Hi! I’m trying to get SDP body in my var. I’m using smth like this if (KSR.textops.has_body() ~= -1 and KSR.textops.has_body_type("application/sdp") ~= -1) then KSR.textops.get_body_part("application/sdp", "$var(pbody)») local sdp_body = KSR.pv.get("$var(pbody)") …. end But in logs i see this LUA {INVITE}: 7(20794) DEBUG: <core> [core/parser/msg_parser.c:183]: get_hdr_field(): content_length=470 LUA {INVITE}: 7(20794) DEBUG: app_lua [app_lua_sr.c:1496]: sr_kemi_lua_exec_func_ex(): param[0] for: has_body_type is str: application/sdp LUA {INVITE}: 7(20794) DEBUG: textops [textops.c:3083]: has_body_helper(): content type is 196611 LUA {INVITE}: 7(20794) DEBUG: app_lua [app_lua_sr.c:1496]: sr_kemi_lua_exec_func_ex(): param[0] for: get_body_part is str: application/sdp LUA {INVITE}: 7(20794) DEBUG: app_lua [app_lua_sr.c:1496]: sr_kemi_lua_exec_func_ex(): param[1] for: get_body_part is str: $var(pbody) LUA {INVITE}: 7(20794) DEBUG: <core> [core/pvapi.c:396]: pv_cache_lookup(): pvar [$var(pbody)] found in cache LUA {INVITE}: 7(20794) DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header LUA {INVITE}: 7(20794) INFO: <core> [core/msg_translator.c:1694]: get_boundary(): Content-Type hdr has no params <application/sdp> LUA {INVITE}: 7(20794) ERROR: textops [textops.c:2468]: ki_get_body_part_helper(): Cannot get boundary.

How to extract SIP-I ISUP parameters
by Eugene Prokopiev 02 Apr '18

02 Apr '18

Hi, I need to extract ISUP parameter 'Redirecting number' from SIP-I INVITE request and add it as SIP header with 'X-' prefix to process in FreeSWITCH. I tried to read https://kamailio.org/docs/modules/5.1.x/modules/sipt.html (but it is about updating headers) and https://kamailio.org/docs/modules/5.1.x/modules/ss7ops.html (but I have only ISUP encapsulated in SIP), so not found any solution. Help me to find it please. -- WBR, Eugene Prokopiev

audio issues
by Atux Atux 02 Apr '18

02 Apr '18

Hi. I am doing my first steps with Kamailio and i have installed it according to the http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour. i did create 3 users 1100,1101,1102 and then in windows PC i did install the jitsi application. Even though the accounts on Jitsi show as online on each PC i have audio issues. All PCs are in the same LAN -Device 1101 calls 1102 and on 1102 i cannot hear anything. 1102 talks and it cannot be heard -Device 1102 calls device 1101 and on 1101 PC i hear a ringing tone. Then i answer from 1101. 1102 speaks and it can be heard, not the other way around. any ideas, please?

KEMI and SQL - best practices
by Igor Olhovskiy 02 Apr '18

02 Apr '18

Hi! Is there any suggestions, best practices of using SQL connections in KEMI? Main idea - not to open connection to database in every route (cause it’s really expensive operation in terms of time) and reuse existing, for ex, created in some kind of startup route? Or maybe use some else technique? Regards, Igor

Re: [SR-Users] How to determine correct port to set in record-route header
by Pranathi Venkatayogi 30 Mar '18

Any help? From: Pranathi Venkatayogi Sent: Monday, January 23, 2017 2:35 PM To: 'Kamailio (SER) - Users Mailing List' <sr-users(a)lists.sip-router.org> Subject: How to determine correct port to set in record-route header Hi, I am using Kamailio behind NAT, unable to figure how to make it put “public ip” in Record-route header, I am manually inserting the hard-coded header myself as below. However now I am having trouble choosing the right port number in all scenarios. $var(dstPort) = 5061; if (dst_port==5060) { $var(dstPort) = 5060; } insert_hf("Record-Route: <sip:MY_PUBLICIP_ADDR:$var(dstPort);transport=tls;lr;nat=yes>\r\n", "Record-Route"); In one scenario I see the conflicting port numbers in “via” header vs “Record route”. The ACK is being set to port 5060 based on Record route header and is not being received by the callee. 2017-01-23 14:52:49.970233 [blink.exe 2780]: SENDING: Packet 11, +0:00:36.411867 10.0.27.108:58217 -(SIP over TLS)-> 172.31.211.31:5061 SIP/2.0 180 Ringing Via: SIP/2.0/TLS 63.149.103.72:5061;received=172.31.211.31;branch=z9hG4bK4799.7067bd2a48063748a4c353fa408eaefa.0 Via: SIP/2.0/UDP 10.0.16.52;rport=5060;branch=z9hG4bK4799.935a27c6ef5ad112225964cbe7c1be44.0;i=2 Via: SIP/2.0/TLS 10.11.200.12:51793;rport=51793;received=10.11.200.12;branch=z9hG4bKPj49f6aeca3f9b4155ab4c5304b544aa4d;alias Record-Route: <sip:63.149.103.72:5060;transport=tls;lr;nat=yes> Record-Route: <sip:10.0.16.52:5061;transport=tls;lr;nat=yes> Call-ID: 09ce10efa6a946bf9445ccc21857393e From: "cust1" <sip:cust1@devtranslation.sms-test.cyracom.com>;tag=95082caabecc42548c2fec5ccd29e5de To: <sip:spanish@translation.sms-test.cyracom.com>;tag=ec365cc8489b48a7bc5725d21b7d97a1 CSeq: 17422 INVITE Server: Blink 3.0.0 (Windows) Contact: <sip:20745891@10.0.27.108:58216;transport=tls> Allow: SUBSCRIBE, NOTIFY, PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, MESSAGE, REFER Content-Length: 0 Questions: 1. How can I let in-built record-route function automatically choose “public ip” so I can get rid of my manual insertion altogether. 2. If no option, what is the right way to choose the port on which packet is being received, so it is same as what is on “VIA”. 3. Any other pointers to improve the logic here?
