Yes I have customers using this switch and the 2324 as well.
They work fine even with the IP-500

Subject: [Asterisk-Users] Nearing my wits end....bad switch???
Grasping at straws here...is anyone using a Dell PowerConnect 2224 24-port
unmanaged 10/100 switch in a deployment?
I have two separate asterisk installations with bad one-way audio where the
only common elements left are the Dell switches and Polycom IP-500 phones.
Two different ITSPs - one location uses IAX2 to the outside world, the other
SIP. Two different bandwidth providers, one SDSL 1.5 Mbps and the other T1.
Both locations had Dell servers (different models though), but I've since
replaced one of them with a clone with no improvement. In both locations
the computers were plugged into the switch port on the phones and I've tried
separating them with no luck. The problem occurs with or without a high
network load present and can occur with only one person in the office and
using the phone...
I'm grasping at straws here, but maybe both switches are in some way either
faulty or not suitable for the task? Both were purchased in the same
timeframe in March 2005...
The remote party hears my users fine, but my users get bad audio inbound
from the remote party...below are the specifics for each location:
Location 1:
- SDSL 1.5 Mpbs with static IP, Netopia 4652 SDSL router (enabled
"Prioritize Delay Sensitive Data" to recognize tos=lowdelay per
Netopia
support)
- Dell PowerEdge SC420 with TDM04B (currently only using one port. the
single analog line is call forward on busy to my IAX provider)
- Asterisk CVS-v1-0-02/22/05 (AAH 0.6) using IAX to connect to my provider
over the public internet - I have run pings for an extended period of time
against my provider's server and get no packet loss.
- In IAX.conf: tos=lowdelay, jitterbuffer=yes, also enabled "Prioritize
Delay Sensitive Data" on the Netopia to support tos=lowdelay per Netopia
support
- Average ping time to my provider: 160 ms with no packet loss
- 8 Polycom IP-500's running SIP 1.4.1.0040 and bootrom 2.6.1 using ulaw
only
- Small Business Server 2003 set up as DC for the network
- Two network laser printers
- Dell 2224 24-port unmanaged switch (all phones are home run back to a
patch panel, patched from there into a switch port. The DSL modem, printers
and server are patched into the switch in the same way)
- 8 pc's running XP Pro, all plugged into the switch port on the back of the
IP-500's
Location 2:
- Full rate data T1
- Dell PowerEdge SC1420 (Since replaced with a clone pc) with no TDM
hardware at all (this location connects SIP directly to the T1 providers
Broadsoft switch and does not go over the public internet)
- Asterisk 1.0.7 (AAH 0.9) - using SIP to connect with my provider (not
across public internet, not natted since the Cisco IAD does the SIP mangling
for us)
- Average ping time to the broadsoft switch: 42 ms
- 8 Polycom IP-500's running SIP 1.4.1.0040 and bootrom 2.6.1 using ulaw
only
- Small Business Server 2003 set up as DC for the network
- One network printer
- Dell 2224 24-port unmanaged switch (all phones are home run back to a
patch panel, patched from there into a switch port. The DSL modem, printers
and server are patched into the switch in the same way)
- 8 pc's running XP Pro, all plugged into the switch port on the back of the
IP-500's
Can anyone throw me a bone??? I'm willing to try anything, my next steps are
to run a new cat5 along the floor from the switch to one of the phones to
eliminate the wiring in the walls, and if necessary to purchase a managed
switch that I can do QOS on...
Thank you
Marty
