  %% Function: address_to_address_and_proto/1
  %% Description: When looking at Via headers, we often have a protocol
  %%              from the SIP/2.0/FOO but we need to look at the
  %%              address to determine if our sipdst proto should be
  %%              foo or foo6. This function does that.
  %% Returns: {Address, Proto} | {error, Reason}
  %%   Proto is an atom, tcp|udp|tcp6|udp6|tls|tls6.
