Hi everybody

I have a project to record a telephone conversation.

My problem is that when I set the modem on recording condition, the voice of other side is being recorded but my own voice not recorded.

Please guide me what setting to be arranged to have both sides’ voices to be recorded.

type of Fax Modem is JUSTEC (Model JM56EA).

I initialized the modem for recording ,with below



I don't know the answer, but I hope you realize that in many countries (like USA) recording telephone conversions is illegal unless (1) you have the permission of the person being recorded, or (2) you have a court order, or (3) you happen to be the President of the US (PM of England will probably do as well)

thank you for your prompt reply
if i want do illegal operation, i could use Telephone Recording Adapter with price $51.95

In any case your problem doesn't relate to C or C++. Please refer the modem documentation, or ask your question from the particular modem manufacturer's support staff.
