Working together works
"The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angeles. The wireless is the same, only without the cat." - Albert Einstein
IP Multicast Group Addressing
Unlike Class A, B, and C IP addresses, the last 28 bits of a Class D address have no structure. The multicast group address is the combination of the high-order 4 bits of 1110 and the multicast group ID. These are typically written as dotted-decimal numbers and are in the range 184.108.40.206 through 220.127.116.11. Note that the high-order bits are 1110. If the bits in the first octet are 0, this yields the 224 portion of the address.
The set of hosts that responds to a particular IP multicast address is called a host group. A host group can span multiple networks. Membership in a host group is dynamic-hosts can join and leave host groups. For a discussion of IP multicast registration, see the section called "Internet Group Management Protocol."
Some multicast group addresses are assigned as well-known addresses by the Internet Assigned Numbers Authority (IANA). These multicast group addresses are called permanent host groups and are similar in concept to the well-known TCP and UDP port numbers. Address 18.104.22.168 means "all systems on this subnet," and 22.214.171.124 means "all routers on this subnet." Groups in the range of 224.0.0.xxx are always sent with a TTL of 1. Groups in the range of 224.0.1.xxx are reserved for protocol operations and sent with normal TTLs.

In order to reduce the echo try using a headset with microphone and speakers built in, instead of a microphone and separate speakers.
