X-Lite Build 1059 problems
Does anyone have X-Lite build 1059 working fully with Asterisk?
The GSM Codec works very well now but we have problems when using G711
in that when I setup a ping between the two sites and then watch the
latency, it steadily increases and starts at about 150ms and goes up to
2500ms within about 20 seconds. I have not investigated fully but I
guess that its sending ever increasing size packets. When we use the GSM
codec its fine. When we have used the G711 codec in previous releases of
X-Lite, it's been fine.
Also we get one way speech in the followi...

VoIP bad voice quality
...quality voice.
The problem is that voice over calls routed through SimpleTelecom
and nNufone occassionally breaks. We also have a digium card and the
calls over the digium card using the Zaptel Interface have a very good
quality.
We have enough bandwidth, the latency to the servers is 100-150ms
and the packet loss is around 1%. We tried using the G711 and G729
codec and also have the jitterbuffer enabled.
How can I solve this problem of voice quality? Can a better
implementation of jitterbuffer with packet loss concealment help? If
so how do I get the newer implementation. I would rea...

problem with echo cancellation
...n speech for far-end input
and same speech with attenuation, a bit of reverb and 50-150 ms delay, all this
done in sound editor, for mic input, i get 5-8 db attenuation.
But when i use the same speech played and recorded for mic input, i see about 5
db of attenuation only if i remove the delay (150ms) at the beginning of mic
input file to make far-end and mic input files to go almost ?in sync?, and even
in this case there?s almost no attenuation during about a second after pauses in
speech. Looks like the filter re-adapts after each pause. When the delay is at

help with "too many clients awaiting authentication"
...r digging, delete logs and restart icecast we found this:
[2020-11-15 22:09:38] INFO auth/queue_auth_client auth on (default mount) has 101 pending
[2020-11-15 22:09:38] WARN auth/auth_add_listener too many clients awaiting authentication
Before those errors our auth api was logging ~60 rps in ~150ms (during the error the api was not getting requests).
Has anyone else has already faced this problem? Any tips?
Best,
Thiago

PRIO not working?
...TC -s qdisc show dev ${IFACE}, I see, that the packets go to
correct qdiscs.
But when I start FTP data transfer, then the ping time is same with and
without this shaping.
I should also mention, that I am testing it on WiFi with hostap drivers,
where the ping times are about 2-3ms when idle and 100-150ms durring high
traffic.
Is the first/fastest prio class really 1:1, and the last/slowest is 1:4?
Or did I miss something else?
A part of the code follows:

g729 and latency measures
...kilobytes??) for the internet
bandwith.
i cannot use CRTP because i cant be sure if the ISP's routers are CRTP aware.
Installing ADSL from ISP1 on the asterisk place will give a clear advantage
Please correct any of my prior statements if wrong.
should I maintain packet latency below 300ms or 150ms?
How can I measure this latency all the way to the asterisk? Should I
ping from SITE_A to the asterisk box with 8k packets?
If I can't install ADSL for the moment, will the above setup work?
thanks in advance for all your help.
Erick.

Ferret slow after a while
I''m building a new index from scratch based on a number of documents
stored in a database loaded using my Rails env (using Ruby Ferret 0.9x
(installed today with Gem) on Windows). At first everything goes nice
but after a number of documents it starts to go slower and slower until
it grinds to a halt (at least feels like it).
Am I doing something wrong? Is there some way to work

epoll increasing latency big time
...EventMachine to proxy HTTP to other processes.
On OS X, it works great, adding only about 20% extra latency into the
connection when proxying versus connecting to the original backend process
directly, so a 5ms connection might now take 6ms. On a Linux deployment,
however, that 5ms was going up to 150ms! I noticed that when I removed
EventMachine.epoll, everything corrected itself and it worked as quickly as
in OS X. So, for now I''ve removed EventMachine.epoll, and all is well.
The first question, therefore, is does anyone have any experience or
knowledge of why using epoll could make an...

Clamping tcp mss values to decrease latency
Hello,
I have an interesting question. I can''t find a solution anywhere to this
problem.
I have an adsl connection which is able to send a full data packet in
about 150ms. I want to cut this time down to decrease latency while
serving files, so I thought I''d try and reduce the packet size for the
offending upload streams (my webserver). The trick is that I also want all
other tcp connections to have the normal full packet size. Enter
MSS-clamping. My pppoe...

ov_open_callbacks takes so much time to open 210 MB OGG file
Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so

The OGG file has just 210 MB. It takes a lot of time open the file.
I am working on OGG audio recorder and player.

Shout.delay
...An observation is that icecast buffers seem to keep
growing -- information from liquidsoap is more and more in advance
compared to what one hears. So I decided to ask delay() if
liquidsoap's centralized scheduling is correct for shout outputs. It
appears that delay() is nearly a constant, about 150ms. I'm wondering
about the precise meaning of this.
First interpretation: icecast is warning us that the buffer is growing
too fast, something is wrong, liquidsoap shouldn't be so fast. Second
interpretation: everything's ok, the advance is a constant so it has
no impact on the buffer. I...

[Bug 583] Chokes
...describe what happended, but I'll try.
After changing from 3.5p1 to 3.6.1p2 without any changes in compilation, or
configuration, sshd started to "choke". Data displayed on the terminal is
displayed partially for example half of the screen in 200ms and the rest after a
pause of 100-150ms. It's realy annoying. I have 100mbit/s full-duplex cards.
Load average is about 0.02. Everything was fine, till i've changed the version.

Analog commands
Hi,
When I use the analog phone connected to Zap/1 how do I transfer & hold the
caller ?
When I hit the flash key, all that happens is the caller hears a beep
(sounds like DTMF).
But no stutter dial tone on the Zap/1 Port, just continuing conversation
with the caller.
What could be wrong here?
Cheers
Jay
