of the codec. By default, Codec1 will be given the highest priority.

addresses and ports of the phone. The first field is for the number to be
dialed. This can be maximum a 10-digit number. It can contain characters
or underscore and hyphen. Next is the IP address of the phone. It should
be a valid IP address in dot-separated form. Next is the port number at
which the phone is running. It can be any value in the range of 0-65535.
