Meaning of packet loss log message
by Thomas Auge 19 Aug '17

19 Aug '17

Hello list, I'm seeing log entries such as this: switch_core_media.c:2509 [VBR]: Correcting calculated ptime value from [40] to [20] to compensate for [1] lost packet(s) They are often accompanied by very audible clicks without any PLC. RTCP does not appear to report related packet loss according to Chrome's webRTC stats. This is between SIP and portaudio. Does anyone know at which stage that packet loss occurs, or what could be causing it? Thanks, Thomas

Re: [Freeswitch-users] Separate CA authorities for SIP TLS
by Robert Mundkowsky 17 Aug '17

17 Aug '17

Usually different systems can use any authorities, but the usually have to have the the complete chain to the root installed in their key stores. So system Y has to know it can trust certs from CA X. So question is do you know where the key stores are located for each system and how to add certs to them. -------- Original message -------- From: Maciej Bylica <mbgatherer(a)gmail.com> Date: 8/17/17 11:37 AM (GMT-05:00) To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Subject: [Freeswitch-users] Separate CA authorities for SIP TLS Hello, I am about to setup TLS SIP interconnect between Cisco servers (C3945) and Freeswitch.CA server for Cisco devices is already in place (located on different cisco server).I want to proceed with CA Root certificate generation on Freeswitch server as well.My question is if i could use different CA authorities (separate for Cisco devices and the one for FS) for SIP TLS calls coming back and forth between Cisco and FS?

Channel variables on a-leg and b-leg
by Paul Mateer 17 Aug '17

17 Aug '17

Guys, I'm using the C# interface to FreeSWITCH to add the ability to make and receive calls in an existing software application. I want to record the conversations on the server, but I need to be able to access the recording after the call is complete. The Call-ID value seemed the perfect solution to this and I added the following action to my dialplan entry. <action application="export" data="execute_on_answer=record_session $${base_dir}/recordings/${strftime(%Y.%m.%d_%H.%M.%S)}_${uuid}_${caller_id_number}.wav"/> This seemed to work fine, as I would get recording files created with a Guid in the name, but on closer inspection I found that the Guid used in the filename was not the same Guid associated with the successfully placed call in the application. I assume that this is because the application sees the Call-ID for the a-leg, whereas the dialplan entry is executed in the b-leg and therefore has it's own separate Guid. Is there any way in which I can expose the Call-ID (or some other custom channel variable) for the a-leg to the b-leg so that it will be accessible within the XML dialplan and therefore be usable when creating the recording file? Thanks for any suggestions/assistance offered.
