app_python not able to import from Router
by Örn Arnarson 02 Jun '14

02 Jun '14

Hello, I've tried installing kamailio both from deb and from source (4.0.4 in both cases) on Ubuntu server 14.04. In both cases, I'm having problems with importing from the Router module in python, which I presume is made available when invoked from kamailio with the python module loaded. Here's what I see when trying to start kamailio with a python script with "from Router import LM_ERR": May 28 16:34:13 vcr01 kamailio: NOTICE: <core> [sr_module.c:627]: load_module(): /usr/lib/x86_64-linux-gnu/kamailio/modules/app_python.so: exports dlflags interface is deprecated and it will not be supported in newer versions; consider using mod_register() instead May 28 16:34:13 vcr01 /usr/sbin/kamailio[19652]: INFO: rr [../outbound/api.h:49]: ob_load_api(): Failed to import bind_ob May 28 16:34:13 vcr01 /usr/sbin/kamailio[19652]: INFO: rr [rr_mod.c:159]: mod_init(): outbound module not available May 28 16:34:13 vcr01 /usr/sbin/kamailio[19652]: ERROR: app_python [python_support.c:132]: python_handle_exception(): mod_init: Unhandled exception in the Python code:#012Traceback (most recent call last):#012 File "/etc/kamailio/callrouting.py", line 2, in <module>#012 from Router import LM_ERR#012ImportError: cannot import name LM_ERR May 28 16:34:13 vcr01 /usr/sbin/kamailio[19652]: ERROR: <core> [sr_module.c:939]: init_mod(): init_mod(): Error while initializing module app_python (/usr/lib/x86_64-linux-gnu/kamailio/modules/app_python.so) I load the module so: loadmodule "app_python.so" and set the following parameters: modparam("app_python", "script_name", "/etc/kamailio/handler.py") modparam("app_python", "mod_init_function", "mod_init") What am I doing wrong? Am I missing some additional modules from kamailio? handler.py is just the sample python script provided with the package. Any pointers appreciated. Regards, Örn

JSSIP with Kamalio with SIP end points
by Steve Ng 02 Jun '14

02 Jun '14

Hi, My users are from a web application using JSSIP. They each have a sip trunk account, which could be from any provider. JSSIP would connect to Kamailio's websocket server passing the SIP trunk credential information and Kamailio will relay it to that specific sip trunk provider? Is there anyway that I could use Kamailio as the middleman? Is it a combination of dispatcher module and websocket module? Thanks! Regards, Steve

drouting failure loop
by Pete Ashdown 02 Jun '14

02 Jun '14

I'm trying to get my head around how to do a failure loop in droute through all possible destinations, and if all destinations are exhausted, go to failureroute. Does anyone have an example of this? Without the ability to do a while on (!t_relay()) to determine whether to go to use_next_gw(), I'm not sure how I can. Thanks in advance.

Use of received=X.X.X.X param in Contact header of REGISTER message
by Luis F Urrea 30 May '14

30 May '14

Hi all, I have an existing Kamailio installation that is handling registrations and NAT traversal for clients. There is one particular build of softphone that sends us a received=X.X.X.X param in its REGISTER message and it seems that the current Kamailio's config in place always uses that address to store the AOR. It happens to be that the client appears to be misbehaving and sending an outdated IP address on that field. My question is where in the NAT traversal functions do I have control over using this param or not. TIA

Problems migrating from rtpproxy/rtoproxy.so to rtpproxy-ng/rtpengine

Hi all, I'm currently running a pilot with kamailio 4.1.3 stable, and I would like to test WebRTC Capabilities. Websockets Support is runnig OK, and now I'm trying to deal with calls between WebTRC and legacy softphones. I have installed rtpengine (as it a replacement for old mediaproxy-ng), and it is running: rtpengine --table=0 --ip=192.168.0.197 --listen-udp=127.0.0.1:12222 As a first step, I'm trying to migrate the standard NAT handling configuration to the new module. (...) #loadmodule "rtpproxy.so" loadmodule "rtpproxy-ng.so" (...) #modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7624") modparam("rtpproxy-ng", "rtpproxy_sock", "udp:127.0.0.1:12222") NAT hanling is not working, and I catched this message from /var/log/syslog May 28 18:55:35 kamailio rtpengine[2474]: Failed to properly parse UDP command line '4547_3 d7:command4:pinge' from 127.0.0.1:60874, using fallback RE May 28 18:55:35 kamailio rtpengine[2474]: Failed to properly parse UDP command line '4545_4 d7:command4:pinge' from 127.0.0.1:57236, using fallback RE And from Kamailio's log: May 28 19:23:47 kamailio /usr/local/sbin/kamailio[4868]: ERROR: rtpproxy-ng [rtpproxy.c:1425]: rtpp_test(): proxy responded with invalid response May 28 19:23:47 kamailio /usr/local/sbin/kamailio[4869]: ERROR: rtpproxy-ng [rtpproxy.c:1425]: rtpp_test(): proxy responded with invalid response Is rtpproxy-ng module compatible with rtpengine?
