Anyone out there have a call center running with Asterisk? We run a small helpdesk and need some basic ICD functionality ... agent ready/not ready, call queueing, etc. There doesn't seem to be too much out there in the way of open source, so we're also looking for commercial solutions that will work with Asterisk. Any ideas? Thanks, Mike Roberts -------------- next part --------------

Hi, Sorry for the confusion. I would like to estimate a model wherein the marginals of z with respect to w1 and w2 are smooth functions of x and y. I have data on z, x, y, w1 and w2. so E[dz/dw1] = f(x,y) and E[dz/dw2] = g(x,y) and I would like to estimate f(x,y) and g(x,y) I suppose I could try to fit something more general using projection pursuit, but the nature of the problem suggests

Hello: I sent this question the other day with the wrong subject heading and couple typos, with no response. So, here I go again, having made those corrections. I would like to estimate, for lack of a better description, a partially additive non-parametric model with the following structure: z~ f(x,y):w1 + g(x,y):w2 + e In other words, I'd like to estimate the marginals with respect to

Dear R users, I am trying to find a package that can estimate an autoregressive model for discrete data. I am imagining a Poisson or Gamma process in which the mean (say mu) follows a process such as mu_t = a + b*x + c*mu_{t-1} Suppose I have data on the time-series Poisson outcomes and x and would like to obtain ML estimates for b and c. Does anyone know of a package that can do this

Hello: I would like to generate rolling, multiperiod forecasts from an estimated ARIMA model, but the function predict.Arima seems only to generate forecasts from the last observation in the data set. To implement this, I was looking for an argument like 'newdata=' in predict.lm. I can write some code that does this for my particular problem, but might there exist a

After reading the wiki, I am still confused as to whether I should install zaptel, libpri, and asterisk from cvs or use apt-get to retrieve the Debian packages. I am running Debian sarge with kernel 2.4.26. What is the prevailing opinion out there about using cvs vs. apt-get for the various components (zaptel, libpri, and Asterisk)? Thanks, Mike Roberts

Hello R users, I am doing some work with a large data set but am running out of memory. I understand that R dynamically loads memory as it needs it, but for some reason it cannot seem to find my virtual memory. It's limit is about 256M (my hard memory) regardless of the amount of virtual memory. I'm running R 1.30 on Windows NT. Am I missing an easy fix here? Many thanks in advance,

Is anyone successfully using one of these with Asterisk? I cannot get the phone to register, this message keeps coming up on the Asterisk console: Jul 29 14:11:39 NOTICE[1125350192]: chan_sip.c:7323 handle_request: Registration from '"000BEA801CA6" <sip:000BEA801CA6@hcs.net:5060>' failed for '204.194.36.138' The telephone LCD says "SIP registation

Sorry, but this may be a really dumb question. How do I load the zaptel modules wcfxo and wcfxs at boot time on my Debian Sarge system? The file zaptel.init used by the command "make config" appears to be designed for redhat type systems and does not work for me. I have tried reading the man pages for update-modules but I'm stupid and cannot figure it out. Thanks, Mike

Dear R users, I am putting together reading and resources lists for spatial statistics and spatial econometrics and am looking for some pointers from more experienced practitioners. In particular, I find two "camps" in spatial modelling, and am wondering which approach is better suitied to which situation. The first camp is along the lines of Venables and Ripley's Chapter 14

I have two problems with Asterisk and my Budgetone 100s. 1. Sometimes when outside callers dial my Budgetone it will ring twice, then the caller will receive a busy signal. This happens intermittently and I cannot pin down the circumstances of when it works and when it doesn't. Asterisk logging doesn't give me too much info when this happens: *CLI> -- Executing

Hello again, A different but related question to my last one: Does anyone know if one can easily estimate state-space models using ML and the kalman filter using R? I would be especially interested in a relatively flexible function that would allow for estimation of hyperparameters, or could be made to do so. Thanks Michael J.
