Actually it is not trying to connect.
It just does a connect() system call on a udp socket to this ip address, which 
just has the effect of setting the local address of the socket. No packets 
are going to 2001:638:500:101:2e0:81ff:fe24:37c6.
This local address is then retrieved to be used in SIP and SDP messages.
The 2001:638:500:101:2e0:81ff:fe24:37c6 is actually a randomly choosen public 
IP address. The goal of this lookup is to find the local interface (ip 
address) that is able to communicate with the public internet.
