Voip setup - need help
Hello,
I participate in a project in implementing voip in our office.
We have two routers and we just installed 2 dsp cards in the pvdm slots of our routers
I have attached our network setup and i was wondering if this will work
I have little experience in voip and cisco call manager (which will pe configured by someone else)
I am not sure how the ip phone can comunicate over the e1 lines to public pstn, i mean will this work?if not how can i make it work?
It can be possible.

Tryton: server setup (need help)
does anyone around here use tryton? I've installed it and all the modules I'm interested in figuring out, but I am not finding any documentation clearly written well enough to configure /etc/trytond.conf in general. The wiki page doesn't have any real info on it aside from the absolute bare minimum and I am new to mysql/postgresql/sqlite stuff. I guess I am pretty much looking for a tryton server setup "for dummies"... but any help is appreciated. I'm looking to initially set up the server on the same system as the client is running (particularly to get a feel for what I'm dealing with) and at some point separate the 2 and have the server running on a separate system from the client (possibly with multiple clients connecting to that server). Also curious about encryption... Thanks in advance!

i know i asked too many different questions relating to different topics. But i have no clue as to how to set up a server, all i knew was that i want one for my home as we have 5 users and i wanted to share data amongst the users. So i just bought it blindly, thinking that Mac being a super smart computer will do everything on its own my bad, i should have researched first and then bought it.
However i have already asked for a static IP and i as i mentioned to (Toocool) i understand now y you'll asked me to get one.
Security i know is imp, but yet again i dont know how to maximze the security of the server, other than asking the users to input passwords, and that not giving access to all the users to all folders and files including guest user
Thanks a lot anyway and if there is any info u feel i know know about, please do let me know.
Your help is appreciated!!
Regards,

"Critical Errors in Setup" Need help! Setup won't work!
Ok, when I was installing the trial version of Adobe After Effects CS4, a message came up and "Internet Explorer" saying;
"Critical Errors in Setup. Please see setup log for details".
First off, what/where is the setup log?
And, how to fix this problem! Please help!
~MykleI'm sorry, I have no other Adobe Products on my computer installed.

5, it says, "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." I have Windows XP and I need help.
After reading all these posts, one by one did not resolve my problem until I got the very end. Regardless of what step would resolve your problem, these are the steps I would recomment to everyone for a what seems to be a safe and fool-proof upgrade to iTunes 10.5.
1. Stand alone upgrade to the latest Quicktime version
2. Go to control panel and "change" then select repair to the following applications in the order specified by the post on Oct 27. (Notice I skipped Quicktime because it had been upgrade manually,and Bonjour did not have a "repair" option)
iTunes; Apple Software Update: Mobile Device Support; Apple Applications Support
Some of these applications may not appear if they do not apply to your configuration (no iPhone, or no iPad, or other apple devices).
Once all updated, I did not need to restart nor launch any applications, I simply went straight into the 10.5 upgrade, and where it normally got stuck, this time the installation continued for a while longer until it completed successfully.
Great work everyone who contributed! Thank you very much! -
Installing Elements 11 on Mac 10.8.2. Need help with install error: Setup wants to make changes. Type your password to allow this." After entering Adobe password, nothing happens. Locked from further installation. Any ideas? Adobe phone support could not help.
Just before letting changes (installation in this case) be made on the system, Mac OS prompts for password & this has to be the Mac system password. This password prompt is the system's own native prompt & would accept the system password only. Please make sure it is the right system password (all/admin rights) and the installaion should run.

Need help - Catalyst 3550 on CCM4.1 Voip
Guys.
We had a Catalyst 3550 switch fail last week, and the guy who really knows this system has left the company.
The switch has a non-free molecules error, which i believe is terminal.
I've sourced a replacement switch and need help configuring it.
I copied the running config from it's sister switch (there are only 2 switches on this ccm), however, the sister switch is a 3560.
I changed the I.P address and switch name before uploading it to the 3550 on the off chance it might just work.
Show run on the 3550 shows that it might be configured, but when i connected it, it took the gateway down.
I'm really up the creek at the moment unless i can get someone to either look at it, find an old config or get this guy back in for a few hours.
Any advice would be greatly received.
Looking at show run, i see two refernces to VLAN's
interface Vlan1
ip address 170.205.238.3 255.255.255.0
interface Vlan10
ip address 10.10.0.254 255.255.255.0
ip classless
ip route 0.0.0.0 0.0.0.0 170.205.238.1
no ip http server
The I.P address 170.205.238.1 is alien to me.. i don't know what this is. However, what i do know is that i never changed this. This IP address is the same in the 3560.
Could this cause an issue ?. I'm not aware of anything on a 170.X.X.X subnet, this could have been some legacy from the previous owners of the building.
The first 3 ports in the switch are connected to the publisher, subscriber and gateway router.
Does it matter which port is connected to which component. ?
I believe that i can't be too far away from configuring this, but without any help, i'm a bit stuck.

