VoIP for Small Office

Hi all-
I am new to VoIP technology and currently working on a study for the business on deploying VoIP. Our business is small and currently is connected to the interent via DSL. We do have some Cisco routers and would like to know what is involved in deploying VoIP for our small office!
Thanks in advnace,

You need a router in the branch. As small as an 857 or 877 can do. The difference is that the 857 doesn't support QoS, VLAN and other features, beside that will work fine. The following url will help you:

look not much further than here, I've used this to implement Auto-Qos:

  • Perfect router for small office (2-3 peoples)

    Hello,
    I'm trying to find the most cost effective VoIP solution for one of our small branch offices. This office will have no more than 3 peoples, but each person requires to have a PC and Cisco IP phone (voicemail, multiple line, direct inbound, pstn dial out and etc).
    Building will provide ethernet hand-off for internet access (part of T1 I guess) so we are planning to create VPN connection between our data center and the local gateway.
    As for the PSTN connection, 2 POTS will be provided by LEC. Gateway should be able to accomodate 4 Ports FXO module.
    What would be the smallest but the best router can handle firewall/VPN/IP Voice/PSTN for the small office?
    Thank you very much for your help in advance.

    Hi,
    What drives the price up a bit is the FXO requirement. Cisco used to have a router small as the 1751V, but it is EOL now, so the smaller you can get is a 2801. The price is almost the same but the earlier model was a bit more office-friendly due the box shape and size, while the 2801 is a classic rack box 1 unit.
    The good thing with the 2801 is that it supports POE (optionally), so if you put one 4 or 9 port ethernet switch (HWIC) in the router, your phones can work without the external power supply.
    You can configure the voice system be totally controlled by the router itself with the embedded CCME, or be part of company's CallManager (now CommunicationManager)
    Can I give you another advice, try to get ISDN BRI preferentially instead of FXO. You will have all the features like DID, caller-ID, and much easier setup a diagnostic in the router. Plus, if you add a WIC-1B/ST you can also have ISDN backup using the same data facilities.

  • Making powermac G4 MDD for data center for small office server

    Hi mac expert,
    i had a small office which need to pool every data audio and metadatas ( wav, mp3, flac, mp4, mov, ms office xls, docs, jpeg, tiff ) into 1 place or hard disk that can be access from any macs and pcs in the same office.
    i have 2 units G4 1Ghz MDD (bus speed 133mhz, both has 2 gb of RAM, a 120 gb of HD internal installed.
    i upgrade one of those with DP 1,42ghz and 2TB of SATA hard disk that attached to PCI SATA Sonnet card.
    installed mac osx 10.5.8 leopard.
    airport extreem card installed.
    my questions:
    - How big a hard drive can I get? I installed a 2TB drive with no partion, but sometimes when i open the disk it gave me spinning cursor and it show no items on that drive, got freeze and can not turn of by shutdown menu, i have to press the power button of the mac itself.
    - if i want to make a data center like what i mention above using powermac G4 that i had, what should i do?
    - should i install leopard server os?
    thank you so much.

  • Best way to secure Aironet 1200 for small office

    We are getting ready to install 4 aironet 1200 AP's into an office that will only be used by 5 people with T43 Thinkpads (Intel 2200 built-in card).
    What is the best method to secure the connection and prevent the outside world from accessing our internal network?
    I don't feel WEP/WPA encryption is enough -- Would be interested in using the built in security that comes with the Aironet and not an external security server, yet.
    Any info or push in the right direction is greatly appreciated.
    Thanks

    You could pretty easily use the "local" RADIUS built-in to the AP firmware and implement LEAP or EAP-FAST.
    Both are pretty easy to set up, the AP can handle that small load without any real performance issues, and the Intel client software supports it (you'll want to make sure all the client software and drivers are the most recent, there were some issues in the past).
    Both LEAP and EAP-FASt will support seamless roaming, You'd set one of the APs up for WDS and the others to point to it.
    Admin (add/change/delete users) via the Web GUI is also pretty straight forward.
    Good Luck

