[SR-Users] SIP client - Linphone

Mon Oct 5 17:10:06 CEST 2020

Hi Aymeric,
Thanks for your reply. Yes, as you said I get the below warning when I
start Linphone. But the port is actually not used by any other application.
And one more thing is,  I see this error only in case of enabling TCP
transport and not in UDP. So does that mean, linphone works only with UDP
transport?
*Warning: Could not start tcp transport on port 4060, maybe this port is
already used.*