Newbie Needs Help Please - VoIP and VPN
Hello,
I have a question about some voip/vpn configuration. I've got two sites that have 1760 routers with fxo/fxs cards that are going to be tieing the two phone systems together with a couple of voip trunks. These are secondary devices on the network with no data traffic or real LAN even, but addressed with a 2nd wan ip on the fa 0/0 port. The only traffic going through these routers is voice/voip.
My question is about this voip setup with vpn. First off, should I or shouldn't I, or even can I? If I configure a site-to-site vpn connection, will the voip traffic pass over that? How would I set up a VPN tunnel for only the fxo/fxs cards with no "LAN" behind it? Is there a need to have a vpn? Any benefits to sending the voip data across vpn, other than the obvious encryption of the "call"?
The thing is, I've only setup a VPN with Cisco a few couple of times, and once was from a pre-configured script I found and the other was from some software called SDM. I've only known about setting up VPN's for connecting the LAN behind router A to the LAN behind router B. This setup has NO LAN. The only interfaces are the fa 0/0 (getting static wan ip), and the fxo and fxs cards handling the voice. I have no clue on how to configure a site-to-site VPN for this, or if I even can, or if I should.
The next two replies will have my voip configuration as it sits on the bench in testing; I have both fa 0/0 interfaces connected to the local LAN just for a connection and testing, but each will later be getting it's own static WAN IP on the fa 0/0 interfaces:SITE 1:

hello
I need help securing my linksys wireless router with speed boosters. In august me and some friends took over this rented house, and with the house we got their old internett system, we use a linksys router, This nett is open for everyone, but we want to secure it for other users. We didnt get the manual and i've tried the guide on your site but it says it cant be changed. The old owners didnt either know what to do. Is there some help i can get with this? Is there some buttom i can push to reset it and then make it possible?Connect your computer using wire to router. Open setup page of router by typing http://192.168.1.1 in browser's address bar, and typing password as "admin" and no user name, if admin doesn't work reset router and do above step again. Go to wireless tab, here change wireless network name from linksys to any other name. Save the settings. Go to wireless security sub-tab here change security mode to WPA personal etc, and enter you secret key in passphrase/shared key, Save the settings.This secret key will be security key of your wireless network.

hi,
our customer having nearly 30 branches. 20 are connected to central office via leased lines.
And 10 branches are connected by internet.
Now customer willing to use voip on all these branches.
That is From central office to leased line offices and internet offices vice versa..
And there are analog phones with PBXs.
present along with them soft and hard IP phones are required with redundancy.
so anybody can help me in designing this voip setup? (designing means what are the required equipments and protocols for this setup)
Regards
skrao
Regards
skraoSkrao,
Several ways to go here I don't really recommend the VOIP over the internet but your going to have to do a user count and peak call utilzation survey for each site.
Your probably going to go with one of the ASxxxx models for the central site and 2800 or 1800 for the remote sites. As for the VPN offices you might try CME Call Manager Express for them or keep there existing PBX's kinda depends on what there Goals are.
I can't give you specific parts because there is such a huge combination of different ways to go but your gist is you'll probably have a couple of Access-Servers to handle your primary site PSTN connections and then put something that can handle SRST Survivable Remote Site Telephony at each branch office. For your VPN sites your going to want to use Call Manager Express.

