Hello, I try to use cisco AS5300 with SER, like this : phones -> SER -> AS5300 -> PSTN or phones -> AS5300 -> PSTN | \/ SER But the second form does not work. I don't want people to directly ask for AS5300. So I follow the "Howto" on SER web page. But nothing arrive on SER when I make a call directly to AS5300, The call is forward to pstn. So I make this configuration to minimize the problem. But nothing at all. The "debug ccsip error" tells "no route to destination". Have you any idea ? thanks :) Alcée !
