Seems a problem with FS I think . I tested same scenarios with FS 1.2 last stable and seems working fine. Problem seems more visible when transcoding iSAC into PCMU, and performing much better when you have ILBC to PCMU Silviu On Wed, Feb 22, 2017 at 2:16 PM, Caragea Silviu <silviu.cpp@gmail.com> wrote:
I removed all that sonus stuffs, and added in the bridge string : {jitterbuffer_msec=1p,rtp_jitter_buffer_during_bridge= true,sip_secure_media=true,sdp_m_per_ptime=true,hangup_after_bridge=true}
But still the same: in leg A I see a jitter of max 2 ms and avg of 1 and on leg B 26 ms max and avg of 16.

Also you probably don't need all those RTP bug behaviors, that combo is for a severe Sonus infection.

Hello,
Thanks for feedback, I removed all of them and seems the same. So might be related to the way I set the jitter buffer..
Hope Brian can clarify if I understood correctly that I should do:
1. <action application="set" data="rtp_jitter_buffer_during _bridge=true"/> 2. And in bridge string add : {jitterbuffer_msec=1p}

every one of those set lines resets that variable so only the last one is doing anything. you can set those with | seperator

Hello Brian,
Thanks for your feedback. I don't think I have something to rewrite timestamps. I also use the following (hope none of is rewriting timestamps):
<action application="set" data="rtp_manual_rtp_bugs=sonu s_send_invalid_timestamp_2833"/> <action application="set" data="rtp_manual_rtp_bugs=send _linear_timestamps"/> <action application="set" data="rtp_manual_rtp_bugs=star t_seq_at_zero"/> <action application="set" data="rtp_manual_rtp_bugs=neve r_send_marker"/> <action application="set" data="rtp_manual_rtp_bugs=igno re_dtmf_duration"/> <action application="set" data="rtp_manual_rtp_bugs=acce pt_any_packets"/>
Regarding your advices:
1. Don't use the nolocal export method, set those variables in side the {} on the bridge line. 2. set jitterbuffer_msec=1p
I'm not sure is clear enough for me. Can you please past here how looks this settings in the bridge line ? or where I can find an example in documentation ?
What I understand now is that I need to :
1. <action application="set" data="rtp_jitter_buffer_during _bridge=true"/> 2. And in bridge string add : {jitterbuffer_msec=1p}
Btw what means 1p ?

Are you rewriting timestamps or something too?

Hello,
I'm using last FS 1.6.15 to bridge a call and to transcode it as well from ILBC/ISAC to PCMU. To enable jitter buffer during bridge I'm using:
<action application="set" data="rtp_jitter_buffer_during _bridge=true"/> <action application="export" data="nolocal:jitterbuffer_mse c=60:200:20"/>
What I observed is that looking with wireshark still shows jitter on leg B which is sent to PSTN even if there is no jitter on leg A, or shows worst jitter on leg B in case I have jitter on call A.
I was expected that the jitter buffer will fix this and even if I have a slightly low jitter on leg A will not be propagated on le B as well.
I'm missing something ?