Next year we are planning a VOIP migration for some of our in house users. We dont have any WAN connections and bandwidth between floors are gigabit.
What I am looking to do is buy a small setup for our lab this year so I can begin to learn about VOIP etc. So far I have researched and this is what I am considering buying.
- Cisco 2801-V/K9
- VIC2-2FX0 voice interface card
- 3560 24 port 10/100 POE standard image
- 5 7940G ip phones.
Is this a decent setup for the lab ?
Would it allow me to configure a basic voip setup and learn the fundamentals of configuring VOIP ?
Any help would be appreciated.
Cheers
DaveHi Dave,
You can probably get away with this for even less.
You could probably get something like a 1751-V with PVDM-256k and VIC-2FXS with the IP phones. You may need the power bricks in this scenario.
Alternatively,
CISCO2621XM with NM-2V with VIC-2FXS and the phones/bricks
But yes, your current setup will work. You would need to add something like a PVDM2-8, PVDM2-16, or PVDM2-32 for DSP resources, with the number depending on whether or not you want to play with transcoding/conferencing.

Setting Up New FCP5 HD Bay -- Need Help
I'm setting up an HD edit bay for a friend, and I have a number of questions. Any help would be a godsend.
Basically, he's got a G5 with Final Cut Studio installed, a Motu audio interface, a Mackie Mixer, a Decklink Pro HD dual link, M-audio LX4 5.1 speakers, and a DVD/VHS recorder. He has one 250G internal capture drive, and one external 1TB firewire G-Raid. He's running a 23" and 20" Cinema Displays, and a Panasonic 32" HD LCD Flatscreen.
He wants to rent decks per project for capture and output.
My questions is this, how do we output to SD VHS/DVD or other formats for clients? Do we need a Switcher? Is it possible to do format conversion in Final Cut and output via Firewire instead of decklink to SD devices?
Also, is SDI (serial digital interface) cross-platform from SD to HD? Kramer Electonics has an interesting format converter that supports SDI, but will that change HD to SD? Here is a model number and link. FC-7402

Kramer also has a firewire format converter that looks interesting. FC-20

Thanks in advance.You should setup your local DNS to resolve only for the 'film.lab.' domain. Any requests that your local DNS will not be authoritative for should be forwarded to your district's DNS server. You should also set your local DNS to allow recursion only for clients on the 10.x.x.x subnet. The failure of clients configured to use your DNS for name resolution could be due to rules that have bee setup on your district's edge router to block outbound and inbound port 53 requests for all internal clients.
If you set your server and clients to use your district's DNS server as the secondary for your zone, you must make certain that any hostnames within your local zone are defined on your district's DNS to resolve to the private, 10.x.x.x, subnet that you will be running your systems on. If you don't -and your DNS goes down and there is no secondary defined on the clients that contains the zone info for your subnet- your clients won't be able to find any hosts. If you wish to run services that will be accessible from the Internet on your local server, this may require your network admins to make changes to routing to allow those request to be pass from the public network to the private one.
Also, if your district runs a central DHCP server you will need your district network admins to setup their DHCP server to return the correct client settings for your DNS and search domains for the clients within your subnet. If they do run a central DHCP server, do not attempt to set up a local one for your subnet. If you do, the probability that you will receive a very angry phone call from a not so happy fellow at your district is very high. -
Need help with Airport Express and so on.
Ok so my main problem before getting into what I need help with here is that our MacBooks and now my iPhone 6 plus isn't staying online. Keep getting booted off and then I either have to select the network again or it will eventually go back on. If anyone has a solution or so please feel free to answer that as well. I'm running on Roadrunner with a Netgear 600 wireless router and a motorola modem. Both of which I'll leave the link to below for a better look.
My Main Question: So I'm looking at a new wireless router mainly and possibly a new modem. I know Apple products are trustworthy but how good is the Airport Express and other Airport products. Also what is the Maximum speed and Maximum data speed for the cheapest express station and if anyone knows the speeds of the other devices it would be greatly appreciated.DSL Router to Netgear 5-port Switch and I used the switch to connect to Airport Extreme, TV, Blue-Ray DVD player and DirecTV Receiver.
The AirPort Extreme base station (AEBS) is a router so it will do what you need.
You need to reconfigure your setup. Connect the WAN port of the AEBS to the DSL router. Then connect the Netgear switch to one of the LAN ports on the AEBS. The AEBS will properly share the connection.
Maybe you are looking for
