Firewall Destination Ports for Client Apps

[buggycode]

Hi

We are running a hosted 3xc service (hosted by a thrid party). We have a locked down notwork, ie heavily restricted outgoing ports going to the interent, no incoming ports at all. What outgoig ports and protocols need opened to allow 3xc client app (on iphone, android and possible dektop cleint), to make and recieve calls and messaged from out 3cx system?

Currently only list are:
433 (TCP)
5060, 5090 (TCP and UDP)



Is that all that is needed?

Thanks

You can check the firewall settings here. However, it won't work properly without inbound ports.
