Task: dial-up internet via mobile phone using call back

Mar 30, 2009 5:02PM PDT

what i wish:
1. connect to internet using my mobile phone's dial-up MODEM (not GPRS/WAP/etc),
2. the connection should be established after ISP's call-back.

what I have:
1. PC,
2. mobile phone (Samsung D600) with free incoming calls,
3. USB cable

what I managed so far:
1. connect the phone to PC,
2. dial the ISP number and pass authorization

what is the problem:
1. ISP is initiating a call-back, but mobile phone not responding to it.

SOLUTION???

That's going to be tough as almost no phone made today has a modem for dial up any more and no one has plugs to go to the PC modem.

I looked at the d600 "spec" and found no dial up modem in the phone. Can you share what spec lead you to believe there was a dial up modem in there?

connection established BUT ...

Thank you for prompt reply,

"luckily" my phone is quite an old one (2006) to have a modem inside. Actually, after my last post I was able to connect to ISP, though without a callback.

I established a standard connection (in XP: Network connection > Create a new connection), entered login and password, hit connect. Mobile phone dialed the number, ISP checked password and I got connected, though with only 9.6 Kbit/sec Sad Another attempt with another ISP yielded the same slow 9.6 Kbit/sec.

But when I tried to use call-back, everything went smooth (dialing number, checking & confirming password, initiating call-back from ISP) until ISP calls my phone. The phone can't "identify" ISP's call. It just keeps ringing, and if I press green button on phone, no sound, no action.

Normal landline phone would ring twice and PC's internal modem answer the call (remember that squeaky modem sound?) and connection established.

So now, the task shrinks to "how to make Samsung D600 answer incoming call-back from ISP"? Otherwise, getting connected does not make sense, since I have only incoming calls free.

p.s. what about connection speed? is 9.6 Kbit/sec maximum I can get?
modem parameters show whopping maximum connection speed of 460 Kbit/sec.

9600 baud sounds right.

We don't have the analog bandwidth so modem speed would drop.

As to the dial back, I can't find any documentation to support what you want to do. Let's call that a dead end.

To get past that dead end, find the documentation for the phone and the modem commands that would enable auto answer.

-> Remember that I can't find this documentation. So it's all up to you now.
