Software :: VoIP Setup With Asterisk Appliance IP04?
Nov 17, 2009
I am encountering a strange problem on my VOIP setup Basically, I have a asterisk appliance IP04. I have setup all the extensions and everything. I use a Linksys PAP2T as an ATA remotely. Now, my problem is the ATA sometimes is okay can call SIP and PSTN but sometimes I just can't hear anything. I thought it was my ISP blocking the VOIP packets but I have tried both the SIP softphone and IAX2 softphone on my PC. For IAX2, it works perfectly however in the SIP, I can hear the other end but they cannot hear me.
These are the ports I have opened on my router
1.) UDP 5060 - SIP Port
2.) UDP 10000 - 20000 - RTP Port
3.) UDP 4569 - IAX2
Do I need to open both TCP/UDP for these ports or UDP should be enough? These are the test cases:
1.) Using my WiFi Connection and a analog phone connected to ATA --> Sometimes working sometimes not and sometimes you can call SIP but the other end cannot hear you
2.) Using IAX2 in WiFi connection --> This one works perfectly
3.) Using a mobile phone connected to WiFi Network --> The same...but you can call and go out on PSTN but the other end cannot hear you
4.) Using a mobile phone connected via 3G --> Works perfectly but as expected it is quite slow and voice quality is awful
I want to use SIP rather than IAX2 because it is widely used and since my ATA doesn't support IAX2. Are there other ports I need to open or configure?
I have two asterisk servers each one behind a linux firewall/gw. Linux is Centos 5.4, kernel 2.6.18-164.el5, iptables v1.3.5. Routes on the fws are ok and when iptables is stoped the servers are see each other, all good. But when I run iptables script in any fw, one server (not always the same) goes unreachable. I verify this with asterisk -r, then show sip trunk, and status becomes UNREACHABLE.
Iptables scripts is generated by fwbuilder. The weird part is I put only one rule to de script and it looks like Source=any, Destination=any, Service=any, Interface=any, Direction (Inbound,Outbound)=any, Time=Any, Action=ACCEPT. So as you can see I tried something like "Do not do anything at all". But anyway I run the script in any fw and one server becomes UNREACHABLE. I think the script does something wrong after all or maybe I have some missconfiguration in my asterisk conf files. The point is I am not so expert in iptables or shell scripting so I can't see anything in the iptables script. I have look for some issues like iptables blocking because of ip_conntrack table full, or "dont fragment" bit set in kernel problem, but nothing seems to be the right problem at all.
I was just wondering if you know of any site/forum that is informative about Asterisk. I have just configured an Atcom IP04 in which Asterisk is embedded. I need to know how to configure the IP-PABX to receive fax and come up with a Skype Gateway to receive/call out on Skype.
Today my boss come to me and ask me to get a cote to upgrade our old "Cisco call manager" (2004) now "Cisco Unified Communications Manager". So I was wondering, instead of doing a costly upgrade (over 35 000�), maybe it's time to change... Does anyone of you got some insight with Asterisk in an enterprise environment? Is it reliable? Following you own judgement, what are the + and - ? If Asterix worth it, what argument (apart of the price) could I use to help the management turning on my side? Will the Cisco 7921 VOIP phone will be able to connect to it? (as we do have over 35 of them)
Enterprise environment:
- 3 sites (VPN interconnected) - ~35 VOIP phones and ~10 landlines phones
I compiled and installed the Asterisk ztdummy package because there is no rpm for it, unfortunately, and i even reinstalled asterisk, but i still get the "No application 'Meetme' for extension..." error when trying to conference. I do a "module show", and it lists other modules that were compiled with the zt source, but not ztdummy.Does anyone know how to fix this? This is more than a passing interest or hobby, because i need to conference about 3 to 5 people to help me test a new Website Content Management System and User Forums Management System i am about to launch as a service.
I'm trying to setup QoS for my VoIP line on my debian router box. I have tested wondershaper and to me it doesn't seem to work at all, so I'm looking for a better solution. Ultimately I would like something in the lines of [URL] but I guess such nice things doesn't exist for linux. Currently I'm on an ADSL link switching to cable in a few months.
