350x series telephone slow upload speeds for daisy-chained workstations to services like Flickr

Just deployed five hundred 350x telephones, a combination of 3501, 3502 and 3503. - The users are experiencing that it takes 4 times as long to upload files to services like Flicker when daisy-chained via a 350x telephone. What take 15 seconds to upload when connected directly to the 3Com 4500 10/100 Switch, takes 1 minute when connected via the 350x telephone. I doesn't matter what version of the 350x. This issue can be replicated and tested by bypassing the telephone in the daisy-chain and connect directly to the 4500PoE switch.

The connection path is 3Com Switch 8807  (1Gb.to) => 3Com Switch 4500PoE  (100Mb.to)=>  3Com 350x Telephone  (100Mb.to)=> HP workstation.

 

Any ideas for me to try? - Thanks.