  • VPN for small office - 2811 vs RV series

    Hello all
    Need advice
    I have a question regarding what equipment to use for a small remote office.
    We currently have
    5 users
    5 7941 Phones
    1 2811 (Serial, 2 FXS and 1 FXO)
    1 3560g
    All voice devices are controlled from a CUCM 9 in our main offices. The 2811 is also an MGCP gateway.
    They currently connect via a T1, which management wants to disconnect due its high cost, the T1 is connected to a 2811 (C2800NM-ADVENTERPRISEK9-M) with the serial port and analog lines, behind the router we have a 3560G 24 port (POE) with everybody connected to it.
    They have asked me to find out if its possible to switch them to a site to site VPN and possibly replace the 2811 and 3560g with a much smaller device perhaps an all in one.
    I have been looking around and I havent seen any small business router that meets our needs. A fellow tech suggested looking into the RV series routers but I just don't see the devices providing voice services.
    Any suggestions would be greatly appreciated.
    Thanks in advance

    Assuming you have a Cisco 2800/3800 series or better at the main office, I would stick with the 2811 router and do a site to site VPN tunnel. You can actually register the phones across the tunnel and then use SRST for fallback when the tunnel drops. Of course, that will prevent the phones from making and receiving calls without the tunnel, but they will at least be able to talk to each other. If you are really concerned with having at least one working phone when the internet connection goes down at the remote office, you could buy one POTS line from the telco and run it to your FXO port. That line would be used for emergency calls only in the event the tunnel drops. Regardless, the 2811 is way more powerful than the RV series (excluding the wireless part on one of the RV models).

  • OpenSUSE vs Ubuntu for small office

    I might install on two computers (running windows xp now) linux. The computers are used for editing texts (Ms Office now). What would you suggest me OpenSUSE, Ubuntu or something else? It has to be a user-friendly distribution.

    Then imho it depends on who has to maintain the system, not on who will use it.
    Eg my mom never installs a package or changes a setting herself, so I gave her Arch because I have to administer it and I think Arch is the best for that.
    My uncle does want to install packages himself and change his setup him self (without doing too "advanced" things such as using the CLI) so I gave him fedora.
    Dieter spoke my mind, that's a very good point!

  • APC Power Backup Advice for Small Office

    I wasn't sure where to post this but I was hoping someone would not my pointing me to the right forum or offering some advice.
    I am trying to put the finishing touches on a conversion to mac and have been looking at buying a Power Backup in part for the power part (no crashes and safe shutdown) but also for surge protection.
    I have a MacPro (and a monitor), a Time Machine (for the MBP), 2 - 1TB WD externals, a 500 GB Iomega External (for the MBP), a 3DConnection spaceball device and 2 printers on the "desktop". And then I have a 1 TB Seagate External that I keep plugged in on another table for backing up the MacBookPro now and then.
    A. Is there anything else (other than temporary power and surge protection) I should be looking for when purchasing such a piece of hardware?
    B. Should I be getting everything on the "desktop" plugged in to a backup device such as this and if so how do I calculate which device to buy?
    C. Is it a crime to leave the 1 TB Seagate that is not conveniently located off this backup/surge protection system? I suppose it would be wise to unplug it and only plug it in when I am running a backup?
    TIA for any advice. It's been a long haul and I'd love to make sure I am finishing this with some pro level advice/approval.

    Hi Jon,
     ...C. Is it a crime to leave the 1 TB Seagate that is not conveniently located off this backup/surge protection system? I suppose it would be wise to unplug it and only plug it in when I am running a backup?- external hard drives use very little power, you can keep it plugged in to the power back up or not. Since you're not using it often, the odds of it suffering a surge power problem are rare...
    A couple of things to consider in that scenario: first, while it's not necessarily true of all external drives, some, such as LaCie, are noted for the early failure of their power bricks. Since I've been using  a LaCie power brick for over ten years without a problem, I suspect that's because it's not connected to a power source except when it's in actually in use. Even when an external drive is not actually spinning, the power source is still live and perpetual cooking is probably not good for its health. I follow that rule with all devices that use power bricks, including Seagate and WD external backup drives and no brick has ever quit.
    Second, the Seagate external drives I've used tend to run very hot because of poor or nonexistent ventilation. Indeed, the SMART record of one of them showed a heat failure with a 155 degree F. reading "in the past." Especially if leaving the drive plugged in means the drive is actually on, keeping it unplugged except when it's in use is a good idea.

