TOPOS issue
by David Villasmil 29 Sep '20

29 Sep '20

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) Anyone ever encountered this? Is … [View More]

websocket transport protocol in Record-Route header
by Juha Heinanen 29 Sep '20

29 Sep '20

No matter if UA uses ws or wss to connect to Kamailio, when K routes INVITE from this UA and record_route() is called, K always adds ;transport=ws parameter to Record-Route URI, for example, Record-Route: <sip:192.168.43.83:7998;transport=ws;r2=on;lr> In this test, Kamailio is listening on that port like this: # SIP over WebSocket listen=tls:192.168.43.83:7998 Why doesn't K in this case add ;transport=wss to the R-R URI? -- Juha

uac_replace_from function
by Ilie Soltanici 29 Sep '20

29 Sep '20

Hello, The uac_replace_from seems not to be working properly in the ver 5.4. This is the header I'm trying to change: *From: "Admin" <sip:+123456789@local.ip>;tag=as11428589* by using this function: uac_replace_from("","sip:+123456789@domain.com"); I'm getting the following header: *From: <sip:+123456789@domain.com35316853757>;tag=as11428589* (Double space in the callerid name, and number appended after the domain) Thank you.

A possibility to disable the topology hiding for some destinations.
by Leonid Fainshtein 29 Sep '20

29 Sep '20

Hi, The 'topos' module has a very useful "event_route[topos:msg-sending]" option that allows very easily to disable topology hiding for ITSPs that requires the real data in the Contact header field. It looks like the feature is not supported in the 'topoh' module (ref. https://kamailio.org/docs/modules/5.4.x/modules/topoh.html). The available 'event_route[topoh:msg-outgoing]' option requires defining the remote server IP address (or a list of addresses in some cases) that is not always … [View More]

Received parameter on Via
by Duarte Rocha 29 Sep '20

29 Sep '20

Greetings, When NAT is detected in my Kamailio, the proxy add the parameter "received" to the Via header which includes the source IP. What is the mechanic or function responsible for this behaviour? Does it come from the NATHELPER module? Best Regards,

Rewrite BYE to Cancel
by Lars Olsson 29 Sep '20

29 Sep '20

hi, I have a Kamailio setup infront of a SIP system that do not handle cancellation of a INVITE correctly. The system sends out a BYE request instead of a Cancel request on non connected dialogs. I am trying to find a way to let Kamailio "translate" the BYE request to a Cancel reqeust for the ongoing INVITE dialog. Alternative if SEMS b2bua can do it, but currently it replies: "not sip-relaying BYE in not connected dlg", and I have not found any obvious way to rewrite it there. Any thoughts.… [View More]

Trying to use xavu with "two level naming"
by Chaigneau, Nicolas 29 Sep '20

29 Sep '20

Hello, I'm trying to use xavu as described in Kamailio documentation: https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#xavu_id_-_xav… $xavu(a=>b) = "xyz"; # <- two level naming supported However, this does not seem to work. The second level is ignored. When calling pv_xavu_print() it only shows the last element set, e.g.: $xavu(cdru=>one) = "one" ; $xavu(cdru=>two) = "two" ; pv_xavu_print() ; Result: 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [… [View More]
