VOIP phone hanign issue
Hi ,

Earlier i was using netgear GS728 switch as core but getting high latency so i removed netgear and connected cisco SG 550X as core switch and also divided network in two parts. Still i am facing network haning issue in Phone ,
i am not able to find what is the issue suddelny all access switch showing latecny 2000 ms and phone stopped working.
Welcome to the community! :)
Is everything working fine before? Since you have changed the switch from GS728 to a Cisco SG550X and still the same issue, kindly check the IP PBX/Sip Server or Call Manager or the Voice Gateway on your network.
Also, it would be best if you post a detailed network diagram so that other community members can make their suggestions to your concern.
