xlog formatted messages of ser.cfg to be written to Syslog? Thanks in advance, Ricardo.

[Serusers] New route graph utility
by Nils Ohlmeier 27 Oct '06

27 Oct '06

Hello, in case you are not following the CVS commit log messages: I just checked in a small python script which should be able to print a dependency graph in ASCII of the route blocks of a SER config file. When you try to understand more complex configuration files this tool might be helpfull. But be warned: this is still alpha code! It will not eat your config file, but the output might not meet your expectations :-) If you run it with the default configuration file the output will look like this: ./route_graph.py ../../etc/ser.cfg Main | \- 1 | \- 1 | \- 1 | \- 1 A more complex scenario (from a config with named routes) could look like this: ./route_graph.py ./ser.cfg Main | \- ROUTE_RPC | | | \- ROUTE_ERROR_REPLY | \- ROUTE_PROXYINIT | | | \- ROUTE_ERROR_REPLY | \- ROUTE_INDIALOG | | | \- ROUTE_ERROR_REPLY | | | \- ROUTE_ST | | | \- ROUTE_FORWARD | | | | | \- ROUTE_LI | | | | | \- ROUTE_RTPPROXY | | | | | \- ROUTE_RR | \- ROUTE_DOMAINPOLICY | | | \- ROUTE_ERROR_REPLY | \- ROUTE_REGISTRAR | | | \- ROUTE_ERROR_REPLY | \- ROUTE_AUTHENTICATION | | [... omitted bigger parts...] Send routes ----------- onsend Failure routes -------------- FAILURE_ROUTE | \- ROUTE_RTPPROXY | \- ROUTE_VOICEMAIL | | | \- ROUTE_SEMS | | | | | \- ROUTE_LI | | | | | \- ROUTE_RR | | | \- ROUTE_ERROR_REPLY | [... omitted bigger parts...] Onreply routes -------------- REPLY_ROUTE Feedback is welcome. Patches even more! :-) Greetings Nils

[Serusers] memory allocation error
by Lol Zimmerli 27 Oct '06

27 Oct '06

Hello, In my ser.cfg I would like to add a lot of peers in this form: ... if (uri=~"^sip:\*123[0-9]*@.*"){ xlog("L_INFO", "Forwarding *123 to 'other.sip.com': %fu (%ua - %is) -> %tu, %mf\n"); strip(4); rewritehost("other.sip.com"); } ... If I put four of them, everything is okay, ser starts and the calls are correctly redirected. But if I put 1000 of them: Oct 27 02:55:57 ser ser: ERROR:lex:addstr: memory allocation error Oct 27 02:55:57 ser last message repeated 71 times Oct 27 02:55:57 ser ser: ERROR: mk_action: memory allocation failure Oct 27 02:55:57 ser ser: ERROR: mk_action: memory allocation failure Oct 27 02:55:57 ser ser: ERROR:lex:addstr: memory allocation error Oct 27 02:55:57 ser last message repeated 12 times Oct 27 02:55:57 ser ser: ERROR: mk_action: memory allocation failure Oct 27 02:55:57 ser ser: ERROR: mk_action: memory allocation failure Oct 27 02:55:57 ser ser: ERROR:lex:addstr: memory allocation error Oct 27 02:55:57 ser last message repeated 20 times Oct 27 02:55:57 ser ser: ERROR: mk_elem: memory allocation failure Oct 27 02:55:57 ser ser: ERROR:lex:addstr: memory allocation error I tried to change #define SHM_MEM_SIZE 32 into #define SHM_MEM_SIZE 128 in config.h, but same result. Also, in some old doc, a config item called 'shared_mem_size', but adding shared_mem_size=256 in ser.cfg just leads to a Oct 27 03:04:16 ser ser: parse error (30,1-16): syntax error I am quite sure it's just a number to change, but where?
