by Patrick Karton 24 Jun '22

24 Jun '22

hello is there a cleaner/fastest way to update PAI header user part other than using subst i come up with subst('/^P-Asserted-Identity:(.*)(sip|sips|tel|tels):([^@]*)@([a-zA-Z0-9.]+)(.*)$/P-Asserted-Identity:\1\2:$var(newPAIUser)@\4\5/ig'); Thanks.

Append (not replace) line to SDP body
by Benoît Panizzon 24 Jun '22

24 Jun '22

Hi Gang Next question. I have some broken CPE which do not set a=ptime despite using 20ms which then causes the call to get rejected in certain destinations, because ptime header is missing. So I would like to match the user-agents in question and add back a=ptime:20 Google searches found an user with the exact same problem almost 10 years ago and Daniel replying that indeed a function to add a body line would be handy. https://www.kamailio.org/docs/modules/devel/modules/textops.html How could this be accomplished? I don't see a add_body_line or other function which does not 'replace' a body line. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Finding advertised address of socket
by Tor Petterson 24 Jun '22

24 Jun '22

Hi I have a setup where Kamailio is connected to several telephony providers using different IP addresses to communicate with them. So I have a socket per provider. I am using the dispatcher module to route calls to the different providers. My question is if there is a way to get the advertised address of the socket chosen by dispatcher? I have a socket pointer in the XAVP, but I can't figure out if it is possible to get the advertised address from it somehow. Thanks in advance. Tor

Testers wanted for new TLS transport based on wolfSSL
by Richard Chan 24 Jun '22

24 Jun '22

Hello Kamailio users, I would like testers to try out a new module tls_wolfssl, an alternate TLS transport based on wolfSSL. Why another TLS transport implementation? The travails of using OpenSSL >= 1.1.1 in Kamailio’s multi-process paradigm has been documented by OpenSIPS (and that sister project has implemented tls_wolfssl). Essentially, OpenSSL makes no concessions to the multi-process use case and in fact has implementation details that work against global shared memory structures. As a result Kamailio contains some tricky code * a pthread polyfill in core * duplicated SSL_CTX per worker * atexit workaround How to test? The code is currently in master and can be built in the usual way. Debian has 5.2.0 libwolfssl-dev needed; for some RPM distros (el8, el9, fc36) I have created a Copr repository https://copr.fedorainfracloud.org/coprs/beaveryoga/wolfSSL/ Known limitations The current state can be considered as identical to tls+OpenSSL 1.1.1/3.0.x. Old TLS protocols < 1.2 and cipher list configuration don’t work, i.e., only TLS 1.2 and 1.3 work with the default cipher list. In your configuration just replace loadmodule “tls.so” with loadmodule “tls_wolfssl.so” The rest of the TLS configuration can remain unchanged unless you are using a funky protocol version/cipher list combination. Thanks! S-P

If I turn on my firewall service, all packets will be dropped. I have to have this firewall [image: photo_2022-06-12_17-44-48.jpg] thanks for help me

Possibility of mirroring the rpm/deb.kamailio.org repos efficiently via rsync?
by Malte Schmidt 23 Jun '22

23 Jun '22

Hello, is there an rsync endpoint available or is there a possiblity of setting this up? Creating a mirror via HTTP is a rather quick and dirty solution and while the deb-repo can be mirrored using debmirror, the rpm repo is hard to sync to a non-CentOS-based machine due to missing dependencies such as yum and reposync in latest Debian-based systems. Would be great to get some input in regards to this topic. Cheers

What is the alignment of shm_malloc and friends?
by Richard Chan 22 Jun '22

22 Jun '22

Hi Daniel and kamailio users, In my integration adventure of wolfSSL and kamailio I have encountered an alignment issue sometime causing segfaults. May I enquire what is the alignment of shm_malloc and friends? The wolfSSL library integration requires that ser_malloc and ser_realloc return values aligned on alignof(_max_align_t) which in the case of x86_64 is 16. Thank you Shih-Ping

Hi all Any chance of Ubuntu 22.04 LTS "Jammy Jellyfish” being added to the Jenkins package builder for kamailio 5.6? Ubuntu native repo seems to have 5.5 in it. Thanks Mark
