I love that it allows me full control over my calls, voicemails etc without needing access via another device or software application - this makes things super easy! The customer service side has been fantastic too (as always!).
Nothing really at all but would be nice if you could have more call features within your system which isn't possible due limitations from our cloud provider partner? It's great for small businesses who donโt want additional costs associated by traditional PBXs/SIPโฆ
