I have an issue with accessing a PBX (CS1K) via a US Rootics modem.
The modem answers ,but no tones are exchanged.The access to the modem is via a DDI extn down a EURO ISDN pipe.
If I access the modem from an internal extn it answers and handshakes every time.
I have tried replacing the modem with a new one,same result.
