EMG 80 with LIP Handsets with buzzing on all External Calls

EMG 80 with LIP Handsets with buzzing on all External Calls

EMG 80 with LIP Handsets with buzzing on all External Calls

(OP)
Question : Emg 80 with LIP 9030 Handsets on customers network ,through POE8 & 16 Port tp link switch .

Lines are through a Cisco 8 Port IAD ..

Problem - On all external calls buzzing noise coming through all LIP handsets ..

Internal Calls are fine , Have plugged in Digital Extn & Analogue Extns & external calls are Fine..

Have also taken another system to site & same fault ..

Some sort of Interference on the LIP Handsets Perhaps ?

anyone experience an issue like this?

RE: EMG 80 with LIP Handsets with buzzing on all External Calls



any reason your using a cisco 8 port iad instead of just using the voip channels on the system ?

perhaps a codec mismatch perhaps .

i have never heard of bussing befor eon lip handsets tbh .

try different poe switchs perhaps.
