  • In order to receive incoming calls all the time enable "Push Notification" and set 300 for "Expire".


  • For better results, in the Network settings of Linphone disable the option "Random port" and set the port 5060, 5080 or 42872 (For encryption 5061, 5081 or 42873). Also, set the range 10000 - 20000 for the Audio ports.

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.

For a sub-account enable it at Sub accounts>> Manage sub-accounts by clicking on the orange icon with a pen and finally click at "Advanced Options (Click here to display)".

2. Now that your account/sub-account has this setting enabled, your Linphone needs to send TLS and SRTP.

  • You have to select TLS as the transport type when adding the account.
  • If the account is already added go to the Account settings in Linphone so you can edit this option.


  • Finally, from the Call settings in Linphone set "Media encryption" to SRTP and enable "Media encryption mandatory".
