Re: [SR-Users] rtpengine transcoding benchmarks?

Andreas- > We've seen around 400 concurrent calls for G711<->Opus on a rather > slow 12-core E5-2420(a)1.90GHz for some first preliminary benchmarks. Was that using narrowband (8 kHz) for Opus ? Otherwise sampling rate conversion is needed. Also I assume Opus DTX was disabled. Also at what Opus bitrate ?

Planing next Kamailio releases - v4.4.7 v5.0.6 and v5.1.2
by Daniel-Constantin Mierla 01 Mar '18

01 Mar '18

Hello, I am considering to do releases from last three stable branches during next week. v4.4.7 is going to be released out of latest code in branch 4.4 to mark the end of official maintenance for series v4.4.x. The version 4.4.0 was released in March 2016, so it had more or less two years of maintenance. Commits can still go in 4.4 branch if developers wants to push there, end of official maintenance means that there is no plan to do packaging and release another version from the branch in the future, so you will have to build it from sources or generate packages yourself. v5.0.6 and v5.1.2 are the usual minor releases we do from the last two stable branches. If there are any issues you are aware of and not reported on bug tracker, create the items as soon as possible to get a better chance to review and eventually fix.

Hello, Question about Kamailio web GUI (Siremis): I believe the Siremis updates are still a ongoing work or has there been any updates when the new Siremis update (compatible with Kamailio 5.x.x) will be released? https://www.kamailio.org/w/2017/07/siremis-ongoing-updates/ Cheers, Olli
