Re: [on-asterisk] Hardware specs for 40 seats
Bruce, If you plan on a lot of recording and storing it, I'd not do it using Raid5, writes are slower and it it could affect system performance. I'd go one of two routes, either use a SAN with NFS or iSCSI and write to this using it's own nic/subnet. Or look at a separate recording server utilizing Oreka with a tap on the voip vlan. Just a thought. Mike Bruce Nik wrote: Thanks for the overwhelming input guys. Other than the messy setup with a bundle of 25 pairs unshielded cable, is there any other problem that I may face?

RE: [on-asterisk] Hardware specs for 40 seats
I appreciate the tip. You make the second person not recommanding a RAID5 for recording. I know that they have Meridian in place and some sort of a box connected to it to record calls. They say they get a .wav file and can e-mail it. They would like to keep that feature. Anyone who has worked with the legacy PBX would know if I can use that with Asterisk? Besides, I was just told that the provider is bringing in 23 business lines rather than PRI until next few months. So, I should be looking in gateways now or use the old Meridian for now...I am also surprised that they can't port a 416 number from another provider to the new location which falls under 905 area code. Client has to keep both providers and forward from one to the other Date: Tue, 9 Dec 2008 09:32:02 -0500 From: [EMAIL PROTECTED] To: asterisk@uc.org Subject: Re: [on-asterisk] Hardware specs for 40 seats Bruce, If you plan on a lot of recording and storing it, I'd not do it using Raid5, writes are slower and it it could affect system performance.

Re: [on-asterisk] Hardware specs for 40 seats
Hi Bruce, there's been a lot of opinions posted on networking hardware and cabling. Mostly good advice but some sounds like the sales pitch direct from a tier 1 switch vendor, eg FUD. These are established best practices in cabling and will help you keep your hair and happy customers. (Yes, you can do voice and data on one cable but the extra, up front cost of two will pay back many times over in maintenance and support costs). Cabling: Two CAT5e cables to each station, home run from the server room. Use proper patch panels and wall plates. Always use pre-made patch cords. (Home-made ones are a world of pain). DON'T use 25-pair cable. Too hard to work with. It's meant to run between wiring closets or in large data centre applications, not to the desktop. Probably a lot less heartache to have a professional cable guy do this if you want it neat, tidy and working, but shop around, don't go ultra-cheap and talk to happy customers. Switches:- 2 x Dell managed 48-port 10/100 switch will do this job nicely. One PoE, one not. Modest price, good feature set, excellent value. Just plug and play if you want. Don't fall for the better support from VendorX BS. This is not rocket science anymore, IT'S JUST A SWITCH!!! Smaller offices do better with separate switches for voice and workstations. This avoids confusion on the part of the office techies. Larger installs you can divide each switch into two VLANs, one end for voice, one for data. Label clearly for the VLAN unaware. The Aastra phones use ~3W apiece, apparently the Linksys are similar so you don't need to pay extra for the full power option that some vendors charge. Server: I'm not so opinionated here but most modern servers will do this without breaking sweat. RAID 1 with hot-spare, not RAID 5. A 6-line call centre I manage has been recording all calls for 2 years. Disk usage? 20GB. 3TB might be overkill, but disk is cheap. Remember this is Linux based and adding disk space is not a big deal like Windows. Oh, and remember to back it up ! Phones: I use Aastra, basic text files for central provisioning. Polycom have a good name but I believe the provisioning is more involved as the XML config files can be tough to manage. UPS: Most people expect their phones to work during a power failure. You need to calculate your needs for a long runtime rather than the usual KVA or power requirements. regards, Drew Bruce Nik wrote: Hi guys, I am just drawing diagrams here and trying to find out what equipment I need for a 30-50 seats.

Re: [on-asterisk] Hardware specs for 40 seats
Bruce, 1.I would recommend Astra 9133i . Which is very stable phone. I am using this phone for a 80 seats locations for 2 years . so far no problem. I Never use the Astra 51i . But I can say Astra57i lots of problems. 2. Raid 5 is very slow. If you really want the redundency. I would recommend use the Raid 1 + one spare disk. 3. Separate cable for voice and data. This will help you a lot down the road. Hope this helps. Lloyd On Mon, Dec 8, 2008 at 9:43 PM, Bruce Nik [EMAIL PROTECTED] wrote: Thanks for the input guys.

