Ok Tilly, lets try something here....
The concept and colors are super! now, lets see if we can somehow incorporate or 'suggest' SIP into this...
Here's wikipedia's definition of SIP:
"The Session Initiation Protocol (SIP) is a signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP)."
Maybe we can incorporate 'bits' and 'bytes' of data, or some sort of metaphor for phone calls...
