Can't handshake even in 2400 bps

I am using a Encore ENF656 external modem to answer remote calls.
Its initialization string: AT&C1&D2+MS=V22B,0,2400,2400
I am experiencing difficult answering calls: 25% successfull handshaking at 2400 bps.
The calling machine is configured utilizing same initialization string.
Why do this occurr? Is my modem poor quality one? Is it because I have ADSL in the calling and answering sides (noisy lines)?
When i use the calling machine to dial-up my ISP i can get connections at 33600 bps with no initialization strings. As you can see the dialing machine is OK, so I get more confused.
I will increase the points to 500 if I find a working solution.

Checking Ecore's web site, the only external modem listed is the ENF656-EV-CIPR, so I suppose that's the one you have.

The transmission speeds listed are  56000, 33600, 31200, 28800, 24000, 14400, 12000, 9600, 7200, 4800, 1200bps, 1200/75bps & 300bps.

For some strange reason 2400 is not listed. Maybe that's the problem.
Can you try 1200 or 4800?

After more tests, I found the problem.
It was a loose of conection because a PABX equipment installed at Answering side.
lidsky wasted his time visiting Encore's web site, so the points goes to him.
