OT, as there seems to be alot of PBX partners on this forum.
I've seen and used alot of cloud solutions. I don't have any issues with them - the only issues are networking issues, like ALG and stuff...

Our Avaya partner won't even do sip trunks on any prem solution if there is no SBC. QOS and all that stuff.....

TT Tommy. Do share some more details. I've never even knew there was IPO in the ~cloud~