  • UPS suggestions for small office

    I have four Mac Pro workstations and recently experienced a power outage. Two designers lost about an hours work each. Finally decided to bite the bullet and buy UPS systems for all the workstations. Any suggestions?
    All are Mac Pro stations with 26" LCD monitors, external 500g hard drives (one station has 3 backup 1 terabyte drives for video). I only need these to run 15-30 minutes after an outage to save the files.
    Any recommendations would be appreciated!
    Thanks!

    Insure that you are running off a circuit that can handle the load. Adding 4 UPS of 1500VA won't help, and to have 20-30 minutes, I went with an extra battery pack which added 1 hr (now have 75 minutes but there are times when even 15 minutes isn't enough, and 40 minutes was more realistic).
    But you probably want to look at something that would cover patch into your electrical circuit(s) more than just add stand alone units for each. That would be cheaper and easier, under $2k, but a large rackmount that would provide 3000VA costing $8k and up (more like $12k) is what I would contemplate.

  • Small office VoIP system

    Good morning everyone,
    I am currently defining the architecture for a very simple VoIP network that is to be installed in a small office (about 70 VoIP extensions). Initially, we don't want to include any special feature, just the internal voice IP service and the ability to make up to 4 simultaneous external phone calls through PSTN.
    We are going to acquire a Cisco 2921 Router, the SL-29-UC-K9 Unified Communications licence and a VIC2-4FXO. 
    I have been reading about ISR G2 licensing, but I am still not sure of fully understanding what we need for this project. My question is, does the UC licence for the Cisco 2921 include the FL-CME licence to use the Call Manager Express functionality? do we need something else? any special license for the FXOs functionality?
    Thank you for your help
    Pablo

    Thank you guys for your answers,
    Actually, it's my first contact as a developer with VoIP and UC Cisco technology... so I would like to keep it simple at the beginning: just internal voip phone calls and the possibility to ring pstn extensions. Our budget is very limited too... so I need to stick to the hardware that I told you in the previous message: 2921 + fxo card. 
    As far as I have read, SRST functionality is very useful when you have several nodes, to provide survival to each local node that loses connectivity with a centralized call manager. But in our scenario, with a single node... I think we can give up this functionality.
    So, we only have budget to purchase any other license that could be necessary to accomplish this small project. so the key question is: does SL-29-UC-K9 Unified Communications License include Call Manager Express functionality and the ability to use de FXO card to make pstn phone calls as well? because that will be more than enough for us...
    thank you very much
    Pablo

  • Best practices for setting up users on a small office network?

    Hello,
    I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
    Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
    Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
    All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
    Thank you,

    Hi,
    Thanks for your posting.
    When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

  • Setup Lion Server for use in Small Office of Windows & Mac Clients

    I've purchased a Mac Mini Server with Lion Server installed to be used in my small office of less than 10 people.
    The primary goal of this server is to used for File Sharing, bother locally, and remotely.
    In the process of setting up Lion Server I have come across a couple things that I am confused about.
    The first is Open Directory.
    It is my understanding that this is not a necessary setup for the number of users in my office, however I set it up anyway as it appeared to be something that would be useful in the future.
    I have come across information that states Lion Server will not be accessible for Windows users connected via Open Directory. Thus my inclination is to disable the service, and set up my users as local users.
    My question is, for local and remote File Sharing, is there any benefit to using Open Directory?
    The second has to do with Remote Access.
    I am familiar with the notion of a VPN, but I need some clarification as to my remote access options.
    When I go to setup my Server's hostname, I am presented with three options. 1) Host name for local network, 2) Host name for private network, and 3) Host name for Internet.
    I have a domain name for my company's website, so I set up a subdomain (server.mycompany.com), asked my ISP for a Static WAN IP, and pointed thesubdomain to said IP using my DNS. Thus this appears to be option number 3; to allow users to connect to my server from the local network, as well as the Internet.
    My question is, how does this differ from a VPN both in setup, as well as method with which users will access the server? Is there a benefit to one over the other? I would Google this to find an answer, but I can't seem to find a name for what this setup is called.
    I very much appreciate any help you can provide.
    Thanks.