Re: [on-asterisk] Hardware specs for 40 seats
I can tell you that we have had good experiences with Linksys overall, but absolutely HORRIBLE experiences with the SRW248G4P. The switch has QoS capabilities and we found that if we tried to turn any of it on the switch became very unstable. We found the only way the switch was usable was at factory default settings without taking advantage of any of its features. At this point, it was a dumb PoE switch only. - Original Message - From: Bruce Nik [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Cc: asterisk Mailing asterisk@uc.org Sent: Monday, December 08, 2008 9:43 PM Subject: RE: [on-asterisk] Hardware specs for 40 seats Thanks for the input guys.

Re: [on-asterisk] Hardware specs for 40 seats
Well, if I could chime in here... I have the 51i, 53i 55i and 57i in my office and I would recommend that you try to stay away from the 51i. No headset option. If you have that many phones that need recording, then they probably would consider headset either now or in the future. If you have any budget at all left, I would make the jump to the 55i as technically, it is easier to use and provide services to the users on. Not necessary if only basic phone services is required. If they don't want he lastest look, then I would use the aastra previous style phones, but keep the same approach, make sure it supports the new firmware and offers headset options.

Re: [on-asterisk] Hardware specs for 40 seats
I would also suggest the same. Use a packpole and put them all down the same channel if you want to have a clean look. I would suggest that you run the cables, but run cat5e to every port. Then in the back room you can swap it out as you like. This way you have a failsafe also. But then it is at least clean, easy for the future and will cause no headaches. besides, cable is cheap. Unless it is a long run!. If it is a long run, put the switch closer and run the gigabit with 4 runs to the server and gang them together so you get 4GB data pipe.

Re: [on-asterisk] Hardware specs for 40 seats
53i does, but you might want to do some testing with it first. I have not had much time to work on this yet. When I first put my server in place, I had issues with the echo so the headsets were a real problem. But now, I have that fixed and have not gone back to try it again.

I have the 51i, 53i 55i and 57i in my office and I would recommend that you try to stay away from the 51i. No headset option. If you have that many phones that need recording, then they probably would consider headset either now or in the future. If you have any budget at all left, I would make the jump to the 55i as technically, it is easier to use and provide services to the users on. Not necessary if only basic phone services is required. If they don't want he lastest look, then I would use the aastra previous style phones, but keep the same approach, make sure it supports the new firmware and offers headset options.

Re: [on-asterisk] Hardware specs for 40 seats
Hrmm. I know the SS 3300's don't do POE, besides, they are pretty old. I've had a bunch give up on me over the last 3 or 4 years. I'm not much into building out large scale voip, (I build out/troubleshoot large scale medical image systems :-) ). I cringe every time someone says Linksys. I know, I know, they are cheap. I even have a blue-box wireless Linksys at home too. Does anyone build solutions with HP Procurve. Lifetime warranty has come in useful for us on a few occasions, but are just as reliable as any Cisco, and sometimes much faster imho. This one could fit - J8165A - ProCurve 2650-PWR PoE stackable switch with 48 PoE-ready ports plus 2 10/100/1000 ports (Copper or mGBIC option). For the POE requirements, from the FAQ: *Q: How much Power-over-Ethernet (PoE) wattage is available for each of the 2600-PWR switches?* The 2626-PWR and 2650-PWR have internal power supplies that can supply up to 406 Watts of -50V DC for the PoE devices. For the 2626-PWR, that’s enough to supply 15.4 Watts per port for all 24 10/100 ports, the maximum allowed by the 802.3af specification for Power Sourcing Equipment (PSE). For the 2650-PWR, 406 Watts is enough for 24 ports at the maximum allowable wattage, or all 48 ports at an average of 8.4 Watts (the typical wattage requirement for IP Phones). We use Procurves in our lab environment at $WORK, for data and ISCSI too. Just a thought /M Bruce Nik wrote: Thanks for checking the model number.

