Configuring Linphone with Encryption

If you decided to use SIP TLS - call encryption along with Linphone please follow these steps:

1. Make sure your Main account or sub-account has "Encrypted SIP Traffic" enabled.

Bear in mind, if this setting is enabled and your device sends UDP/TCP or RTP you will be rejected 
with error code 488.

Enable this setting for the Main Account at Main Menu>> Account settings>> Advanced tab.
