Releasing Kamailio v5.3.1
by Daniel-Constantin Mierla 14 Nov '19

14 Nov '19

Hello, the plan right now is to release v5.3.1 during the next Kamailio Developers Meeting, if we succeed to coordinate on site, therefore expect it to happen next week during Nov 14-15. Besides just doing this specific release, to goal is to try to build a more automatic process for releases, document how is done, etc... updates about the results will follow after the event. Anyhow, for now the usual the pre-release notice: if anyone is aware of some issue that is not yet reported, do it asap in order to give it a chance to be analyzed and fixed. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference - April 27-29, 2020, in Berlin -- www.kamailioworld.com

[kamailio/kamailio] RFE: RHEL 8 builds in openSUSE build service with app_python3 (#1949)
by space88man 13 Nov '19

13 Nov '19

Consider this as a placeholder for requesting RHEL 8 / CentOS 8(TBS) builds in OBS. RHEL 8 now ships with Python 3.6 so `app_python3` can be included the the RPMs. Thank you. -- You are receiving this because you are subscribed to this thread.

So I assume that either the nat_uac_test and/or the has_body and/or the fix_nated_sdp method gets confused with the excessive whitespace characters in the Content-Length header. The excessive whitespace is probably not caused by the Bria SIP client, but by a home router ZTE ZXHN H298A. According to RFC 3261, section 7.3.1, more than one space after the colon is allowed, but not recommended. So kamailio should be able to handle it. The following workaround solves the issue: ``` if(search("Content-Length: ")) { xlog("Removing whitespace from Content-Length header\n"); subst('/^Content-Length:\s*(\d*)/Content-Length: \1/i'); } ``` -- You are receiving this because you are subscribed to this thread.
