[Asterisk-Users] Packeteer ? Edgemark ? How to not re-cable ?
I have customer wtih 30 stations in cubicles but they only have 1 rj45 per cubicle and that is for lan and internet. I would prefer the voip to be on separate net connection for quality purposes but customer does not want to recable. How to avoid voice quality problems ? I have read about devices like Edgemark or Packeteer that can prioritize voip udp. Is that true ? Do they work ?

[Asterisk-Users] Packeteer ? Edgemark ? How to not re-cable ?
As long as it is a decent 100mbit switched LAN and your switches are not saturated with traffic, you should just be able to plug in the phones and it will work fine, no prioritization is necessary. A 100mbit full duplex connection has a potential bandwidth of a few orders of magnitude above what a VoIP data stream requires. If your customer is just doing normal web surfing, telnet screens, Outlook, etc there should be no problem. A device like Packeteer is designed to shape traffic at a demarcation point i.e. your broadband connection. It would be of little use to you inside the LAN unless you bought a Packeteer for each and every station, which would be expensive to say the least. hth -----Original Message----- From: A_ Navone [mailto:navone2@hotmail.com] Sent: Tuesday, December 06, 2005 1:11 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] Packeteer ?

Why not try the following, there are plugs available that replace the current RJ45 outlets, or plugin an normal outlet and split the cable in 2 times RJ45. See http://www.datorhandel.com/se/products/679-F or http://www.abccables.com/ca-003805.html for an example you would need 1 at both ends, or in the patchroom recable only on that side.

Generally I'm not a support of this, but if recabling is impossible or to expensive it might be a solution. It's doesn't make the patch rack look any prettier.. ;-) Stijn -- Met Vriendelijke groet/Yours Sincerely Stijn Jonker <SJCJonker@sjc.nl>

check out www.exinda.com if you are looking for a cheaper solution to Packeteer, also offers more functionality as the design is third generation.

Don't use Packeteer, we have used that in the past (although not for voip application) & we had too many complaints from our subscribers. We are an ISP. -----Original Message----- From: Stijn Jonker [mailto:SJCJonker@SJC.nl] Sent: Tuesday, December 06, 2005 4:15 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Packeteer ?

Do they work ? > Thx in AdvanceWell, you have a number of choices: 1.) Buy a phone that has a built-in switch (Cisco, Polycom come to mind). Unless your LAN is really, really heavily loaded, you shouldn't run into any problems whatsoever. 2.) I assume that your customer currently has one RJ-11 phone jack in each cube, in addition to the RJ-45 data jack. In that case, don't use VOIP phones or ATAs. Use analog phones or even ADSI analog phones connected to a T1 channel bank, connected in turn to a T1 card in the asterisk box. No QOS problems, no rewiring. 3.) If you don't want to buy phones that don't have a switch built- in, buy small netgear 5-port switches and use them instead at each workstation. One downside of this approach, however, is that the switch is just one more item for which you have to provide a backup power source if you want your phones to work when the lights go out. Those would be my recommendations, in order of preference.
