Using Local in queues a good idea? (or at least not a very bad idea?)
Hi, I'm now thinking of always dialing out to Local/xxx at outbound/n on all my queue members. The reason for this, is both to be able to limit the number of calls to one agent, and to have fail-over-lines on the agents. (for example, if dahdi fails, go sip) But for a few years ago, I did some testing with Local/ channels, and they seemed somewhat unstable in large quantity. Are they more

app_queue problem with Ringing state
Hi, This is the output from queue show 28: 47 (DAHDI/g0/12345678) (realtime) (Ringing) has taken no calls yet Why is the devicestate "Ringing" when no channels is calling this number, and the queue says "has taken no calls yet"? Is it picking up the general state of a random channel on g0 in dahdi? Or what is happening? It only seems to happen with this particular

MATH
I want to create a script for IVR that compiles responses, aggregates them to a total number. Then, run an equation based on the result. Press 1 for X (X is a positive number 500) Press 2 for Y (Y is a positive number 200) Press 3 for Z (Z is a positive number 300) Press 20 to calculate the results = 500+200+300 =1000 then, exten => s,n,Read(NUMBER,,1000) exten => s,n,SayDigits(${NUMBER})

Getting: Can't fix up channel from 5 to 7 because 7 is already in use, and pri_dchannel: Answer requested on channel 0/7 not in use on span 1
System have been working great for weeks, using an average 40 of 120 dahdi channels. But today, I suddenly see scary things like this: -- Moving call from channel 5 to channel 7 [Feb 25 10:18:12] WARNING[17129]: chan_dahdi.c:10608 pri_fixup_principle: Can't fix up channel from 5 to 7 because 7 is already in use [Feb 25 10:18:12] WARNING[17129]: chan_dahdi.c:11535 pri_dchannel: Ringing

Early audio(progress) and MOH
Hi, Is it possible to have MOH in early audio, while waiting for someone to pick up a Dial() call?

CDR problems with Queue
Hi, I'm having problems with CDR's and Queues in Asterisk 1.6.1. Heres three examples: Normal call: User A calls in to asterisk, gets a PlayFile, and hangs up. This gives 1 CDR as expected. Call to a Queue and then a playfile afterwards: User A calls into asterisk, goes into a queue, asterisk calls user B. When user B hangs up a CDR for User A is generated. (no CDR for user B)

zaptel/pri, early audio, dial()
Hi, Is it possible to have early audio while waiting for answer in a Dial()? Say that I want to do this: 1,Progress() // Establish early audio possibillites 2,Dial(SIP/user,20,z(repeated-musicfile)) Where z would be like a function for playing early audio. Or z would just start MOH without Answer()'ing first. H?kon Nessj?en Loopback Systems AS -------------- next part

New feature: Asterisk Manager Interface commands for DeviceState
Hi, I've uploaded a new patch at https://issues.asterisk.org/view.php?id=16732which adds two new AMI commands, called "DeviceStateSet" and "DeviceStateGet". These commands let you update Custom device states, and read all devicestates from AMI. It would be very nice if someone could help me test this feature, and report back to the issue tracker. To test, log into AMI

New patch for app_queue to show all call attempts, even failing ones
Hi, I've just uploaded a patch here: https://issues.asterisk.org/view.php?id=16925 This patch introduces a new parameter; "congestion" to both RINGNOANSWER in queue_log and AgentRingNoAnswer AMI event, which is set to 1 if the call failed to go through because of technical difficulties. And it also is more verbose than app_queue has been earlier, since app_queue usually silently

[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:

Load balancing Asterisk.
Hello! We're looking for a solution to reliably load balance our Asterisk boxes. So far we've been using a hodge-podge of directing different services to different boxes/IPs, but eventually I'd like to consolidate things so we can present a single IP address to the outside world. My question is - how do we go about doing that? I've read a lot of things like load-balancing via

Newton's method for finding roots
Hey guys, i have a relatively simple problem. I need to use netwon's method to find the root of a polynomial, lets say x^3-2x-1 i start off with p <- function(x) x^3-2*x-1 My method, which im sure is very amateur, is to type another function, which is the derivative of p, and after picking an initial value to start off with, i follow the steps of newton's method manually, but i dont
