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.

by Olli Attila 10 Feb '17

10 Feb '17

Hello, I am running kamailio version 4.4.2. I just configured MSRP module to kamailio with example config taken from "http://www.kamailio.org/docs/modules/4.4.x/modules/msrp.html#msrp.usage" (Example 1.16. Event Route (using htable for MSRP connection tracking). After configuring msrp relay, the kamailio service has been restarted succesfully and no errors occurred. Blink is configured to use my server name with tls and port 5061 for MSRP. I get this error on Blink when i try to send files: https://p.dnaip.fi/X4vwoy40 Any suggestion what is going wrong? Cheers, -- Olli

Branching v5.0
by Daniel-Constantin Mierla 09 Feb '17

09 Feb '17

Hello, following discussion on mailing lists and at Fosdem over the last weekend, I am considering to create the git branch 5.0 later this week, on Thursday, Feb 9, 2017. Afterwards, the master branch can take commits with new features. The branch 5.0 will be tested for 1-2 more weeks and if all is fine, the v5.0.0 can be released. Should anyone have other suggestions, jump into discussion.

nathelper module fix_nated_register(); question
by JR Richardson 09 Feb '17

09 Feb '17

Hi All, Just confirming when using nathelper, the fix_nated_register function is only used to write corrected contact into to $avp then to database, this function does not actually change the contact in the SIP message when passing through the proxy, correct? fix_nated_contact is used to actually change the SIP message contact when passing through the proxy. I'm using kamailio 4.2. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope
