[Kamailio-Users] [OT] SIP ALG Detector released
by Iñaki Baz Castillo 19 Jun '09

19 Jun '09

Hi, as part of my personal battle against SIP ALG routers, I've created an utility to detect such routers: http://dev.sipdoc.net/wiki/sip-stuff/SIP-ALG-Detector It has two parts: client and server: Basically, the client node running into the LAN sends an INVITE to the server node (running in a host with public IP). The request could be modified by the LAN router if SIP ALG is enabled. The server encodes the received request in Base64 and appends it to the SIP response. The client receives the response, decodes the body and gets the request as it arrived to the server. Then it creates a diff between the original request and the the request the server node received. These differences are displayed in the screen. Both, UDP and TCP, tests are performed. The client node is coded in Ruby and should work in any operating system (if Ruby is installed). The server node is also coded in Ruby. For those interested in try it, I have a server node running in my personal server: 87.98.230.161:5060 You can test the client against my server. Feedback is welcome :) Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

[Kamailio-Users] lcr - tag value NULL prefixed as "NULL"
by Andreas Granig 19 Jun '09

19 Jun '09

Hi, Kamailio 1.5: When having gw.tag column set to NULL in db (which seems to be allowed according to db schema), then next_gw() prefixes the R-URI user with the string "NULL". Setting it to empty string (''), nothing is prefixed. I'd expect that from a value of NULL as well. Could anyone please confirm this? Also, in http://kamailio.org/docs/modules/1.5.x/lcr.html the parameter prefix_mode is missing. It's available in README.lcr though, so probably the page is out of date? Andreas

[Kamailio-Users] AVP / Odd Error
by Brandon Armstead 19 Jun '09

19 Jun '09

Hey Guys, First off thanks for any help in advance! I'm adding a single avp test i.e. $avp(s:some-avp-name) = 'foo!'; to a development configuration running Kamailio revision: 5487 (1.4.3). When I start kamailio I'm getting the following error: CRITICAL:core:init_io_wait: could not alloc epoll array As soon as I delete this AVP addition and start her back up, she starts. Code Snippet (io_wait.c) 606 #ifdef HAVE_EPOLL 607 case POLL_EPOLL_LT: 608 case POLL_EPOLL_ET: 609 h->ep_array=local_malloc(sizeof(*(h->ep_array))*h->max_fd_no); 610 if (h->ep_array==0){ 611 LM_CRIT("could not alloc epoll array\n"); 612 goto error; 613 } 614 memset((void*)h->ep_array, 0, sizeof(*(h->ep_array))*h->max_fd_no); 615 if (init_epoll(h)<0){ 616 LM_CRIT("epoll init failed\n"); 617 goto error; 618 } 619 break; 620 #endif I do not know enough of Kamailio CORE but it looks like something to do with memory allocation / file descriptors? I've increased available memory to kamailio as well as open file limits / file descriptors etc -- to no avail, any help is much appreciated thanks guys!

[Kamailio-Users] Multipart SDP problem...
by Edson - Lists 18 Jun '09

18 Jun '09

Hi, Guys... After trying a PSTN call through an AS5300-Cisco GW got this error: ==== ON-REPLY[1] incoming reply <200> for <INVITE> <8999>/<XXXXXXXXXXX> ERROR:nathelper:check_content_type: invalid type for a message ERROR:nathelper:extract_body: content type mismatching ERROR:nathelper:force_rtp_proxy: can't extract body from the message == Googling around I found an e-mail from Ovidus (23/12/2008) telling that a multi part SDP wasn't integrated on Nathelper. I suppose that I faced such an issue. How to circumvent/workaround this error message? As a side effect call gives no RTP flow, since one direction send it to RTPProxy and the other directly.

Re: [Kamailio-Users] Trying to make Purple Module work
by Eric PTAK 18 Jun '09

Hi mani, Looking your log, I see you're trying to contact sip:manivasagam.s*msn.com@ kmilo.smithmicro.com as I mentionned to be a possible way to get purple working without mapping non-sip friends. But it requires modifications in the purple_* functions to support it. Then, there is also the usrloc error cause it didn't find such user. You must use a purple_gateway_domain different from your main domain, in order to filter messages to the gateway easyly, priori to other routes. for example (but again the module need mods) : route { # initial sanity check, loopavoidance & big messages ..... ..... # retransmission absorbtion ..... ..... # messages to purple gateway if ($rd == "purple_gateway_domain") { route(10); } # main route ..... ..... } #purple route route[10] { #method filtering to call the appropriate purple function } Eric. 2009/6/16 mani sivaraman <mani.opensips(a)gmail.com> > Attached is kamailio debug log while trying to send a MESSAGE to an MSN > contact from my SIP Account. manivasaga.s(a)msn.com is the MSN account > available on the SIP Buddy list.

Re: [Kamailio-Users] disable_dns_blacklist
by Karl Smith 18 Jun '09

18 Jun '09

After the second attempt that Kamailio sends a call towards an ip address and gets a negative sip response say 503, kamailio will block that ip route for approx 4 minutes and sends 401 unauthorized immediately to the sip client. That ip route can be a gateway which is sending a negative reponse for certain destinations only and this may be due to a problem which is beyond the gateway itself; so I want to avoid blocking the complete route automatically. It appears that, in version 1.5 the route gets blocked for a longer period. Appreciate any help.

I have tried both kamailio 1.4 and also 1.5. Since Kamailio 1.4 (perhaps since OpenSer 1.3) this option is dissabled by default (disable_dns_blacklist=yes).

[Kamailio-Users] disable_dns_blacklist

Hi, I have always used the global setting disable_dns_blacklist=yes so as to avoid openser from temporarily blocking a particular route that may return a negative sip response such as 503. I am now planning a migration to kamailio but the feature does not seem to be working. I have tried both kamailio 1.4 and also 1.5. Any ideas? Thanks, Karl

[Kamailio-Users] Q value with alias_db?
by Robert McGilvray 18 Jun '09

18 Jun '09

This seems like it should be easy but based on the database schema I can't figure out how I can specify a Q value for different destinations when using alias_db with mysql. I need to map external DIDs to phones registered to kamailio and some to other gateways, sometimes those numbers will need to fork based on the q. I can probably do what I need with direct sql queries I just want to make sure I'm not missing something with db_aliases first.
