OK, doing <action application="export" data="nolocal:absolute_codec_string=PCMA,PCMU"/> <action application="bridge" data="sofia/gateway/FreeSWITCH/201"/> Seems to take care of the transcoding. I'm going to try and move this back to one server. Erik On Mon, Jan 29, 2018 at 1:14 PM, Erik M. Devane - Comms Guy < emdevane@gmail.com> wrote:
I've worked on this some more, and have been able to watch a little more of what's happening by splitting into two FreeSWITCH instances and sending traffic between them.
I can make the jitter buffer and delay_echo provide the required delay, and this works fine with a basic SIP softphone.
What's happening is that mod_portaudio is providing L16 at high sample rates and isn't transcoding it even across servers.
It seems that I need to convert L16 48K to (say) PCMA or OPUS or something that delay_echo or the jitterbuffer could deal with.
Is that something that's possible? I know I can eavesdrop or send to a conference, but is there a way I can easily convert from portaudio to something more generic to send to the dialplan?

here you need to choose Alice or Bob will have JB, not both of them only half

I'm sorry, I'm just not having any luck getting this going.
Ideally, I'd like to be able to originate the portaudio endpoint into park, and eavesdrop on it there, but I understand that's convoluted to work with, so as a test I have a single extension:
<extension name="portaudio_USB"> <condition field="destination_number" expression="^1(\d{2})$"> <action application="answer"/> <action application="set" data="rtp_jitter_buffer_during_bridge=true"/> <action application="export" data="nolocal:jitterbuffer_mse c=3000:3200:20"/> <action application="bridge" data="portaudio/endpoints/USB_01"/> </condition> </extension>
Dialing 101 from a SIP client (MicroSIP) as user 1000 from the default configuration causes me to be bridged to the portaudio endpoint (I can hear input from the channel), but there's no delay at all.

also you'll have to set rtp_jitter_buffer_during_bridge to true.

Then you should try to set JB for b-leg via export nolocal.

Thank you for the reply. Here's what I tried:
<action application="set" data="jitterbuffer_msec=3000:3200:20"/>
Works for calls from SIP clients but not for PortAudio calls.
Same with delay_echo - the CODEC is seen as RAW and so the jitterbuffer doesn't seem to be engaged (read_frame->packet doesn't have anything to work with so it skips the buffer).
I have tried to have PortAudio > extension 1 > bridge to extension 2, which produces better results, but (in my hands at least) it causes memory leaks and is unwieldy.