RE: [on-asterisk] Hardware specs for 40 seats
Thanks for the input Mark. I like new ideas. Since Linksys is getting really mixed ratings, I don't mind buying another type of a switch. Someone here asked about the budget for the switch or 48 ports: there is a max of $1000. Of course, I don't want to use all the money :) - I would stay away from the Cisco, even though I don't have any problem with setup (CCNA Certified), but the price is not justifiable for this place and it's an overkill probably. -Bruce Date: Mon, 8 Dec 2008 22:38:41 -0500 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] CC: asterisk@uc.org Subject: Re: [on-asterisk] Hardware specs for 40 seats Hrmm. I know the SS 3300's don't do POE, besides, they are pretty old. I've had a bunch give up on me over the last 3 or 4 years. I'm not much into building out large scale voip, (I build out/troubleshoot large scale medical image systems :-) ). I cringe every time someone says Linksys. I know, I know, they are cheap. I even have a blue-box wireless Linksys at home too. Does anyone build solutions with HP Procurve. Lifetime warranty has come in useful for us on a few occasions, but are just as reliable as any Cisco, and sometimes much faster imho. This one could fit - J8165A - ProCurve 2650-PWR PoE stackable switch with 48 PoE-ready ports plus 2 10/100/1000 ports (Copper or mGBIC option). For the POE requirements, from the FAQ: *Q: How much Power-over-Ethernet (PoE) wattage is available for each of the 2600-PWR switches?* The 2626-PWR and 2650-PWR have internal power supplies that can supply up to 406 Watts of -50V DC for the PoE devices. For the 2626-PWR, that’s enough to supply 15.4 Watts per port for all 24 10/100 ports, the maximum allowed by the 802.3af specification for Power Sourcing Equipment (PSE). For the 2650-PWR, 406 Watts is enough for 24 ports at the maximum allowable wattage, or all 48 ports at an average of 8.4 Watts (the typical wattage requirement for IP Phones). We use Procurves in our lab environment at $WORK, for data and ISCSI too. Just a thought /M Bruce Nik wrote: Thanks for checking the model number. There is already 3Com® SuperStack® 3 Switch 3300 24-Port in place but I don't beleive it does POE and prgramming it would be a nightmare... I won't mind dropping another few pairs to separate the PC from the phone but that also means cost of another switch. Maybe I can use the 3COM switches just like they are being used now. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] _
RE: [on-asterisk] Hardware specs for 40 seats
Thanks for the overwhelming input guys. Other than the messy setup with a bundle of 25 pairs unshielded cable, is there any other problem that I may face? The person who runs the cable will let me know if there is any price difference or if it would make his job easier to simply use 25 pairs. I have to decide that VS Cat5e (which again shouldn't be that expensive from what I read???!!!)

Shorter cables and smaller loads would have less loss.

Re: [on-asterisk] Hardware specs for 40 seats
Make sure the 25 pair cable is really cat5e - many 25 pair cables are really only rated for voice. I suspect most installers would prefer installing 6 smaller cables rather than a single big ( .5 inch ) cable. - Original Message - From: Bruce Nik [EMAIL PROTECTED] To: asterisk Mailing asterisk@uc.org Sent: Tuesday, December 09, 2008 12:11 AM Subject: RE: [on-asterisk] Hardware specs for 40 seats Thanks for the overwhelming input guys.

let us not forget the fxs gateways that can take so much of this networking skill set pain away :) and they are getting cheap now. -Original Message- From: TianLun Song [mailto:[EMAIL PROTECTED] Sent: Sun 12/7/2008 11:14 PM To: Jim Van Meggelen Cc: Bruce Nik; asterisk Mailing Subject: Re: [on-asterisk] Hardware specs for 40 seats if you are not good understanding of QoS, Cisco develops a tool called AutoQoS on its mainframe switch which is to facilitate QoS setup. it is a very simple command under interface level. however, the switch from CISCO is very pricey. another opition for you is linksys and it works well if you know QoS and VLAN fully.

In theory, this is not necessary since a managed switch should be able to deliver PoE, VLan, and QoS over a single wire, but when all the costs are added up, it can still be cheaper to pull two (or even three) separate runs to each desk, and then run it all on cheaper network switches (since you don't need the Vlan and QoS for the VoIP anymore).
