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

[mailto:[EMAIL PROTECTED] On Behalf Of Marty Mastera 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 |
