I am experiencing much slower than usual upload speeds when my iMac is connected to my Cisco 7975G's Ethernet switch. I have 75/75 internet with Verizon Fios and my speeds bypassing the Cisco phone are 82 down and about 82 up. When connected to the Cisco phone, my download is able to reach 82 down but my upload does not go past 20. Any idea what might be causing this? The line is operating 100 full-duplex. Thank you.
Would recommend contacting your Cisco TAC support channel for this product-specific inquiry.
