These settings must only be used under guidance from your BT Sales Engineer.
| Function - Optional | Protocol | Ports | Destination |
|---|---|---|---|
| TLS Tunnel (SIP Signalling / RTP Media) | TCP | 443 | 209.235.5.0/27 8.20.209.0/27 62.239.20.64/27 62.239.15.124/32 217.36.188.192/27 115.160.141.48/28 216.98.191.64/27 |
