record_route() function
by Andy Chen 15 Feb '17

15 Feb '17

Hi all, I need some advise on how to use the record_route() function. So I make that call when the first method comes in and there are two Record-Route headers created. However, one of of the headers I want to add transport=tcp. What is the best way to do this? I've tried adding that string per documentation within the () and added it to both. Thanks. -- Andy Chen

Branch 5.0 created
by Daniel-Constantin Mierla 15 Feb '17

15 Feb '17

Hello, the GIT branch 5.0 has just been created, it will host the release series 5.0.x. To get this branch from GIT, you can use: git clone https://github.com/kamailio/kamailio.git kamailio cd kamailio git checkout -b 5.0 origin/5.0 Hopefully before the end of the month the full release of 5.0.0 will be out. >From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 5.0. No new features can get in branch 5.0. Enhancements to documentation or helping tools are still allowed. If you are not sure about doing or not a backport, ask on sr-dev mailing list.

Dispatcher and "src based" routing algorithm
by Olli Attila 15 Feb '17

15 Feb '17

Hello, I am using kamailio 4.4.3 (x86_64/linux) 5a2195 and Dispatcher module to route calls towards PSTN (4 pstn gateways). The Dispatcher module is using round robin mechanism to select the pstn gateway. I have built a routing logic in a way that when call arrives to Kamailio from one of the PSTN gateways, and fails to route towards an external sip target, the call is marked as CFU call (a diverting call) and routed back to PSTN with different B number, but the actual challenge is that I would like the target PSTN gateway _not_ to be the same PSTN gw from where the call originally came in to Kamailio. This feature is requested because of the technical limitations of the pstn gateway software. So is there any mechanism in Dispatcher or elsewhere in Kamailio to do this? Basically I would need a flag or something to mark the pstn gateway when the call comes in and assure that when routing back to pstn, the same gateway would not be used at all, or it should be used as last target from the four gateways in Dispatcher. Cheers, -- Olli

Refreshing: info about private emails
by Daniel-Constantin Mierla 15 Feb '17

15 Feb '17

As I still receive a lot, I am re-posting the notification about private emails, either initiating a topic or sent directly after a discussion started on public mailing lists (subject with mailing lists prefix, but the sender header is not the mailing list daemon). I would like to remind that, at least in my case, writing emails directly without cc-ing the mailing list is highly not recommended. The rule is also suggested in the mailing lists presentation page: - http://www.kamailio.org/w/mailing-lists/ Unless I asked explicitly for a private email with some specific details, the message will not be noticed in decent time and therefore not replied. I use this email address for many public mailing lists and it is intended only for that usage, I am reacting based on the filters I created, unmatched messages getting the lowest priority. Therefore if you wrote me and expect a response, re-send the message to the appropriate public mailing list. Checking and answering the messages on Kamailio mailing lists are among the top of priorities on my daily activity, so it is high chance you get the response faster when you write there. Note that you can always mask sensitive data (e.g., replace passwords, IP addresses) before sending logs or config file. There are several common sense as well as technical reasons for keeping the discussion on public mailing lists. Here are some along with other suggestions to improve the likeliness of getting an answer: - we are not answering questions on mailing lists to help only one person, but also other people that may have similar issues in the future -- they can find the answers in the archive with a search engine. Also, other people subscribed to the list can learn from conversation or contribute to the discussion, resulting in better outcome - the amount of unexpected messages is very high -- it is practically a zero chance to get to the folder with messages that didn't match any filter (thus your message is not going to be replied) - whenever I find time, the first emails I answer are those coming on mailing lists. They are many there as well, people are traveling or having other personal or business projects, so sometime is good to send a reminder if a question does not get an answer - starting with negative approach or no technical content, like you are going to use something else if you don't get this instantly, or this application is missing what so ever tutorial giving exactly the solution you need, or simply asking for full config of complex requirements, is not helping at all, but actually making people to ignore your messages. Start with what you tried and where you got stuck. Everything you get is for free, have appropriate expectation and behavior.

Hello, I'm using TOPOH module but I have a problem with Call-ID. If I use: modparam("topoh", "mask_callid", 1) and send the INVITE to a media server, when media server send BYE to KAMAILIO, Kamailio answer like transaction not exist. In the parameter description, I read i have to use "lreq_callee_headers" dialog parameter to resolve this kind of issues, but I can't find this parameter on the module description. I'm using Kamailio 4.4.5 Thank's Regards

python_exec and parameters
by gmele 10 Feb '17

10 Feb '17

Hello, in our Kamailio, we are using python_exec to execute script used to send push notifications to Google or Apple. Currenty, the method we call only accepts the message as parameter. We then extract from the message the Call Id, to URI and from URI. Here is the python method signature: *def SendPushNotification(self, msg)* To extract the toUri and fromUri (and remove the sip:), we use python regex : *uriPattern=re.compile(".*sips?:(.+@[^>;]+)")* This is working well 99% of the time, except sometimes (we don't know why) where we get the error: *logger_LM_ERR(): Exception occurred: Traceback (most recent call last): File "mypythonExample.py", line XXX, in SendPushNotification requestUri = self.ExtractURIFromHeader(msg.getHeader("to")) File "mypythonExample.py", line XXX, in ExtractURIFromHeader m= self.uriPattern.match(header); TypeError: an integer is required* We tried to analyze the cause of this error, but we didn't find any problem with the message itself (the message is complete, with the *to *and *from *correctly filled). So, to avoid using the python regex, we have decided to pass parameters to the python script (callId, from and to URI): *def SendPushRequest(self, msg, fromUri, toUri, callid)* But it seems python_exec doesn't support more than 2 parameters ($mb and another one). Is this exact? If this is the case, how can we pass several parameters from kamailio.cfg? Thx for your help.
