I am using 3640 with BRI4-S/T, and NM-6DM for accepting calls from ISDN and analog modem. ISDN call to 3640 is fine, but when I dial from analog modem to my 3640, on the analog modem always detect busy signals. When I tried to accept calls with 3com ISDN-TA replacing my router, it work fine. Is there any solution or clue for this problem ?
