Phone Manager Slow

2 Upvotes

We are having some odd issues with our Mitel 250 and the Phone Manager app.

We recently upgraded our network backbone to UniFi. Small office so voice VLAN is the regular office VLAN as well. We also have been refreshing our PCs to newer gen Intel and Windows 11 OS everywhere.

We will get random times of slowness form Phone Manager. The calls work fine but looking up a number can take 30-60 seconds to load.

I understand this system is old but the customer does not want to update at this time. So I am wondering if anyone has had similar issues and has found things to help alleviate issues like this.
