IMS early media
by Tsvetan Filev 31 Jan '19

31 Jan '19

Hi all. I want to use SIP early media to play music to the caller in kamailio IMS installation like this: http://www.sharetechnote.com/html/IMS_SIP_EarlyMedia.html I looked a little bit but didn't find ready solution. The information is vague on this topic. Should this be done through a module or application server ? May I need to handle ringing in onreply_route and send OK with SDP to the caller in SCSCF ? Regards.

AWS binat external -> internal routing and record_route
by Dmitry Sytchev 17 Jan '19

17 Jan '19

Hi all! I have a question that arises in mailing list sometimes, but it is still not clear for me how to work with this. We have AWS instance with standard Amazon bi-nat, so basically communication with external hosts works with listen udp:ip:port advertise ip:port But in case when we need to send external call to internal network by internal ip addresses, we want to have internal host in record-route. As far as I understand, basic recommendation is to use separate port or internal address and select it with appropriate function. Maybe it is more theoretical question, but can we do something to generate correct record-routes and VIA for calls coming from external network to make their softswitches happy, and still maintain internal address in messages going to internal hosts, using single host and port on Kamailio behind nat? Thanks! -- Best regards, Dmitry Sytchev, IT Engineer

"Discarded invalid SRTP packet: authentication failed" warning
by David Cunningham 10 Jan '19

10 Jan '19

Hello, We're having an issue with rtpengine (used by Kamailio) where audio works initially, but then after an apparently random amount of time stop working. We see that when audio stops working rtpengine logs this: Dec 10 09:58:57 hostname rtpengine[376]: WARNING: [Pl1SeGDssOsDNWQdvey4lg.. port 48766]: Discarded invalid SRTP packet: authentication failed It then logs similar messages until the call hangs up. No such messages were logged while audio was working. Searching for this error message suggests that a change in the SSRC can cause the problem, but we don't see any such change in the PCAP. The source IP, port, codec, and SSRC all stay the same, and the Sequence increments as normal. Does anyone have suggestions on where to look next? We can share the PCAP privately if that would help anyone. Thanks for any advice! -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

Dispatcher probing
by Duarte Rocha 07 Jan '19

07 Jan '19

Hey. I have another question regarding the Dispatcher Probing. In my SBC, a Gateway is defined by it's IP, Port and SAP (Kamailio's IP used for signaling). Those 3 parameters are defined in the Gateway table. In this case ( using Options for probing), i only have access to the destination IP ($dd) and Port ($dp). I need to know the SAP associated to the gateway that is currently being probed, in order to force the correct socket in the OPTIONS request. Is there any way to get more info about the db line that is being read by dispatcher for the probing? If that's not possible i was thinking about querying my db for the Ip:Port pair and if i got more than one result, do forking using the the SAPs in the results, sending multiple OPTIONS through the multiple sockets. In this case, if only one of the OPTIONS is answered, will the gateway still appear as "Active" ? Best Regards, Duarte Rocha
