We bought a cisco POE Switch (Cisco SF 300-24P) from a reseller before two months, and we are facing a problem when we connect just an uplink on Telephone network and it is a standalone network and there is no Vlans connected to this network, the other two switches on this network are LINKSYS SRW224P (Old Product), and the problem is when we dial from POE phones like Linksys SPA922; the tone gone and we can’t hear the one who we are calling and he don’t hear us, but when we disconnect this uplink cable from the Switch above every things come back normal.
