To seamlessly use the ORENcloud (OUC) Softphone it might require you to ensure some settings are Disabled and Ports to be opened outbound to our server(s).

1) Ensure ALG SIP, SIP Inspection, etc on firewall, router, etc is Disabled

Please ensure SIP ALG / SIP Inspection is disabled on your firewall. The setting name varies by vendor — Check Point calls it SIP service inspection, Fortinet the SIP session-helper — so for corporate environments please check with your security/network team. For home setups, refer to our KB article: ALG SIP on firewall, router, etc.

2) Ports Required on firewall, routes, etc.

In most home Internet routers & modems these ports are not blocked but if you are in a firewall environment -like your office- the following Ports must be opened. 

Depending on which server you are on, the firewall rule assumed here is

Source = You (i.e. Your Public IP)

Destinations IPPBX = 210.1.230.83 (<your_domain>.oren.cloud)

Destination OUC Provisioning = 159.203.163.250

Destination STUN & TURN = 157.230.245.31 (stun1.oren.cloud)

Port = Required to open
