Hello, I added a bunch of new variables to deal easier with next hop address and be able to retrieve micro-seconds in the config file.

[Kamailio-Users] Problems with snmpstats in Kamailio-3.0.0

by Santiago Gimeno

Hi, I'm trying to migrate from K-1.5 to K-3.0.0 and I'm having problems loading the snmpstats module in kamailio-3.0.0. The error is: ERROR: <core> [sr_module.c:390]: ERROR: load_module: could not open module </usr/local/lib/kamailio/modules_k/snmpstats.so>: /usr/local/lib/kamailio/modules_k/snmpstats.so: undefined symbol: module_loaded By checking the code it looks like module_loaded function is not implemented in sr_module.c anymore. Could this be the problem? Thanks. Best regards, Santi

[Kamailio-Users] Request for a special parallel serial forking scenario

by Klaus Feichtinger

Hi Kamailio users, I have a special question regarding a mixture of serial and parallel forking, operated by Kamailio-3.0.0. First of all I will give you a short background information, what the target will be: I have a SIP-server on place A, 3 gateways on place B and 3 gateways on place C). All (6) gateways are registered with the same username on SIP server (A), but with different Q-values (e.g. GW-B1=1.0, GW-C1=1.0, GW-B2=0.8, GW-C2=0.8, GW-B3=0.6, GW-C3=0.6). The target is, that a call for a gateway MUST be signalled on gateway(s) of place B and C in parallel (forking) until the call is finally established over one of the two involved gateways on place B or C. When (one of) the prime gateway(s) (with the highest Q-value) fail (e.g. they do not send a provisional response within a timeout or send a negative response), the next gateway(s) should be addressed (with the next lower Q-value), a.s.o. The parallelism for signalisation on place B and C is necessary, because of redundancy / safety reasons. Configuration for serial forking is done as described in the README of the TM module. It is a mixture of the main route and a failure_route in combination with the functions t_load_contacts() and t_next_contacts(). The loaded contacts for serial forking differ (from standard scenarios) in that way, that each sequential target consists of a pair of "users" instead of a single user. This configuration works well in case that both gateways on place B and C fail at the same time (BOTH do not send a response or BOTH send a negative response or one does not send a response and the other one sends a negative response). However, in case that only ONE of the two (always in parallel) addressed gateways fails, it does not work as expected. It does nothing and/or waits for an eventually negative response or the call setup timeout. Only then the next gateway-pair will be addressed. => is the behaviour of TM correct/"as designed" to make an AND-relation with both branches and access the failure_route only then, when both branches fail? Does anybody have an idea how this problem could be solved or any alternative solution for this special requirement of parallel signalisation in any case? Thanks in advance!

[Kamailio-Users] TM module

by Denis Putyato

Hello everybody! ERROR: tm [tm_load.c:47]: tm:load_tm: Module not initialized yet, make sure that all modules that need tm module are loaded after tm in the configuration file Kamailio 3.0 was installed from GIT. Kamailio starts success. But the error appears. I think because of this I have a problem with making a call through kamailio. Calls were failed because kamailio send CANCEL or 487 code immediately after send INVITE to some outgoing gateways (after t_relay() has been made). Is this really need load all modules for tm working properly? I read documentation and fount that almost all modules that need tm loaded do not need in my config. Thank you for any help.

[Kamailio-Users] Dynamic setting of dispatcher route set

by Alex Balashov

Unfortunately, ds_select_dst()/ds_select_domain() do not seem to take PVs for their first argument (the route set ID from which to choose). Is there any workaround for this, e.g. when the route set is indeterminate until runtime? It would be very inconvenient to have to work around this by implementing own rollover logic when the dispatcher module is so good... perhaps the possibility of a quick and easy patch to the git trunk?
