Re: OnePlus 8-5G Wifi Calling has no sound

It involves opening firewall ports up at your router. The article is filed under "WiFi calling on a corporate network" so how would we find it, right?Wi-Fi Calling on a corporate network | T-Mobile Support Summary of the article: Firewalls IPv4 Address Block: 208.54.0.0/16: PORT / PROTOCOL / DESCRIPTION Port: 500 / UDP / IPsec - IKE : Authentication [WFC 2.0] Port: 4500 / UDP / IPsec - NAT traversal : Encrypted voice traffic [WFC 2.0] Port: 5061 / TCP + UDP / SIP/TLS : Encrypted SIP [WFC 1.0] IPv4 Address Block: 66.94.0.0/19: PORT / PROTOCOL / DESCRIPTION Port: 443 / TCP / HTTPS : Used for handset authentication [WFC 1.0] Port: 993 / TCP / IMAP/SSL : Visual Voicemail [WFC 1.0] Also whitelist the CRL server for DIGITS OTT and WFC 1.0: crl.t-mobile.com 206.29.177.362Visto0likes0Comentarios
