Hi, i'm newbie in kamailio, I tried installed ims kamailio from ng-repository packages, Then when I tried to send register to SIP server using SIPp, I received this log [Proxy-CSCF][28505]: ERROR: <core> [core/parser/msg_parser.c:331]: parse_headers(): bad header field [(null)] [Proxy-CSCF][28500]: ERROR: <core> [core/parser/msg_parser.c:331]: parse_headers(): bad header field [(null)] [Proxy-CSCF][28496]: WARNING: <core> [core/receive.c:192]: receive_msg(): parsing relevant headers failed [Proxy-CSCF][28505]: message repeated 2 times: [ WARNING: <core> [core/receive.c:192]: receive_msg(): parsing relevant headers failed] [Proxy-CSCF][28492]: ERROR: <core> [core/parser/msg_parser.c:675]: parse_msg(): ERROR: parse_msg: message=<#002#020#002#021#023�#023��z'��z'#006��[%�#007> Thank you -- Nguyễn Tiến Hưng

Diversion headers access and message too long error
by Joan Salvatella 01 Nov '18

01 Nov '18

Hello, We are working on a project that's using a Twilio SIP trunk that diverts calls from the PSTN to our cluster that is hosting two active-active Kamailio 5.1 instances that redirect traffic to several Asterisk 15.4 instances. On this setup we are facing 2 issues: - *Diversion headers access: *Currently, Kamailio only supports access to the last diversion header but since we are receiving traffic from Twilio (it sets the last Diversion header) we are unable to see if the caller was diverted to our SIP trunk. Is there a workaround for this? Any external module that would support this use case? - *Message Too Long Error:* Since Twilio uses long URIs to define its resources, the SIP messages being handled by Kamailio are sometimes too big and generate a "Message Too Long error". I have been able to temporarily patch this removing unused headers using remove_hf_re and remove_hf but it still fails from time to time. Is there a way to split the UDP packet to mitigate this issue? or what other options could be considered? Thanks and regards,

Topos on high load
by Igor Olhovskiy 01 Nov '18

01 Nov '18

Hi! We’ve run into really interesting issue while testing Kamailio with sipp (15 CPS, 300 calls - 1 failed call, more CPS - more failed calls) with topos involved. And at some point Kamailio starts to send 2 packets on received INVITE. 1 - with topos applied, 1 - with not. Main problem is to collect logs at this point, cause load is really high. Is it possible some internal race condition while topos involved? PCAP is attached. I’ve made a picture to illustrate a bit an issue Regards, Igor

Determine destination address family
by Isaac 31 Oct '18

31 Oct '18

Hello, How can I determine the address family (IPv6 or IPv4) of a destination? The destination in this case is a hostname. I'd like to set a flag if the destination is IPv6 but not sure how to go about it. Thanks, Isaac

USRLOC db_mode=4 and server_id
by Darren Williams 31 Oct '18

31 Oct '18

I am currently using multiple instances of Kamailio with a common database and using the usrloc module with db_mode=4 and server_id to filter the contacts that get loaded at startup on each server. The problem I seem to have is that using the RPC call ul.add, I cannot see any parameter to send to specify the server_id. The server_id that the contact is given is 0. If I manually go into the db and modify the server_id everything works as expected. I think I must be missing something somewhere as I'm sure you shouldn't need to do this. Can anyone help please. Thanks Daz

help with regex extracting from $rb
by Sergiu Pojoga 31 Oct '18

31 Oct '18

Hi there, May be some regex gurus can help me out. Being aware that regex's are tricky but not seeing another alternative in this particular case. Trying to extract MOSLQ field from $rb. $var(moslq) = $(rb{re.subst,/.*MOSLQ=([0-9].[0-9])\s+MOSCQ=([0-9].[0-9]).*/\1/s}); Above regex works fine IF body contains a single matching line. However, if there's 2 lines as in the below example - it return $var(moslq)=0.0, the last found value. I need only *LocalMetrics *values, so I tried this regex which works fine in regex101.com with flag 'multi-line' and *without flag 'global'*, but doesn't work in Kamailio. $var(moslq) = $(rb{re.subst,/.*MOSLQ=([0-9].[0-9])\s+MOSCQ=([0-9].[0-9])[\nRemoteMetrics]?.*/\1/s}); Assuming $rb is as follows: VQSessionReport CallID:1ca9258d285a539e3c1048205bf38d41@mypb.net LocalMetrics: Timestamps:START=2018-10-29T15:04:38Z STOP=2018-10-29T15:06:13Z QualityEst:EXTRI=127 MOSLQ=4.2 MOSCQ=4.4 RemoteMetrics: Timestamps:START=2018-10-29T15:04:38Z STOP=2018-10-29T15:06:13Z QualityEst:RCQ=0 EXTRI=0 MOSLQ=0.0 MOSCQ=0.0 Thanks in advance.

Hi, We are planning to upgrade our Kamailio infrastructure to Kam 5.1.6 using Ubuntu 18.04.

How is ruid calculated
by Kjeld Flarup 28 Oct '18

28 Oct '18

I got two tablets registering with the same username, this used to work but now I got a bug report that only one of them gets a call. I found out that the problem is in the ruid column as they both end up with this ruid value uloc-1-5bd0abe9-83c-e4 How is that ruid value calculated, and how can I change this? -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 49 Den ikke akademiske hjemmeside for liberalismen - www.liberalismen.dk
