How to set the jitter buffer
Hi!
I just wondered if anyone would mine posting their successful jitter
buffer settings here for me if they get a moment ??
I've spent a few hours trying to set the jitter buffer up reasonably
logically and can definitely tell it makes a difference and can introduce
latency and echo if setup incorrectly but I can't see a good post anywhere
describing properly what the three settings

voice over atlantic
Hi-
I'm using IAX between two boxes, where one box is located in US and the
second in Europe. I'm trying to achieve the best voice quality and
mainly reliability between these boxes and looking for hints and
experience of others.
Facts:
- Asterisk 1.0.7
- RTT varies from 130-170 ms, depends on time and actual Internet
throughput
Questions:
- What is the sugested codec for such setup?

IAX2 goes "one way audio" when lag gets bad
Hi,
I have a customer who experiences, once in a while, one-way audio...
That is... they can hear the person they called, but the person can
not hear them.
The customer is connected via IAX2 to our softswitch.
On the customer's end I have the following config in iax.conf:
[general]
bindport = 4569 ; Port to bind to (IAX is 4569)
bindaddr = 0.0.0.0 ; Address to bind to (all

Asterisk 1.2.4 IAX2 New Jitterbuffer Tuning
I was using G729 with Asterisk 1.07. With the new ability to do packet
loss correction with ILBC, I felt I'd give it a try. The new PLC does
not work with G729. I don't use Speex because my softphone does not
support it.
This is a 1.5mb IP-VPN connection with prioritized QOS for port 4569
(IAX2). I've never really stressed the bandwidth. Typically, only
10-20 concurrent calls.

DTMF over IAX
Ok sorry for not being specific. I am having a problem when people
outside call in to my number which terminates at VoicePluse then The
send IAX to me and I do not get any tones. People press buttons but it
just goes to the next dialplan fall through. It happens 60-70% of the time.

jitterbuffers - suggested settings
Hi,
I was wondering if anyone else has a similar setup and can suggest
settings for the jitterbuffer:
I have a client with an ADSL connection at site A & B with site A being
dedicated to voice and having no Asterisk server, site B combining
voice and data with traffic shaping and housing an Asterisk server.
There seems to be packet loss / jitter on this connection and I wanted
to know

IAX Calls - One Way Audio
Hello List,
I am currently having a bit of a strange issue with a pair of asterisk servers that we recently set up.
For a bit of background, this particular business has two sites in two different towns, about 10 minutes apart. They have 3 analogue PSTN lines connected to the asterisk servers at each location, via a Sangoma A200 (with HEC). They are trying to have just the one receptionist for

SIP to IAX - forcing codec pass thru
hi
We take calls inbound via SIP from our Cisco PSTN gateways, and pass it
to customers using IAX (they run their own asterisk servers).
We've noticed that asterisk is transcoding the call into a different
codec, if the customer prefers a codec different to that which our cisco
gw prefers. As such, the quality of the call can degrade.
We'd rather asterisk just passed through the RTP

Two Connected Servers Sound Quailty
Ok this is my first post and I will try to keep it short.
I have searched everywhere and haven't found an answer to my question
I have two Trixbox servers that are connected over the Internet via an IAX2
connection. We are experiencing very poor sound quality. I have tried many
different codecs gsm, ilbc, g729, g711 and all seem to have the same
problem. (All though g729 seems to work the

How can I improve call quality?
Hi All,
I've a single 1.2.17 Asterisk system. Gradwell here in the UK is used
for PSTN calls via IAX2.
Our 'net link is a dedicated 2Mb fibre connection (of which we have ever
used 50% max bandwidth). We've no E1/T1 links, everything is IP based.
My boss complains that many of the calls he holds with others has a bad
quality. He also says that its not just him.

Problems with the Speex Jitter Buffer
Hi,
I am using the JitterBuffer. Since there is not so much documentation I
think I dont use it in a correct way. All the packets are recieved (I
control the sequence numbers) but the JitterBuffer often tells me he has
no packet. I am using it in the following way:
I am not sure if I use the ticks correctly but I think it can be set to
20(msec).
It is set as a Member in my class and i

Problems with the Speex Jitter Buffer
Thanks for your reply Jean-Marc!
this was what I had before.
But I decided to restructure it since the thread that plays the sound is
a callback from the sound hardware, more or less an interrupt handler.
For me it seems more reasonable to waste some memory for to save the
decompressed Packet. While I write this I begin to think that it is
possible I decompress Packets that are never used

Jitter buffer question
Hi List,
I have a question regarding jitterbuffer in Asterisk 1.4.24. I see that
jitterbuffer is only effective on the receiving channels.
My asterisk has only SIP accounts + 2 SIP trunk accounts to our branch
office.
Questions:
1. To enable jitter buffer on SIP channels it seems I have to enable and
force it, right?
2. If I enable and force jitter buffer, Asterisk would always have to
stay

call quality monitoring
I need to debug a call quality issue with remote users on the other
end of a satellite link. The symptoms are: we here on the Internet
side can hear them just fine. On their end, things work sorta OK most
times, but they often suffer from severe dropouts and digital
warbling, both of which I attribute to them missing packets. Often
times they can't make out a word we are saying while we can

Disposition codes in CDR
Is there any way to have more specific disposition codes in the CDR?
Currently there are only 3 values: ANSWER, NO ANSWER, BUSY.
In this way, when i call a cell phone that is switched off i get "NO
ANSWER", while i would like to be able to log that the call is not
answered because "The customer you have dialed is unavailable at the
moment".

IAX2 REACHABLE/UNREACHABLE
All,
I have an issue with IAX that I can't comprehend. Approximately every eight
minutes my servers go unreachable. They stay unreachable for exactly 10ms.
I have two servers running IAX and it happens on both servers
simultaneously. I have searched the archives and see similar issues, but
not the exact same one. I am on the current CVS stable version of *.
Also, during IAX calls,
