OPENSER XLOG HOW TO
OPENSER XLOG CODE

The “xlog” statements are just reminders that you will probably want to send an audio clip to the caller letting him/her know the status of the blind call forwarding operation.Īs an exercise, this example can be expanded to offer the end user the ability to just enter *21 and then be presented with a voice prompt to enter the number that calls will be forwarded to.Īnother exercise would be to offer the caller the ability to change the “call forward on no answer” and “call forward on busy” settings. There must be additional logic placed in the configuration file to actually implement the call forwarding function when an INVITE to the caller's number takes place. It just dynamically sets an AVP called fwd_blind.

This example DOES NOT implement the call forwarding function. The example also checks for and rejects recursive blinc call forwarding (attempts to blindly call forward to the same number the caller is using). The tonfailure() function tells OpenSIPS to handle the SIP failure.

If pid is also given, the logging level will change only for that process. If a logging level is given, it will be set for each process. If no argument is passed to the loglevel command, it will print a table with the current logging levels of all processes. This example assumes that only authorized users are allowed to turn on or turn off blind call forwarding. To better test and debug the routing script, we will use the xlog() function as a. Get or set the logging level of one or all OpenSIPS processes.

With the module configured, it’s time to setup the actual routing of the SIP requests.The following example shows how to “setup” and “stop” blind call forwarding from a SIP device. Modparam('lcr', 'defunct_gw_avp', '$avp(s:defunct_gw_avp)') At the bottom of that section, add the following values: modparam('lcr', 'db_url', 'gw_uri_avp', '$avp(i:709)') The OpenSER communicates with PortaSIP via the interface 212.249.15.3. Our OpenSER server communicates with Verizon via interface 195.129.125.73 for sending outgoing calls and for receiving our range of 20’000 numbers (021550abcd and 022550abcd) from PSTN. Back in the configuration file, look for the module parameters section. We have an OpenSER server running on two interfaces: 212.249.15.3 and 195.129.125.73. Now that we’ve configured Kamailio, we need to configure the LCR module.

Place debugging code 'EVERYWHERE' throughout your. Xlog command is used to print the header fields RFC-3261, pdf, unix-txt, dos-txt, p.11 of received SIP messages. We can now begin setting up the LCRs module parameters. We have found that xlog along with the debugging flag provides easy access to more than enough information to help track the execution flow and content of each message that OpenSER processes. OpenSER server OpenSER server receives SIP messages from the SIP phone. In the same config file, locate the section where it says “loadmodule” and go to the bottom of that list and add: loadmodule “lcr.so” If your Kamailio instance is behind a firewall make your line look like this: listen=udp::5060 advertise :5060Įlse if your Kamailio instance is on the public internet make it look like this: listen=udp::5060īy default Kamailio does not load the LCR module so we will need to add it. Open up your Kamailio configuration (kamailio.cfg) and look for the “listen” line. Configuring Kamailioīefore we start setting up the LCR module, we first need to make some changes to the Kamailio configuration file. First off, we will need to modify the listen parameter.

Other than a Kamailio server, you can proceed with the rest of the tutorial. All you’ll need is 2 carrier endpoints and their rates for calling a certain area code. The goal of this document is to explain how to get Kamailio to route traffic to the carrier with the least cost.
