I would like to experiment to have and test to learn more about Asterix.
The modern 3G IP Two way radios using POC /PTT over cellular.
How does one start making and more importantly learning the architecture to run such a POC /PTT server.
Ultimately I would also like
1) Server to interface to an analogue Base radio .
2) Accessible from a SIP connection
3) Accessible from a remote PC using VOIP or similar software.
The radios I am talking about are the iWalkie , F25 , F22 and many more now available .
Thanks in advance
