Subject: Re: [Freeswitch-users] *.tmp.xml.fsxml Files

we never make files with that pattern, we will make files with .fsxml.tmp there in some cases.  What are the exact filenames?

Hi All,

Can anyone confirm what the purpose of these files are in FreeSWITCH's log directory?

They're all empty so no clues in the actual files.

libc@20 is a totally valid rate for libc.  If they are rejecting that, you should file a bug with them.  Depending on how you are negotiating codecs you could force it by our normal codec negotiation settings.

Subject: Re: [Freeswitch-users] ​*.tmp.xml.fsxml Files

are you sure thats the file pattern?  we do put uuid.tmp.xml files in there in some cases.. but not uuid.tmp.xml.fsxml.

Hi Josh,

Hope your keeping well mate.

I know about that one :)

These ones are suffixed ".tmp.xml.fsxml" with what looks like a UUID as there filename.

But they're all empty....just wondered if anyone else knows what they're for.

Thanks,

Luke

Subject: Re: [Freeswitch-users] FreeSwitch & Simulcast

Currently there are lots of good tools to do SFU, I’m not sure what the upside is to us doing SFU as well that is not already covered by other tools.  Its a similar discussion to people who want FS to be a proxy.  If there is sufficient demand and funding to do the work, we would consider it.  Lacking the funding to do this work I don’t see the drive to do it.

Hi,

I'm wondering where do FS stands now and what is the plan for future?

I saw there were PlanB and Unified Plan but I guess none passed the point of proposal I guess.

Now I see some different "webrtc standards" as rid in sdp. 

Simulcast is the future I guess, like it or not i guess.

My general question is will FS go in SFU direction and why not  ??? :D
