I wonder if anoyone can help.
I’m trying to establish 4 voice channels across the internet.
On one side I want 4 telephone sets and on the other side I would like to connect to the PSTN.
Can someone suggest a good-quality and relatively cheap solution. I have seen some good offers for the Ericsson P4 Webswitch but this doesnt allow direct connection to the PSTN as it does not have FXO capability.
Also, is G723.1 the best vocoder for relatively poor internet connections ? Does anyone know how each algorithm performs, I mean with delays and packet loss.
