Voice Activation Level (speex 1.1.11.1)
Sorry.
I forgotten the words volume or loudness.
But it is know as microphone stroke too, i think.
If something can tell me something about that
procedure it would complete my pleasure.
To bring back memories,
i only wanted to know wheather i can change a
variable that holds the sound intensity (loudness)

Encoding mode
Hello,
In the internet draft describing the SDP parameters for speex
I find this:
mode: Speex encoding mode. Can be {1,2,3,4,5,6,any}
defaults to 3 in narrowband, 6 in wide and ultra-wide.
In the documentation I can only find the following request:
SPEEX_SET_MODE
There is no description though what this request does.
I think the mode somehow maps to the bitrate, but I

LoadBalancing on many asimetric different dsl''s.
Hi,
my company have just bought new network and I have question about one problem.
As in topic we must use few completely different dsl''s and balance traffic between them.
2M/0,5M 4Mb/0,5M 8M/0,5M
M=Mb/s
I''ve never done such thing before so I have doubts how it will work. If the links are symmetric 2/2 4/4 8/8 there is no problem because with weights I can compensate the

Voice Activation Level (speex 1.1.11.1)
I havent had found anything in the documentation about voice activation levels.
Does i can change a variable to change the accuracy for activations?
If not does the speex lib already implement a function for read out the
sound level of a frame?
Thanks for the advance.

How does the jitter buffer "catch up"?
> FYI: The below is just my interpretation of the code, I might be wrong.
Most of it is right. Actually, would you mind if I use part of your
email for documenting the jitter buffer in the manual?

transferring calls from ekiga to asterisk
I have ekiga registering to a voip provider (skypho) and receiving
external call
through the stun server.
I want to redirect inconditionally all these calls to my asterisk
server, but I can't understand how and what should I configure in
asterisk in order to accept the redirected call.
In asterisk console I can't see nothing when ekiga passes the call.

G.722 problems with IAX
Hello,
I try to move our asterisk installation (3 Asterisk servers in different
offices connected using IAX and a lot of SIP phones, as well as ISDN
connections using CAPI) to use G.722 instead of G.711.
Asterisk 1.4.25.1 is used with the G.722 patch (the fixed one, which solves
the gain problem).
So SIP-to-SIP and to ISDN there is no problem. G.722 itself works and

Protecting against kernel NULL-pointer derefs
All,
Given the amount of NULL-pointer dereference vulnerabilities in the
FreeBSD kernel that have been discovered of late, I've started looking
at a way to generically protect against the code execution possibilities
of such bugs.
By disallowing userland to map pages at address 0x0 (and a bit beyond),
it is possible to make such NULL-pointer deref bugs mere DoS'es instead
of code

summary statistics for lists of matrices or dataframes
Is there a simple way to calculate summary statistics for all the

trivial list question
Dear experts,
For the makeGenotype function I need a list as in the example. However,
since my list needs to be 184 long there must be an easy way to make it.
>list(1:2,3:4,5:6,7:8)
[[1]]
[1] 1 2
[[2]]
[1] 3 4
[[3]]
[1] 5 6
[[4]]
[1] 7 8
I have tried
lis<-1:184
dim(lis)=c(92,2,1)
as.list(lis)
and several other options. Any suggestions?
many thanks

lapply and list attributes
Hi
I have a list that has attributes:
attributes(lis[2])
$names
[1] "150096_at"
I want to use those attributes in a function and then use lapply to
apply that function to every element of the list, eg for simplicity's
sake:
my.fun <- function(x) {
attributes(x)
}
Then
l2 <- lapply(lis, my.fun)
It seems that "attributes(x)" within the function is not the

Liveness Analysis
So what is the status about LiveVariables. Is there a plan to remove it?
After searching in old lvm-dev-mails it is mentioned that LiveVariable
still exists due to one pass needing it. And a comment in
TargetPassConfig.cpp indicates that the pass in question is
TwoAddressInstruction:
// FIXME: Once TwoAddressInstruction pass no longer uses kill flags,
// LiveVariables can be removed

printing name of object inside lapply
Dear list members,
I am trying, within a lapply command, to print the name of the objects
in list or data frame. This is so that I can use odfWeave to print out a
report with a section for each object, including the object names.
I tried e.g.
a=b=c=1:5
lis=data.frame(a,b,c)
lapply(
lis, function (z) {
obj.nam <- deparse(substitute(z))
cat("some other text",obj.nam,"and so
