@aniliri,

 

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.

We don't have Vlan and this is simple network and only 25 users with phones are connected.
