A thought occurred to me to on how to further quantify the impact of "glare" on a properly dimensioned trunk group and debunk the ground start glare concern. A cursory traffic analysis clarifies: 1. Assume you have a two-way trunk group, dimensioned for average busy hour, average busy season for P01 grade of service, Erlang B or Poison distribution. 2. Further assume that the

Hello! As the subject states, I'm experiencing an odd issue with one of my client's systems. We're running a Sangoma A400D card with 8 FXO channels. The POTS line on channel 5, whenever called, generates the following message on the asterisk console: Apr 29 10:35:08 WARNING[16927]: chan_zap.c:3926 zt_handle_event: Ring/Off-hook in strange state 6 on channel 5 Apr 29 10:35:09

hello, I just installed 2 brand new x100p cards into my linux system. Everything compliled and worked fine from the first try. Hoewver the phone lines I will use with this system have groundstart signaling. I have tried to change the zaptel.conf and zapata.conf to use this type of signaling but ztcfg gives me an error every time with the new configuration. Bellow are the config files and the

Hello, I am having problems configuring a TDM400P 4 Port FXO card with groundstart signalling. The box has 2 X100P's, 1 TDM04B and 1 TDM40B. I can configure it for loopstart and it works, just not groundstart, which I need for this installation. What am I missing? Thanks!

Hello! I've run into a problem where a user is making an outbound call at the same time that an inbound call is being made on the same analog line. It appears that as the zap channel is opened for the outbound call, it is simply answering the inbound call. Obviously, both parties involved in the calling get a bit confused. Previously, it happened only on an occasional basis. However, as this

Callerid issue 1) if you run ztmonitor on the fxo line & call in do you hear the fsk tone if yes then we beleive the CAC is passing fsk 2) in chan_zap->ss_thread around line 4154 (current cvs) if you get to the callerid_feed at least once then if you get to chan_zap->ss_thread->callerid_get around line 4163 (current cvs) does this parse fail

Hello Astrites, I was just about to send out a long email about not being able to detect hang-up with my CAC II FXO module on my PSTN POTS lines. I had tried many configurations. I had attached a toner to the line to see if I was getting this "disconnect supervision" signal after hang-up. (toner has a line powered light in the off position) It seemed that I was getting the signal,

I am having a problem using the Adtran 750 FXO quad card with a Groundstart trunk line. I am able to receive calls on the trunk line, however dialing out is not working. The Adtran does not seem to be doing the signaling. Has anyone used the 750 FXO card in Groundstart mode? Any special configuration issues that I should be aware of?

Why pay 1.1 cent's a minute for interconnecting to another Asterisk server for a high volume call center. Do people really understand what they are trying to sale and take an honest look into what they advertise. As a high volume user like a call center I would not connect my Asterisk Box to there Asterisk Box to a third Sip provider who then hands of to the Level 3 and so forth. With LD

Greetings list- I'd like the ability to hangup all calls for a particular extension from the system CLI. I understand this can probably be scripted using the AMI but I'm not familiar on how to do it. Help! Tim Nelson Systems/Network Support Rockbochs Inc. (218)727-4332 x105

Greetings list! Because of the sheer number of box (re)installations we do that have a CentOS base, I've converted our provisioning process to PXE. However, I've found that an alarming number of motherboards are coming with the Realtek RTL8168 ethernet controller onboard. When the system boots, it cannot find an ethernet controller and the installer process hangs. I made a new initrd

Hello! I'm having a bit of an issue with one of my installations that I cannot figure out. For some reason, when two people are in a call (both local to the * box, same subnet, pure SIP), the call will randomly be placed on hold and provide MOH to the other party. We're using Polycom IP430 handsets almost exclusively for this installation. Can anyone think of a reason why a call would

Hello list- I'm having an extremely odd issue with an installation of mine. The system is running * 1.2.12.1 and currently handles around 100 handsets. With the exception of a few Grandstream DTA's, all devices are Polycom 320, 430, or 601's. After a recent power outage, I'm having an extremely odd issue with one of the handsets. One of the Polycom 601 units simply reboots every

Greetings all- I have a system running CentOS 5.5 x86_64. It's serving NFS for several 'frontend' boxes in a web application setup. All data is stored in specific dir but written by different users. When the webapp attempts to read this information, it may or may not have permissions to this data. What I'd like to do is set 'default permissions' on the data storage

Hi, I have a TrixBox install with a Sangoma A200 and 4 FXO ports, there are 3 BT lines connected directly to these ports. One of the lines has BT FeatureLine Compact and this is the line I am having problems with, the other 2 lines are working perfectly, detecting CID, answering incoming calls and placing external calls via SIP devices. I am receiving a error log entry: chan_zap.c:

It is widely known that Quickbooks has a horrible storage engine, "requires" Windows to host multiuser access, etc. However, I've successfully been storing QuickBooks files on Samba shares at a handful of locations with no real issues other than slight performance degradation. However, a somewhat recent thread here mentioned the proper use of oplock'ing in the Samba configuration

Now that's quite interesting - yes, this is a two way span. I thought that the D-channel negotiation that happens before the B-channel is set up would have implicitly avoid the glare condition through signalling the intent-to-use to the resource to the remote end (a-la E&M wink start). So what seems to be happening in my case is my CPE is set for a 'Descending' b channel sequence

I am having a problem with Red Alarms on X100P cards. The most frustrating thing is I can not duplicate the alarms, therefore am not sure how to solve it. I have read after searching posts and the web that you can try different signaling methods which may help alleviate the problem. There is fxsks (Which I am currently using), fxsgs, and fxsls While reading the Digium site about these different

Hi list, I'm now considering to buy a new server for an Asterisk installation, since I've been kindly advised<http://lists.digium.com/pipermail/asterisk-users/2007-October/198146.html>not to use an old server for a mission critical app...
