How to add a gateway to freeswitch without interrupting current calls?

Question

Telephony

Have a nice day, everyone.
I ran into a problem: there is a freeswitch, to which users are connected, making calls to the outside world through different gateways. I need to add new gateways (multiphone, sipnet, etc.) so that other users can connect and call through them. But the problem is that if you do
sofia profile external restart
that, the current calls will be cut off. Can you please tell me how to add new gateways without interrupting current calls? Is it possible? In which direction to dig?
PS reloadxml does not help, the added gateway does not appear in sofia status and when you try to call, this error occurs
Invalid gateway

Answer 1

add everything that is not added
if you need to reread the config of a specific gateway

sofia profile external killgw название_шлюза
sofia profile external rescan

Answer 2

reloadxml
