[Freeswitch-users] Freeswitch failed to initiate outbound call using SIPs + SRTP (SRTP unprotect )

Sun Oct 21 03:50:08 UTC 2018

Thank you Safarov for your solution.
I am not quite sure about reverting the dial-string part.
Could you please electorate on how can I revert the dial-string?
Do I need to remove the dial-string from the dialplan or from the user
directory configuration?
Thank you in advance.
