Calls to voicemail drops after 41 seconds due to no rtp packets
Hello,
I have my provider dropping the calls after 41 seconds of not receiving any
RTP from my asterisk. Obviously there is no RTP back when the caller is
leaving a message in the voicemail. Is it possible to have asterisk
generate some RTP packet back?

Is there a way to make asterisk send a INVITE in-dialog to re-establish the audio
We are working with an Avaya switch.
We send them a REFER. If the transfer is successful, everything is great. If it fails (busy), they send an INVITE in-dialog with a media attribute of inactive. After that, they send a 486 busy.
The problem is Avaya basically put the call on hold so audio is not active.
The Avaya rep is indicating we need to send in dialog invite to get the call audio back?

[LLVMdev] [PATCH] Parallelized make check
Hello,
The attached patch adds the jcheck target equivalent to make check, but
that can run with a -j flag ($ make jcheck -jX).
It does not interfere with the regular check, but rather builds on top
of the check-one target: it first generates a list of tests to run using
RunLLVMTests, and then run those tests according to the supplied -j
flag, invoking the check-one target for each one of them.

how to recode in my dataset?
Dear Rusers,
My question is about "recode variables". First, i'd like to say
something about the idea of recoding:
My dataset have three variables:type,soiltem and airtem,which means
grass type, soil temperature and air temperature. As we all known, the
change of air temperature is greater than soil temperature,so the
values in those two different temperaturemay represent different

How to recode variables using base R
Hi,
Is there an efficient way recoding variables in a data.frame using
base R? My purpose is to create
new variables and attach them into old data.frame. The basic idea is
shown below, but how to create recoding for A, B and C and assing them
into new variables?
df <- data.frame(A = c(1:5),
B = c(3,6,2,8,10),
C = c(0,15,5,9,12))
df$A[df$A <= 3] <- "x"
df$A[df$A > 3 &

manipulating multiply imputed data sets
Hi folks,
I have five imputed data sets and would like to apply the same
recoding routines to each. I could do this sort of thing pretty
easily in Stata using MIM, but I've decided to go cold turkey on other
stats packages as a incentive for learning more about R. Most of the
recoding is for nominal variables, like race, religion, urbanicity,
and the like. So, for example, to recode race

Recoding scores of negatively worded item
Hi,
I'm new to R so please fogive if I write someting silly ...
I need to recode a series of responses from a number of questionnaires.
The data is read via ODBC from a database where all responses are coded
as tables of the form (id, question, score).
After dealing with recoding of missing values, I need to "invert" the

SAS-like method of recoding variables?
Dear R-helpers,
I am helping a SAS user run some analyses in R that she cannot do in
SAS and she is complaining about R's peculiar (to her!) way of
recoding variables. In particular, she is wondering if there is an R
package that allows this kind of SAS recoding:
IF TYPE='TRUCK' and count=12 THEN VEHICLES=TRUCK+((CAR+BIKE)/2.2);
Thanks for any help or suggestions you might be able

Seeking help with an apparently simple recoding problem
Hello,
I have struggled, for longer than I care to admit, with this seemingly simple problem, but I cannot find a solution other than the use of long drawn out ifelse statements. I know there has to be a better way. Here is stripped down version of the situation:
I start with:
a <- c(1,0,1,0,0,0,0)
b <- c(1,1,1,1,0,0,0)
c <- c(1,1,0,1,0,0,0)
rbind(a,b,c)

Conditional recoding
I am trying to recode a variable into another variable and while the package
'car' works well when it is only recoding A into B, I am not sure I can do
the same with recoding (A or C) into B. If i can use recode please advise on
how to. So i am using an if/else if conditions.
My sample dataset is below along with the code and the warning and results i
get.

A problem with recoding agents calls via monitor

Automatic Recoding
I have a text file full of numbers (it's a edgelist for a graph) and I would like to recode the numbers as they are way too big to work with. So for instance the following:
676529098667 1000198767829
676529098667 100867672856227
676529098667 91098726278
676529098667 98928373
1092837363526 716172829
would become:
0 1
0 2
0 3
0 4

i.e. all 676529098667 would become

recode vector values to NA
Greetings,
I'm in the painful process of migrating from SAS to R. In the process I've
discovered that there are some basic things that I am getting hung up on. The
most basic is the simple recoding of variables. Suppose I create a vector
x <- rnorm(10000)
and I want to recode all values of x > 1.5 to NA. How would I do that in R?
TIA

Recode of text variables
Hi all
I am trying to do a simple recode which I am stumbling on. I figure
there must be any easy way but haven't come across it.
Given data of A","B","C","D","E","A" it would be nice to recode this
into say three categories ie A and B becomes "Treat1", C becomes "Treat
2" and E becomes "Treat 3".

regrouping factor levels
Hi all,
I had some trouble in?regrouping factor levels for a variable. After some experiments, I have figured out how I can recode to modify the factor levels. I would now like some help to understand why some methods work and others don't.
Here's my code :

numeric variables converted to character when recoding missing values
Dear R helpers,
I have a data frame where missing values for numeric variables are coded as
999. I want to recode those as NAs. The following only partially succeeds
because numeric variables are converted to character in the process:
df <- data.frame(a=c(999,1,999,2), b=LETTERS[1:4])
is.na(df[2,1]) <- TRUE
df
a b
1 999 A
2 NA B
3 999 C
4 2 D
is.numeric(df$a)

recode categorial vars into binary data
Dear R-List,
I would like to recode categorial variables into binary data, so that all values above median are coded 1 and all values below 0, separating each var into two equally large groups (e.g. good performers = 0 vs. bad performers =1).
I have not succeeded so far in finding a nice solution to do that in R. I thought there might be a better way than ordering each column and recoding the