I just got DHCP working, but I need to add a "Pre-Defined Option" for the Cisco VoIP network here. At least that's what it's called in Windows. This "Pre-defined Option 150" is necessary on Windows dhcp servers tied to Cisco VoIP networks, but I have no idea where to start getting that set up in Fedora.
I will soon have a setup consisting of a firewall with 1 WAN interface, and 2 LAN interfaces. One will be a DMZ (With ports forwarded to some servers from the WAN interface), and the other an internal LAN.
Now, I wish to install an OpenVPN appliance, so that i can access my internal network remotely. I'm just a bit confused *where* to place the appliance..
The point of me splitting up the 2 LANs was to avoid port forwarding onto the internal network...
I'm using VirtualBox 3.1.2 (r56127) on Linux (Ubuntu 9.10 64-bit). I'm trying to use Export Appliance utility to clone my virtual machines over local network using SMB protocol to NAS. I decided to do it because some machines are larger than free space on my local disk drive - lack of space for the clones. Simply, I specify GVFS path in the folder selection dialog box, for example:
/home/mloskot/.gvfs/mloskot on browarekhd/VirtualBox/clones
The process starts but after a minute or so the VirtualBox throws an error. Here is screenshot with the exact error:
Does it mean export over network is not supported? Does it mean there is a bug in VirtualBox? Or, simply I must not have used GVFS path as the one above as it consists of spaces in mloskot on browarekhd ?
UPDATE: Maciek suggested below to copy vmdk file to NAS manually. Generally, it would work, but as I specify in my question, I can't generate vmdk file (by exporting VM locally first) on my box where I keep all my VMs due to lack of disk space.
Id like to know if I can import my VirtualBox OSE from Ubuntu 10.10 to Ubuntu 11.10 coming up in April? I will hold off and wait until April, before purchasing my new computer, if I have to build the VirtualBox OSE from scratch, as I have spent a lot of time on it.
Quote: The boxes were designed to intercept those communications without breaking the encryption by using forged security certificates, instead of the real ones that websites use to verify secure connections. To use the appliance, the government would need to acquire a forged certificate from any one of more than 100 trusted Certificate Authorities.
Complete Article It seems like the EFF is still trying to figure what the best way to protect against this sort of attack is. The idea they kicked around about using the Tor network to compare certificates in other geographical locations seems kinda clumsy to me, though. Surely they've got a better approach brewing. How about you guys? Any thoughts to share?
looking for a free LAMP appliance for my Ubuntu machine. I found a DubuntuServerAppliance, downloaded it,and unzipped it,I have a file on computer called DubuntuServerAppliance.ova, which I have no idea what to do with (I wasn't able to execute it, and I didn't find installlation instructions on the download web site).So I am looking for an alternative, or, in the alternative, information on how to install DubuntuServerAppliance.ova.
I have downloaded the Mediawiki demo appliance from UEC store. I have installed it and also it is running. I would like to know how to access the mediawiki demo appliance. I tried accessing it as [URL] but is not accessible.
This isn't exactly Ubuntu specific, but I do plan on using Ubuntu to try to recover this array. I've been using a Freedom9 freestor 4020 for the past few years and other than it totally blowing up last week it's been pretty good. I was on vacation for almost a month and a few days after I returned my NAS (freestor 4020) started acting up. I tried a few power cycles, but was dismayed to see that I could not log in via browser or SSH (SMB shares were no accessible either). A drive failure light is supposed to illuminate if a disk fails, but no dice.
I plugged all 4 drives from the NAS into an Ubutnu 9.04 Desktop system and one started throwing out all kinds of errors. Thinking that it would be a simple rebuild, I went to my local computer shop and picked up another 500GB drive (same manufacturer/part #), replaced the failed drive, and powered up the NAS again... Nothing. I left it for 12 hours then powered it down, plugged the new drive into my linux box again to see if it rebuilt... the drive was a virgin. What gives me hope that I can still recover the data is Ubuntu sees "RAID components" on the drives (through disk manager and parted), and gives me the option of initializing the array.
My plan of attack is to plug all of the drives back into my Ubuntu box, initialize the RAID array via LVM, and pretty much hope for the best. The data is not uber critical, but it would be a pretty big pain in the behind to rip/upload all the software that was on it (ripping hundreds of DVD/CD images is not fun). If my Ubuntu box can make sense of this newly initialized/mounted RAID set... I'll plug in a 2TB external drive, copy the data over, and rebuild the NAS from scratch, then put my data back on (perhaps a different unit, or something running openfiler).
