Hi Kiran, Here are some suggestions from my past experience from one of the dial IP setups in India. Your config seems to be OK. 1. Try connecting through an external modem (any known good vendor like USR, Boca, etc.) if you can change the modules or if you have a spare Asnych module. If that works properly, then change the 16 port modem module itself. 2. Check whether your telephone lines are without any hitches like noise, improper termination, etc. I assume you are using analog telephone lines for this Dial IP setup. Some of the COs in India give out what is known as battery reversal (especially the CDOT ones), If that is the case, then you will have to ask the CO to disable or give you another line without battery reversal. You can verify the battery reversal with a CRO or an analog multimeter (normally the digital ones won't be able to capture it). Good Luck.
