I'm a Finnish man with a Tekcomm v.92/v.44 PCI modem with an Agere controller. My problem is that the modem's output isn't recognized by the phone service; Every time I try to dial using the modem, I get that "The number you dialed is incorrect" message.
What's more curious is that if I pick up the regular phone connected to the same wall before dialing, and listen to the dial-up as it happens, the dial tones ARE suddenly accepted and the call is made. BUT, the resulting connection will not be a very good one and will disconnect soon enough.
I have never run into such a problem before. Could the modem be somehow creating too strong signals, and if so, how can I change this?

What driver version are you running?
(Response to ati3 from Hyperterminal)
If using tone dialing, suggest increase tone spacing - init string
If that doesn't help, also please post your modemlog here

We'd like to know what your codec / line interface chip is: 1034 with a transformer, or 1035A Silicon interface?
Have you tried picking up the parallel phone to let the modem dial, but then hanging up before the modem begins training with the remote modem? You might be able to get by with this workaround.

The interface chip is 1034C-J.
And yes, I've tried what you describe - if I hang the phone up once the handshaking starts, it will go on for like 15 seconds but won't connect (subsequently hanging up), but if I keep listening until the connection is formed, I will have a ~21Kbps connection for like 30 seconds, after which the modem disconnects.
And to answer to v.Richard's query, I'm mainly using driver 8.30 but this problem persists on all drivers I've tried, and altering the *tone settings* probably won't do any good because, as stated, there's also a serious connectivity problem here.

Do other modems on the same phone line calling the same remote modem connect more reliably, or at a higher rate?
Is this a standard phone loop to the telco, or is this a derived POTS line on a terminal adapter? We have seen some truly horrible analog ports on ISDN TAs.
Is it possible that your connection is going through a VoIP gateway, or through ADPCM or some other compression?
It's possible that your modem hardware has a defect. Was the modem working fine until a lightning storm?
If I deperately needed to use the modem I would try whatever workaround was needed for dialing to work, and then +MS=V22B to avoid all echo canceling protocols. I'd be stuck at 2400 bit/s, but at least I could struggle by until I found a better way to connect.

Since the Tekcomm modem does not work, I have been using a GVC (HCF-based) modem instead. While it's not a very good one, it does dial correctly and work stable with a 33.0Kbps connection.
I can't really say anything more about the quality of the cables. I live in a rural area, but like I said, at least 33.0Kbps connections work extremely well.
Anyway - as for a hardware defect, I'm also leaning towards that conclusion, as the modem arrived very roughly in mail and it might've been damaged by lightning prior to that. I installed it two days ago, and before that it's been in use elsewhere (far from here), but I'm told it worked fine.