We make network appliances for process control. The owners and operators are not supposed to open them. But they can.
For unrelated reasons, we put our homegrown software onto a USB that is inserted into the appliance. To keep prying eyes off it, we encrypt it. The key is on the appliance internal drive, which can be removed and mounted elsewhere by enterprising IP thief, who can then find the key to the encrypted USB drive.
Any ideas for closing this vector down?
For casual snoopers, we have password protected grub.
Calling cadillackid: would be very pleased to hear about your approach to locking down devices sent to remote premises.
I know there are ways to change the login of a linux box (runlevel 3) so that you don't see the regular login prompt but that you get a list with options. You see this with appliances.
My goal is to create a login like some of those appliances have. Instead of just getting a login prompt you can select several options like login, change network configuration, change password, stuff like that. How can I do this? Is there an Open Source tool to configure this?
We have an appliance with image being installed from CD/DVD installation This appliance image is based on CentOS 4.7 kernel/installer/etc. Everything works fine, we ship this product for about 2 years. Recently I had to move it (port everything) to CentOS 5.5 Everything went fine and it works fine except one minor thing )) We can't install it from CD/DVD image yet. Actually it start fine, finds kickstart file, creates partitions correctly, copies install image to harddrive, but fails the next step when it tries to install RPM's
The message we get:
Quote: the file termcap-5.5-1.20060701.1.noarch.rpm cannot be opened. This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source. If you exit your system will be left in an inconsistent state that will likely require re-installation"
I have downloaded and setup the SUSE Lifecycle Management Server on vmware using the Live CD Distribution. I have connected it to Susestudio.com as my repository and setup a user account via the backend on pg 96 using the slms-admin-ui-user -o to create my administrator account since I lost the password for the initial login. I created a customer and have the following:
Also I have a test box for installing the Live CD of our application. Do all appliance created on suse studio have the client to connect to the SLMS server or do need to install a client? If there is no client how do I obtain and add it to the appliance on susestudio.com ? How do I setup appliance as a client?
I am trying to understand why when running nmap against a SonicWALL firewall at a remote location, the SonicWall firewall is saying that most of its 65535 ports are open? I know this cant be correct and remember reading about how some of these network appliances are setup this way to thwart off attacks.
I have a USB 3g modem, which also supports voice calling, I want to implement IVR ( Interactive Voice response) with it on linux, Can I do it with Asterisk? If yes, then please help me on how to do this ( references) ?
Is there example or howtos available to do this?
Can I develop IVR system in linux without Asterisk?
I want to authenticate and authorize for SiP user of my * box, it is my project, but i did not finish it, hic hic! My asterisk box is version 1.6.0, fedora 10.the first, i downed and installed freeradius to my computer, and run "radiusd -X", it's run normally. Then, I installed radiusclient-ng0.5.6, it's rpm file. All is perfect. But the problem is i can't run asterisk box as radiusclient.
I have been reading about asterisk, I did some basic configuration, a small ivr, record messages.. but I was wondering how and what/where should I modify to use a database to save sip users and voicemail user..then we can add user/voicemail with php-myadmin I always search but I cant find about this configuration..
My asterisk version is 1.6 and Web-MeetMe is 4.0.2 I get the following upon issuing "make" in web-meetme/cbmysql/ :

Has anyone ever had any luck with htpasswd and htaccess on asterisk, I set it up on a test apache server in VMWare just to make sure I knew what I was doing, so It was a very basic html page that I used, however, when I go to implement it on one of my Asterisk Servers, It comes up with the following page after I type a user name and password credentials in:

We would like to install Asterisk with a minimal centos build. We are writing kick-starts to install packages, does anyone know or have to hand a packages list which installs minimum system requirements for asterisk? Preferably this will not exceed the contents of disk 1
I have fedora 13, and installed asterisk.. Before I had centos and have my asterisk running to test and learn.. but in fedora I see there is a http miniserver for admin asterisk..I edited enable, port and ip in the file http.con but when I try URL...I got 404 page no found Asterisk server.