    Well, I spoke too soon.  Lion Server is unstable, awkward and is far too limited to qualify as an Apple product. Even though there's quite a few enhancements, the omissions of technologies in the server 10.6 edition makes this "server" a no go for us.
    Even after installing mysql, I still cannot run a Joomla website on Lion server as it should be done. The wiki's a nice thing to have, but isn't a "professional grade" solution.  There's too much iOS as well.
    With that said, I think it's a shame that apple would put customers through so much frustration and disappointment by releasing such a lame product. In order for us to use Lion server, we would have to be able to run a second (totally separate) instance of Apache. It also appears that server settings are changing to the extent that services become inaccessible as the system is running.

  • SPA8800 and SRST for small branch office?

    Hi All,
    Need some help. I have a central site that will be running Cisco BE 5000. I have a small branch office I would like to place IP phones in so we can just dial an extension to call each other. The branch will have its own connection to the PSTN with a couple of POTS lines from the phone company.
    So I am wondering how I can connect branch and HQ for intra-office calling and let the branch office use their PSTN connection for their local calls. I would think I could place a gateway such as the SPA8800 in the branch and connect the PSTN lines to it.
    My concern is, what happens if I lose the WAN connection between HQ and branch? Then the branch could not make any calls right? I know a little about SRST and how that solves the issue of losing WAN connection with the central Call Manager site, but I what I don't understand is SRST something that can run on a device like the SPA8800 or do I need an ISR router in the branch that can run SRST if I want the branch to be able to make phone calls without a connection to HQ?
    Thanks for any help!                  

    u may but any plane wireless device and run it in bridge mode (shouldd run by default i beleive). Then connect one of its lan port to any one of the lan ports available on the DPC3829 thing.
    you are correct in what you want to do, and it can be done no problem.

    Please mark answer as correct if it helps.

  • Advise about setting up a permissons on Lion server for a small office.

    What is the common wisdom and advise about setting up permissions optimally for a small office using OS X Lion Server as a file server?  I thought I had this solved by setting the ACL permissions so that all users and appropriate groups can read and write all files on the server.  This works great until a new file is created.  Then it appears that the POSIX umask kicks in and takes priority over the ACL permissions.  I need to allow group write permissions on all new files.  My options seem to be:
    Make everyone an admin - not great for obvious security reasons
    Change the umask for the whole machine - also security problems, though perhaps fewer than the everyone-an-admin route above
    Write a folder action applescript to add group write permission on all new files.  This works fine if you have a static number of folders  With new folders it has the problem: How do new folders created by non-admin users get this folder action automatically applied to them - some cronjob to hunt down the new folders; an applesscrpt folder action that adds a folder action to all new folders (sounds recursively complicated)?
    Have a cron job regularly do something like  `chmod -R 664` on all files.  This will break during those between the cracks times between when someone creates a new file and when the cronjob runs - not ideal.
    Seems like this should be easier which makes me think I'm missing something obvious.
    Any help great appreciated.  Thank you in advance!

    Good-heart's advice is certainly your first step, but if you've already done that and still have the problem you've described, you might have the 10.7.3 ACL bug, particularly if your users and groups are in an OD or AD rather than being local accounts on the server. The problem is that ACL's for directory accounts are incorrectly ignored, resulting in POSIX permissions coming into play.
    I've descibed my workaround for this here;
    https://discussions.apple.com/message/18037703
    I haven't yet tried the other trick I've read about, which is to ensure your Share's data directories are at least one level down on the volume - there is a post here on the Communities that mentions this;
    https://discussions.apple.com/message/18028746
    I seem to remember that this helped with an earlier version of AFP, if using external firewire or usb storage.
    Let us know if you find a fix, it seems a number of people have problems with this.

    Ian
