SoTCP Internal Call

Once the destination IP node receives the

 

 

Accept

ACP call accept from the remote voice

 

 

 

port, it sends a SoTCP Internal Call Accept

 

 

 

to the source IP node. The remote port’s

 

 

 

UDP port number is included in this packet

 

 

 

to inform the other end of its UDP port

 

 

 

number. The connection between the nodes

 

 

 

is now established.

ACP Call Accept

The source IP node sends an ACP Call

 

 

 

Accept to the voice port and the port may

 

 

 

begin to send voice packets to the

 

 

 

destination.

 

 

 

 

 

 

 

 

Data Transfer

The SoTCP protocol attaches the 3 or 4-byte header to the packet. The SoTCP

 

protocol then sends voice packets over the UDP channel.
