Kamailio IMS with custom AVPs
by Gaston Siffert 28 Jul '20

28 Jul '20

Hello all, I am investigating on how to integrate few IMS modules in the Platform I am working on. At the moment the main drawback for me is to find a way to export data from the Diameter Answers. In the RFC 7155, it’s written that the AA-Answer could have a list of customisable fields. While looking at the implementation of the Rx_AAR (IMS QOS) in Kamailio, the module does not seems to export any of the fields from the AA-Answer except the return code. The same applies for the implementation of I_perform_location_information_request (IMS ICSCF) in Kamailio. Do you have any recommendation on how to export the other AVPs from the Diameter Answers ? Instead of IMS QOS and IMS ICSCF, I could use diameter_request_async (IMS Diameter Server) to make my own AAR and LIR, but is it the recommended practice ? https://tools.ietf.org/html/rfc7155#section-3.2 <https://tools.ietf.org/html/rfc7155#section-3.2> https://kamailio.org/docs/modules/5.0.x/modules/ims_qos.html#idp18760852 <https://kamailio.org/docs/modules/5.0.x/modules/ims_qos.html#idp18760852> https://kamailio.org/docs/modules/4.4.x/modules/ims_icscf.html#idp39432196 <https://kamailio.org/docs/modules/4.4.x/modules/ims_icscf.html#idp39432196> https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_server.htm… <https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_server.htm…> Best regards, Gaston Siffert

Using GeoIP2 AS Lookup?
by Mark Boyce 27 Jul '20

27 Jul '20

Hi all Just looking at the latest GeoIP2 MaxMind databases (now requires registration, but still free) and noticed that they also include the AS (ISP) lookup one in the free offering. Wondering if this is another way to facilitate better security for users on dynamic IP. Typically working from home these days. So, rather than just limiting an end device to a country we could limit it to a particular ISP within that country. Has anyone tried this? Have I missed a reason why this wouldn’t help? Admin overhead not worth it? Thoughts? Best regards Mark -- Mark Boyce Dark Origins Ltd

kamailio 5.3.5 - none local route header
by Jonathan Hunter 27 Jul '20

27 Jul '20

Hi Guys, Sorry if this is too generic or silly a question but I am testing kamailio 5.3.5 within Azure and its behind NAT. I am having an issue with passing an ACK from our internal side back out to the carrier side and it appears having run loose_route a none local route-header is consistently being removed by kamailio at this point. ie Route: <sip:CARRIER_IP;lr> Is this normal or configuration related? As I am unsure within what scenario I would remove a route header which doesnt contain the local Proxy IP. Please can someone advise? Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Redis error: Server closed the connection / nbd_redis / kamailio 5.3.5
by Karsten Horsmann 27 Jul '20

27 Jul '20

Hi everyone, I get some strange errors from nbd_redis but my setup is working. kamailio 5.3.5 on CentOS 7.7.1908. Redis-Server is an haproxy frontend that pushed the stuff to an redis-sentinel cluster (with and really old version redis-3.2.1-2.el7.remi.x86_64). Any ideas on that?
